Reviews For: ADT Security Services
Each one of these ADT customer reviews have been submitted anonymously by present or former ADT burglar alarms clients.  Please note that ADT uses a sub-dealer program, which usually means that an authorized dealer will install and service your alarm, and ADT will monitor it.  So a review listed here may not be for or against corporate ADT, but a completely independent local dealer.  If you submit a review, please indicate whether the review is regarding ADT corporate, or the dealer who installed your system.

(Added Aug 14/13) We have had ADT for 3 years & have never had any problems. We have recommended it to friends & they have had it installed & have had no problems either. Last year a Vivint salesman came to our door & my husband invited him in.  I was not home so my husband spoke with him. The Vivint salesman put his feet on our coffee table while trying to talk my husband into cancelling our contract with ADT. Very unprofessional! We definitely will stay with ADT.
(Added Jul 3/13) I would not use ADT as my home security providers ever again.  After 2 1/2 years, I had an old door replaced. In the process, my husband misplaced the small magnetic piece that goes to the door sensor.  We called for a replacement and were told that we will have to pay 100.00 for a tech to come out to replace the small piece.  I could not even believe what I was hearing. In addition, they recently increased my monthly payments. The crazy thing is that they didn't care or try to work something out for me when I voiced my complaint about this ridiculous price. So I opted to end my contract early, pay the penalty, and be done with ADT.  I found another company that will provide the same service for 50% less than ADT. I will get 2 (not 1) key remotes, my monthly price stays the same for the entire contract, and they will replace parts, pieces free of charge.
 
(Added Jun 27/13) Customer service is poor and when I stayed on line to conduct the survey they never answered the phone. After canceling service they continued to charge my bank acct an additional 2 months.
(Added Jun 27/13) Purchased new home in 2005 (Colorado), installed ADT wireless to home landline phone. I travel extensively on business. The only call I ever got from the local ADT dealer was I missed a payment while I was on the road. I disconnected our landline phone to see what would happen. Nothing. No call. No check from police or the ADT local company. Nothing. What a scam. We eventually cancelled our landline phone and now have cell phones. The system is still installed and beeps every time we open/close doors. Our ADT had been paid in full but we do not pay any monthly/yearly fees. What a complete waste of money. Our son is back from tour with the US Marines - that is all the security we need, believe me.
(Added Jun 7/13) 2006 Alarm system were purchased by the previous owner of a business I purchased.  When I relocated the business as an act of good faith with the previous owner and the company I agreed to take on the debt...(read the whole review)
(Added May 29/13) Adt service is the worst ever, they blame all their subs for any problems but do nothing to correct the situation. When you call adt the folks that answer are very, very rude, do nothing to help....absolutely nothing!!!!  They will argue themselves blue explaining how it is your fault their service guy was unable to respond. I took a day from work, drove 180 miles to our home near our family...twice!! to meet their tech to have a system installed and no one from ADT showed...twice, now we had it set up for a service call at our home in another town, yesterday, no one showed....real easy to find better. Nothing worse!
(Added May 27/13) I am an original Brinks customer and now an ADT customer for 18 years combined.  I liked Brinks a lot and I can say that I never had a problem or heartburn with Brinks.  I can't say the same about ADT.  With ADT, I am only a billpayer.  ADT has a sophisticated automated billing system that will robo-call you the day that they determine that you are getting behind on your bill.  Yes...yes...I know...pay your bills on time and there would be no need for ADT to harass you.  Well, I now owe $76.96.  $37.99 of this amount is due in 12 days!  ADT is now robo-calling my house asking for full payment!  Brinks never treated me this way and I never had my account referred to a collection agency (90-days delinquency).  When you call ADT's customer service, you will likely talk to an illiterate & ignorant person whose tone suggests a ghetto arrogance and self-righteousness.  This person will confirm all of the stereotypes that is what is wrong with black America.  You see, many companies receive corporate tax breaks when they hire poor people who receive government aid.
(Added May 22/13) Buyer beware, ADT will lie to you and doesn't explain to you that they will automatically renew your contract without notifying you. They expect you to remember the exact date of your contract expiration date after years of service, which they do a lousy job at. They call you up when the alarm is activated and you will have to call police yourself or go yourself to inspect the problem. I called ADT in July 2011, wanting to cancel my contract and they told me I had to wait until the following year to cancel since I had a 3 year contract, and it expired in February 2012 of following year.  In February 2012, I finally found my contract and found out I only had 3 months left on my contract, it was to expire in October 2011, so they renewed my contract automatically. I finally cancelled after sending them 3 letters of cancellation, which they said they never received and ADT is harassing me for the balance of the months left on the contract. ADT lied to me in order to renew the contract automatically. I will never use ADT again.
(Added May 14/13) My husband and I had ADT for as long as I can remember for our residence in Florida. I finally took the leap and cancelled the service due to:..(Read the whole review)
(Added May 7/13) Beware, don’t give ADT a credit card number.  They are a joke.  I had an alarm installed and was set up on 3 payments for the installation. After 2 months I still couldn't get them to take the first payment then when they finally started taking payments out of my account they took 1 and then took the balance the second time. Then we had video cameras installed in October was supposed to be set up on 3 payments again with the first one in October.  after calling 5 times was told that they lost my contract and would mail me another one to sign. Now I find out that they took out almost $700.00 out of my bank account that I didn't expect.  I guess they found my contract. Now I have to cancel my credit cards because they like to take money out whenever they please. ADT is a joke!!!!! Would not recommend there service to anyone!!!! Do yourself a favor look somewhere else for monitoring.
(Added May 7/13) This company should be put out of business immediately.  The customer service is absolutely atrocious, you cannot get any answers from anyone, no one knows anything there other than collecting your money for a service that does not work.  I initially had my ADT system installed in October 2012, it never worked, I have had several technicians come out to solve the problem but it was never solved.  I am now in the process of having ADT come and pick up their equipment immediately with the return of all of my monies paid to them for an inadequate alarm system.  Please do not waste your time or money with this company, I urge you not to use them and to find someone else who will take care of their customers with care as well as deliver equipment that will work.
(Added May 7/13) I've been a customer of ADT since 1995, that's 18 years. And the service used to be good. Now, I would never recommend ADT to anyone! Stay clear of this company, your house could be burning down and they would put you on hold and an hour later tell you that they could maybe answer your questions the next day or soon after. ADT has the worst customer service I've ever experienced, and that's saying something. The fire alarm was going off in my house for over an hour while I was on hold and treated very rudely by the support teams. One lady told me it was hard for her to hear me and told me very rudely to go outside since it was kind of hard for her to hear. I live in Iowa, its freezing, literally. After being hung up on numerous times, being put on hold for who knows how long, and being told that maybe I should try calling back tomorrow during normal working hours, I was beyond frustrated. They only started listening after I threatened to call my lawyer, then they suddenly became more amicable. I don't pay that much to be ignored while my house has alarms blaring so loud that I still have tinnitus. Once again, worst service, I'm currently looking to replace them.
(Added Apr 8/13) I am amazed at how poorly this company (ADT) conducts business.  I only wish I had looked them up on BBB before considering them.  That site shows 4,043 complaints in the last 3 years that were resolved with the BBBs help - 1,626 in just the last 12 months...(read the whole review)
(Added Apr 3/13) I love the low cost of the system and customer service, but don’t enjoy the fact that if I would've known their wireless signal is based off AT&T I wouldn’t have gotten the system. AT&T has very little to no service (1 or 2 bars) in my area, but ADT has tried their best and slowly the service has improved but goes out occasionally. When the service goes out the alarm system literally beeps every 5 seconds until it decides there is enough service again. I bought a $300 3G wireless booster for my 3G ADT system and waiting on it’s arrival in the mail; the only thing I wish would've happened is if ADT bought the booster for me instead of sending me a 2 month reimbursement check (which I am very grateful for)
(Added Apr 1/13) Actually, ADT is not our provider.  I called them and told them I wanted a quote on what services they could offer me.  The initial offer was outrageous, but the sales rep put on a manager who came down considerably on the quoted price.  Before they would send anyone out, they said they had to have credit card information and social security number...(read the whole review)
(Added Mar 28/13) I signed in July 2012 and was vandalized on August 29,2012.No alarm went off.  It was disconnected at the AT&T box. I was never notified my system was offline and the police was not notified of a problem (I was in the hospital at the time of the break in.)When I returned home September 4, 2012 and notified them they came out and repaired the system and put alarms on the damaged doors but never reinstalled my camera. I made sure the beeping was playing when I called them yesterday morning to notify them the new doors and locks were being installed and I would need them to put the door alarms back on.  When they finished the door installs I called ADT and they were to dispatch the service person.  I finally got called back at 7:50pm asking if I still wanted a tech and to be prepared to pay almost $270.00 for the service call which was supposed to be covered under the vandalism claim during regular hours. Now I am sleeping nights in a borrowed truck at a truck stop because my alarm system won’t work and I go back to the hospital on Monday without an alarm system and if I cancel the contract because they can't provide the service I will owe $2800.00.
(Added Mar 18/13) Buyer beware. I cannot compare ADT to any other alarm system provider, but let me assure you I will never choose ADT again. The Customer Service personnel either lie, or change service appointments without informing the client. Depending upon the problem, the alarm system may not work at all. Leaving you with no recourse, except to hear that they are sorry and there is nothing they can do - nor can you do anything...buyer beware
(Added Mar 12/13) Do not use ADT in San Jose. AFTER selling you a contract about how great rapid police response is, they sent us a letter stating the police will no longer respond due to too many false alarms. They have to have proof of something going on by a witness or phone call from you before they will come. Best part, ADT will now offer (at an extra charge) a patrol service that from the outside might help confirm there is a problem. What a JOKE. When I tried to cancel my contract, they refused. So i'm stuck with a useless unresponsive service that makes a lot of racket. Rapid response time, gone. If i'm incapacitated and unable to respond? Useless. Only way out is to pay out the contract in full. Thanks for pulling the rug out from under us ADT. It doesn't matter what is in the fine print of the contract, you are not delivering on what you are selling.
(Added Mar 8/13) We recently learned the communication lines of our system had been severed and we had no connection for several months. ADT did not catch that we were not connected, thus alarm wasn't functioning. We switched to a lower priced internet-based service. ADT is now harassing us to pay for the entire year going forward. We signed a one-year contract several years ago, but they say because we didn't cancel prior to the automatic renewal, we must pay for the entire year. So, they want us to pay for the months it didn't work and the entire year we won't be using it. Automatic contract renewals are unethical and illegal in some states!
(Added Mar 8/13) Be extremely careful if you decided to sign up for ADT service. Ask questions. Check everything they promise. ADT representatives use shady business practices but even more importantly their service is useless...(read the whole review)
(Added Mar 7/13) I feel kind of stupid.  I've been handing my money over to ADT for the past 11 years.  I guess I was just satisfied in knowing I had a security alarm system.  I never thought about it before until I had my windows upgraded to double hung double pane windows.  Of course, now I need to have ADT come over and rewire to my new configuration...(read the whole review)
(Added Mar 5/13) ADT pulse is pure garbage, so don't waste your time or money.  First they told me I could monitor cameras real time thru any computer - not!  No federal system will allow QuickTime because of security failures, not even my local library. Then I set the cameras to take stills every 5 min; now they cut that back to 30 mins.  The wireless cameras are pure junk and you can't recognize someone 10 ft away. No motion sensors on the cameras, no email of motion trip, pure garbage with 45 degree viewing area.  Save your money and get a rabbit to watch and protect your home - it would be just as effective.
(Added Feb 11/13) I had ADT for several years at an apartment.  Moved into a house, they came and set everything up and we did the contract like I had in the apartment.  They were supposed to be taking out quarterly for the services and did not do so.  So I received a notice that they were going to cancel my services for non-payment.  I called to speak to someone about paying the balance but wanted to cancel my services.  The customer services person I spoke to was incredibly rude.  Would not transfer me to a manager and I ended up having to hang up on her and call someone else.  Their tactics are very shady.
(Added Feb 11/13) An ADT alarm system was installed in my home before I bought the home. Three days ago, the alarm began going off several times/day and during the night. I was able to turn it off temporarily thru the keypad, but it continued to alarm at all hours of the day and night. When I contacted ADT, their operators insisted that no one from their company would come to my home to disengage the alarm unless I open up a signed contract with them (and paid for the service). I would advise anyone to think twice before purchasing any services from ADT that you may later decide to cancel.
(Added Feb 11/13) I was able to navigate the procedures for ending ADT service some four years ago.  To this date reflection on the experience was so painful I still can not forget the incredibly bad service and ADT's inability to communicate basic information regarding passwords, sub-dealers, etc. This company gives capitalism a bad name.
(Added Feb 11/13) I DO NOT recommend ADT security! I came to this site to post my horrible experience with ADT only to find many, many others have the exact complaints. I was originally with Brinks. My contract has long been expired but I remained with them for convenience. I had a few episodes of no response but it was always a false alarm anyway so I didn't get upset...(Read the whole review)
(Added Feb 11/13) i had this system installed months ago it worked 1 week, called and they sent someone out and the next day it still did not work. I had to take some paneling off the wall where the wires were and had to take off the wire we called to have it put back they sent two different people out both said they can’t do it, it had to be reinstalled it was just the wire that had to be put back up.  After many calls and having to pay for all those months without service i cancelled the order and took down the system, now they say they will sue me for the balance of my contract. They did not live up to the contract so why should I have to pay, they are so rude and they lie about everything it’s all a scam
(Added Feb 11/13) Scam!  They said it was month to month contract and had us sign yesterday and found out it is a 2 year contract!  Already charged account without any service and now giving the run around for the return!  Stay away from ADT Pleasanton in Northern Cali!  Salesmans name is Mark Richardson
(Added Oct 2/12) I have been an ADT Costumer for over 6 years.  I recently relocated and had to relocate our service.  The sale rep was horrible, but we stayed anyway.  We upgraded to the "pulse" package and was ok with that.  They informed us we would get a new touch screen panel and all the bells and whistles.  Well 3 weeks later they showed up to install and surprise surprise no touch screen panel.  The installer stated that sales always tells customers they get touchscreen panels with the system.  I called ADT and after 2 hours was informed that the pulse does not come with anything I was promised and that since we touch the key pad to type in our code it is considered touchscreen.  They were happy to upgrade me if need be for an additional $500 installation and equipment fee.  Then when I wanted to just cancel the installation I would be charged $795 for the early cancellation fee.  I hate ADT and will try everything to turn people away from them.
(Added Sep 7/12) When I bought my house, I agreed to pay off the Brinks security service for the previous owner.  I was told that I had to have my own contract and then was misled into signing a three-year contract with additional charges and equipment added that I didn't want.  I called ADT numerous times and was told that I had to wait out the three years.  My bank account has been auto-drafted for three years and then the payments continued after they should have stopped, I called again and was told I could cancel but the last payments after the three years would not be refunded.  I will never do business with ADT again.  I've asked around and have heard that there are reputable home security companies that have the integrity that ADT is lacking, so I will be choosing one of them in the near future.
(Added Sep 7/12) We have ADT as our alarm service provider (previously Brinks, until purchased by ADT).  We had quick response and excellent local service with Brinks. However, we have been without service for almost one week, for a problem that  ADT has already determined is with their alarm panel.    We reported the problem August 16, 2012. ADT has us on their repair schedule for the first week of September, 2012.  I know it is hard to believe a reputable alarm company would leave a customer without service for almost 3 weeks, but it's true.  They said they no longer have a dealer in our area; the closest is over 3 hours away. Not only that, they say we still have to pay for the service, as the alarm itself still sounds. The alarm cannot communicate with ADT, but they said the noise itself would scare the intruder away.   I just can't believe this.  But it's true.
(Added Sep 7/12) I would give ADT one star at most. My experience with ADT was really bad, they kept increasing the price of the service a little at a time ($2.7 extra here and there) and we ended up paying A LOT for a basic service. In addition, this company even though it tells you the equipment you get it is yours....you end up with a piece of equipment that can only work with ADT! When talking to them about this, they refused to "release the cell module" arguing that this is something they "just do not do"...why would they help you if this would allow you to go a company with much better rates (less than half the price!) Overall a VERY DISAPPOINTING experience and I would NOT recommend ADT to anyone...stay away from this company!
(Added Sep 7/12) ADT has the worst service possible.  I waited a month to get my security system fixed.  They said they would be here between 11-1 pm, I waited and no  one  showed. I Have been on the phone with them for hours with nothing resolved.  I am sooo upset and dissapointed.  I have had multiple problems with them in the past about my system.   There prices are outrages.  It runs between  40-60 dollars per month depending on the type of alarm system you get and it cost thousands for installment.  I wish I never would of gotten set up with them in the first place.
(Added Jul 5/12) Save yourself from dealing with a dishonest security company. When hiring a security provider - you need to make sure you're dealing with a company with integrity, which ADT/Broadview Security lacks. ADT increased my monthly rate. I called to cancel and they stated that they would lower my rate to match the same rate I paid through Brinks. After 3 months I noticed an even higher increase. I called to cancel and they offered to lower again as the first time was  only short term. I decided to just cancel anyways as I didn't want to deal with another shorterm offer that is not fully disclosed. ADT turned off my alarm within a day, but I've gotted billed for two months since it has been turned off. I called and the customer rep said that's in our agreement, I cancelled on April 11th so they charged me for a full of April, and 30 days is May 11th so I'm getting charged for another month! Basically, I'm expected to pay two months of service that I'm not getting. Hey, that's my hard earned money you're taking! Another word of advise - do not do an auto pay with this company, again, they are not to be trusted. They didn't even have my telephone number on record when I first inquired about the increase. A telephone number is linked to the account, so if it wasn't on record then it's possible the security service I've paid for was not even activated.
(Added Jul 5/12) After having ADT for 10 years I decided to get rid of them.   After 10 years mind you, we needed to add a sensor and were told it would cost us 100 for the sensor, and 120 an hour for the service call.  We found another local company that we are happier with and has better monitoring for 1/3 the cost.  But after 10 years, ADT has tried to now hound us constantly for a 250.00 termination fee.   Needless to say they can bark at the moon for it.  We are well rid of them.
(Added Jul 4/12) This company is not very efficient and effective. We've had work done on our home the past few months and the smoke alarm was set off from dust, etc. When you call them to tell them it's a false alarm, you get an automated attendant and a bunch of questions and choices about are you interested in  buying a system, or upgrading your system, was your system installed previously by (another company).  These questions and choices all come BEFORE, "IF YOU ALARM IS GOING OFF"..by this time about 40 seconds have passed and the fire department has been dispatched.  This happened to us 3 times in 6 months!  When I questioned their phone system, all they say is "sorry"!  Today they told me that I didn't have smoke detectors in my home!  I have 4 of them (hard wired)!  I'm switching to another company very soon!
(Added Jul 4/12) I just received a call at 3:45 AM from an automated ADT service line that notifying me that I have a low battery.  I called the line back and at this hour only could reach the monitoring desk(the desk that you call if your alarm is going off, which mine is not).  I waited on hold for 6 minutes(what if my alarm was going off? 6 min would be an eternity).  The lady was professional but unapologetic, explaining the "system" is set to call automatically, but said she would set it so that a live person would call me in the future.  I ask her why it wasnt already set for that, or at least so the automated line would not call at 3:45 AM and she kept saying because that's how the system is programmed.  I EXPLAINED IF MY SECURITY SYSTEM IS NOT SMART ENOUGH TO PROGRAM THEIR SYSTEM TO NOT CALL ME ON A LOW BATTERY AT 3:45 IN THE MORNING THEN I NEED A NEW SYSTEM AND ASKED IF I WAS ON CONTRACT AND SHE TOLD ME I WOULD HAVE TO CALL THE SALES DEPARTMENT DURING REGULAR BUSINESS HOURS, I GUESS BECAUSE I WOULDN'T WANT TO DISTRUB ANYONE IN SALES AT 3:45 AM IN THE MORNING.  She just didnt get it at any point in the conversation, so I'm cancelling my service.
(Added Jul 4/12) Do not use ADT in San Jose. AFTER selling you a contract about how great rapid police response is, they sent us a letter stating the police will no longer respond due to too many false alarms. They have to have proof of something going on by a witness or phone call from you before they will come. Best part, ADT will now offer (at an extra charge) a patrol service that from the outside might help confirm there is a problem. What a JOKE. When I tried to cancel my contract, they refused. So i'm stuck with a useless unresponsive service that makes a lot of racket. Rapid response time, gone. If i'm incapacitated and unable to respond? Useless. Only way out is to pay out the contract in full. Thanks for pulling the rug out from under us ADT. It doesn't matter what is in the fine print of the contract, you are not delivering on what you are selling.
(Added Jun 5/12) We recently learned the communication lines of our system had been severed and we had no connection for several months. ADT did not catch that we were not connected, thus alarm wasn't functioning. We switched to a lower priced internet-based service. ADT is now harassing us to pay for the entire year going forward. We signed a one-year contract several years ago, but they say because we didn't cancel prior to the automatic renewal, we must pay for the entire year. So, they want us to pay for the months it didn't work and the entire year we won't be using it. Automatic contract renewals are unethical and illegal in some states!
(Added May 23/12) ADT has horrible tactics. I was out of contract and canceled my service with ADT when I moved and was not told about their relocation services. I'm sure they want you to just pay to have another system installed at your new place. I wanted to compare companies and prices, but ADT gives you a "deal" if you sign with them during your phone call. A system was already at the new house that ADT said was too "old" to connect to. I was quoted $1000 for a new system and accessories and $48 a month. They try to sell you lots of things you don't need!! When I noticed they were using the same "old" equipment, I told them to get their stuff and go!! I could never reach anyone in corporate but I was lucky because I had not signed the contract. I lucked out with a local company who activated the alarm using the current system. We were told that it was a really good system. Our options were to pay $38 a month with a 3 year contract, then payments go down to $20 a month because the equipment would then be ours. We took the cheaper, prepaid option of $450 which covered activation and one year of monitoring!! After the first year monitoring is only $30 a month or $180 a year prepaid! The salesman told us that any alarm company should reduce your monthly fee after the 3 year contract because the contract is for covering the cost of equipment. After that, you should only pay for monitoring. I tell everyone I know about this because ADT will keep charging you and you'll pay for your equipment over and over
(Added May 23/12) Poor customer service. Please see below the copy of an email sent to our ADT sales rep:  Max, I do not have any additional emails to support this claim. We spoke after the last email and I again told you that we did not want the service agreement. I have also spoken to several people in your customer service department regarding this to no avail.  Because of a lack of customer service on ADT's part this problem has escalated to the point where they will turn off service by May 1st if the service charges are not paid. Since we are locked into a contract with a 90% early termination fee it is not financially prudent to not pay the balance due. Perhaps this was your game plan all along. Be rest assured that I would never enter into another agreement with ADT nor would I ever recommend their services to anyone. Your lack of support is most definitely not appreciated.
(Added May 23/12) I have been with ADT going on 11 years. I had the system installed because of a psycho next door neighbor (they have since moved - thank God) and this system has been my life saver not to mention my peace of mind. Unbiased - I am completely happy with them. Their response time is excellent and their customer service has always been prompt with helping me with billing questions, referrals or upgrades to my current system.
(Added May 17/12) I have had ADT since August 2003 and love them! They call immediately when the alarm goes off. They are very responsive. They come out quickly to change batteries. I have never had any problems with them. Just wish they were a little less expensive. 
(Added May 17/12) I have been an ADT customer for about 23 years.  Four days ago I had the Pulse video monitoring system installed.  After the experience I would recommend that you run as fast and as far you can from ADT.They are selling a "half baked system" far from being redy for marketing !They try to blame it on everybody and everything,including my internet, which is fine. So,my advise is: run,run,run...
(Added Apr 30/12) I was a former Brinks customer. ADT took over Brinks as all know. I tried to cancel service because of financial difficulties. They told me that I would now get 3 months free to keep service and thereafter drop the rate to $19.95 per month. The 3 months free was fine, but the next three statements reflected the original higher rate.  I then cancelled the service. They require a 30 day lead time to cancel (which is ridiculous). So they are asking me to pay the 30 days plus the higher rate they charged me for 3 months instead of the new lower price. After talking to a manager they did not honor the $19.95 rate and said they never told me that I would get a  new $19.95 rate. This is deceptive.  I tried to discuss and lay all the history of events out for them but it didn't matter.  If they pursue collection I will send a note to BBB and Attorney General of Texas for deceptive trade practices.
(Added Apr 30/12) Been with ADT 7 years.  Paid $8500 for entire instal at my home.  I pay them a bit over $250.00 every quarter.  I have an insurance plan for all the hardware etc.  Yesterday evening the system started to crumble, RIF fried out, not touch pads show other hardware is burning out as well.  Spoke to ADT unable to send out service until 4/19.  Meanwhile no security at my home.  (Their have been 3 attempted break ins in the last 3 years.)  They are arrogant and rude and couldn't care less.  BEWARE OF ADT SERVICE.  THEY WILL TAKE YOUR MONEY AND LEAVE YOU ON A WEAK LIMB!    On Monday 4/9 I will call in a local company who specializes in Honeywell to pull out and restore my service.  My monitoring will go the new company as well.  ADT will lose about $1100.00 a year on me for their poor service.  These companies do not want to pay employees on weekends.  Its all about making a buck and paying the CEO's millions of dollars to destroy customer service and pare down the business!!  BUYER BEWARE!!!!!!
(Added Apr 30/12) I have had ADT for since 1976 with our first home because of the connection to USAA.  I'm switching to a local company because of extremely poor customer service.  They wanted to charge me for two trips to our home to install additional door and fire alarms.  They did not ask why or if I needed additional equipment, when they did not have the firearms with them they wanted to charge for an additional service call. Sorry, I'm gone, they have not called for an alarm going off for several years.  No service and no customer care, for them they have gotten to big and it's all about the money.  So long.
(Added Apr 25/12) I have been an ADT Customer for 6 years.  I moved a year ago and thought I was just transferring my service from one place to another.  Little did I know, it renewed my contract for another 3 years.  Now I am moving and I will not... have an alarm at my new place.  ADT is charging me $932 to cancel my contract.  They did not install the equipment in this home, all they did is transfer the monitoring from my old home to this one.  I was told when I transferred that it was a transfer of service.  When I called today I was told that I was locked into this contract and that this was explained to me when the technician came out to set my service up, which consisted of him making a few phone calls and collecting a check from me.  I promise, I will never use them again, I will see to it that no one I know ever uses them again.  The power of Social Media.  I will cost them far more than $932.
(Added Apr 24/12) We brought a home in Florida in 2010 which had a disconnected ADT system, so we called them to activate it. We are still living in Pennsylvania which is why we wanted the system turned on. Today the alarm went off. Our neighbor called us to let us know, but we received no notification from ADT that there was a problem, and the police did not come to the house. We gave our neighbors the access code to get into the house and the code for the alarm, but they could not turn it off. So, they called us back, we gave them the name of the technician who they called and he told them the only thing that could be done was to remove power from the unit - which they did. I called ADT and told them I wanted to cancel the service for non performance and was told it was my responsibility to test the system periodically, and that the contract could not be cancelled. What good is an alarm system that when it goes off nothing happens. Further what made it go off in the first place. Our neighbors could not find any problems in our house, so we now have a dead alarm system in Florida that we were supposed to check from Pennsylvania and we are still expected to pay the monthly fee. What a rip off.....
(Added Apr 17/12) I am moving out of state with 18 months left on my ADT contract.  They want the full remaining 18 months to be paid, won't negotiate a discount, and if they remove and install at the new location want me to either sign another 36 month contract OR $199 plus the remaining months on my current contract.   What a rip-off!  You would think they would give at least 10% off to pay in full... Do not recommend this company.
(Added Apr 17/12) I have been a loyal customer of ADT for 14 years.  My alarm had triggered a call for help twice - once while cooking (!) and I could not get to the pad in time, and once for an unknown reason while I was at work.  The second time while I was at work, my alarm went off and ADT called me at work before calling police or fire!  I couldn't believe it!  I was 30 minutes away, my pets in the house, and they called me at work instead of calling the fire department that is three minutes from my house!  Supposedly, this was 'standard procedure,' and they would change my account to contact fire department first in the future.  That was at least five years ago.  When I recently went to my account online for the first time, I see that it was never changed, and the names, phone numbers and call order were ALL incorrect!  I cancelled my account today, and after 14 years, they were not even able to cancel without charging me one more month's service.  Wow.
(Added Apr 16/12) They ignore you.  They will not return phone calls.  They will not resolve issues.  They say there's nothing they can do to help you, so you are left out in the cold.  I will never, never use ADT or recommend their service to anyone.  Their customer service is a joke.  I am their customer....I should not be ignored!
(Added Apr 12/12) The ADT service has been very accommodating to my home and prompt service has been given when the alarm system has sounded.  ADT is a very valueable service to have for your safety.  The service technician, Chris was extremely knowledgeable and repaired my service in a very short period of time.  I would highly recommend the ADT service for safety in your home.  Thank you for your service.
(Added Apr 12/12) I did not even make through an entire billing cycle before I decided to cancel my service with ADT.  First of all they lied about the price.  When I called to clear this up I was transferred a total of 7 times before reaching the correct department.  Basically nobody wanted to do their job.  When I addressed the problem they refused to admit fault for their forgetting to mention the additional fees.  Worst customer service I have ever experienced.
(Added Apr 12/12) I signed up with ADT when I first bought my home 5 years ago. The rate kept going up so I cancelled my service after a couple of years. Last year I received a letter offering a new low rate and accepted. I have now sold my home and called ADT to cancel service. ADT is refusing to terminate my service unless I pay them 490.00 dollars for a termination fee. Greed doesn't even begin to say what these people are all about. The moment the rep answers the phone you know your in for a battle just by the tone of their voice. Don't sign up for services! They will never let you go without a fight and every last dollar they can squeeze out of you.
(Added Apr 3/12) I just found out that my system with ADT has not been working for about 6 months.  They talked me into using the wireless feature because they said it's more reliable than going through the phone for service.  Well my alarm went off for no reason the last two nights (another problem) and I got no calls from ADT.  I called them and they said they have no signal from my home.  They said it's my responsibility to test the alarm.  Well unless I test the alarm nightly I have no way of knowing if it's working at their call center.  I purchased the alert button for my elderly mother since I travel a lot and she has been really home alone since the service I've been paying for does not work.  I now have to pay for a technician to come out and figure out why their wireless service is not functional.  They said they lease the service from the phone company so it's not their problem.  Well it's not my problem either and I'm paying them for service.  If they don't have a good wireless program, don't sell it to people.  STAY AWAY from ADT!  I won't be renewing and it's expensive to get out of the contract.
(Added Apr 3/12) A simple door to the control panel of my home is broken and ADT asks to send a technician to identify the problem!! My entire community has ADT hardware installed in our homes. I have never come across a more ridiculous scenario!! I have to spend close to $200 to have the system looked at, and all I need is a door. You sell the product but not the part, and if you do you charge an unfair amount... I despise your company and the treatment I've received! I will FOREVER tell this story to everyone interested in your services!
(Added Apr 3/12) I had Brinks for years and was very pleased with their service, then ADT took over.  ADT raised my rate rightoff the bat and then in Oct 2011 raised them again.  I found out that I was being charged $5 a month for an extended service plan but anytime I called about a problem I was told I would be charged if a tech had to come out.  I switched to another company on Jan 9th, 2012 and when I called ADT to cancel, I was told there is a 30 day notice required (there is nothing in any of the paperwork I have that says a 30 day notice is required). I got a letter dated Jan 18th that said I would get a final bill.  The bill came on Feb 24th and was for $77 for service up to Mar 14.  I called and complained about this and they cut it back to $44.82.  Watch this company if you have service with them and if you don't please stay away from them.  No one should have to pay $44 just to stop service on anything.
(Added Feb 28/12) ADT HAS NO IDEA WHAT THEY’RE DOING!!!!!!!!!!!!!!! I am having to deal with one problem after another and they care NOTHING about trying to fix any of it! DO NOT GET ADT!!! You would be better off having a kindergartener protect your home!!!!!!!
(Added Feb 28/12) We were previously brinks customers, who by the way had awesome service with no issues. ADT is now in charge of there accounts and let me tell you. This is a greedy company with terrible customer service. In the door they went up $2-$4 dollars on your monthly bill and the rep told me I was lucky as if they are the company that exist. Be- ware they lock your alarm units so that no other company can monitor them. Be smart stay away from ADT.
(Added Feb 28/12) Beware of ADT! They can steal your alarm system! Bought a new home with an alarm system installed - not an ADT system and not installed by ADT. We needed to add monitoring and ended up with ADT. After 10+ years, the monthly rate is just too much. Canceled it and asked for the code they used on my hardware - and they refused to give it. They claim even though it was previously installed, they don't have to give up the installer code they used. Effectively making it useless unless I have ADT. If it had been their equipment I could understand - but my hardware?? I'm trying to find a class action lawsuit to join against them. In this case it is theft.
(Added Feb 20/12) We are previously Brinks customer (we were very happy with their service) and ADT has acquired Brinks.  We added more sensors and signed another two year contract with ADT.  Now we'd like to get a quote to add camera system, so I called ADT and set us up for an appointment at 10am.  I cancelled all my appointments that Saturday to met with the representative at 10am.  It was 10:25am when i called ADT because he hasn't showed up yet, and I called back again after 10 minutes to check the status and the customer rep put me on hold and contacted Daniel and even his Sales Manager.  Unfortunately can't get hold of the two.  The customer rep offered me to re-schedule another appointment and I said I don't think so, do you want to reschedule another time to waste my entire morning and get upset.  I have never had a problem so far with our alarm system, but dealing with this kind of poor business, especially for a new or additional business from a customer did not seem to be their priority.
(Added Feb 14/12) Had a terrible experience with ADT customer service while I was shopping around for a home security system. My wife had called ADT earlier and they asked for the home address but she was not comfortable providing the address. Nonetheless, she was able to get some information from the customer service before I called again to close out the deal...(read the whole review)
(Added Feb 14/12) As a real estate professional I was contacted by ADT to refer my clients to this company. In return they would give me a $150 Visa gift card. My clients went with ADT, because of my recommendation, yet ADT refused to pay me my referral.  Somehow a company that misrepresents and uses people in such a way shows their true colors. Lying and cheating doesn't paint a very good picture. I plan to advise all my clients as well as my colleague's clients to stay clear of ADT!
(Added Feb 14/12) We were contacted by ADT that the alarm was activated in our house. We asked if they called the police as we were at least 40 minutes away. They said someone was on the way. They did not tell us that they do not call the police that it is against their policy to do so. All they do is call their contracted security company and that was the someone that was on their way. The security company was still not there when we arrived. We called the police at that time. It was 45 to 50 minutes that lapsed before the security people arrived leaving our doors wide open and our belongings missing. It makes me wonder if the thieves know that no one is going to respond so why not just take their time and get all they want. I can not believe that they did not advise us to call the police ourselves. What a waste of our money! I would never refer ADT to anyone.
(Added Feb 14/12) I needed my backup battery replaced. Called ADT head office and they sent a 'technician' who quoted $46 for the battery, $97.85 labour and $10 trip charge plus sales tax.  The technician took less than 15 minutes finished and was gone. He didn't screw the cabinet cover back and I had to do this myself.  Two weeks later I receive an invoice from ADT Head office for $284.42!  Avoid this company, both Head office and their dealer network. The real thieves you need to protect yourself from is ADT!!
(Added Feb 14/12) I had my house burned down over three years ago. Adt had no idea they were not even suppling service and have continued to bill me. I was told unless a break in happened they don't know there isn't a signal...Really for five hundred a year. I had well satisfied my contract and only asked to be credited for the last year that I caught the auto withdrawals. Of course they put the blame on me for not catching it sooner. Now I am on fixed income and it's just too bad for me. Do not use them. They couldn't even find my account by name only by bank account number,..Shame shame on ADT
(Added Feb 14/12) Our ADT nightmare began from the first day. My husband and I are expecting our first child and decided to get an alarm with smoke monitoring. We contacted ADT directly and a sales rep came to the house. We specifically asked about whether we needed to install a land line for the service. We stated that we were prepared to have a land line to not have any issues with the service. She recommended the wireless based Pulse system and assured us there would be no issues with the system being wireless...(read the whole review)
(Added Feb 10/12) Ironically enough, ADT was the very kind of thieves I should have been trying to keep out of my home.  They've billed me for four months (over and above my three-year contract term) where they have not been monitoring my premises.  If their response times for customer service issues are any indication on their emergency response time, being a burglar of ADT protected homes could be very lucrative.  It took me 9 emails, 2 phone calls and over 3 weeks to get a response from them.
(Added Feb 9/12) We had an ADT alarm system installed yesterday.  The gentleman who installed it was very nice. I felt in no way pressured to buy more equipment. He gave me his suggestions as to what he recommended, and then ended his suggestions with "It is your home, you have the final decision." He was very professional, took off his shoes upon entering my home, and did a very good job. He even waited until my husband got home from work to explain the system to him. I am very pleased with everything I have experienced so far and hope to stay that way.
(Added Feb 9/12) I have had such a terrible experience with ADT that I wonder how they will remain in business.  If you have a system up and running with them and it doesn't have any problems, I hope it stays that way.  Once you need service, they are the worst...(read the whole review)
(Added Feb 8/12) ADT is the most useless alarm company there is out there.  I had 2 burglary happen within 12 days of each other, I had 3 technicians from ADT come to check my monitoring systems in between and when I needed ADT to be responsive, they didn't even bother to call the police.  When I wanted to cancel my account I was told I had to pay $1000 in cancellation fees.  They've got to be kidding!  They can wait all they want for my $1000, they will not get a penny.  If you need an alarm system STAY AWAY from ADT!
(Added Feb 8/12) I was very unsatisfied with the service I received from ADT. When you call them for questions or help, the customer service agents are very rude and impolite. The company also refuses to honour it's guarantee that if you are unsatisfied within 6 months, they will refund your money. They won't refund your money unless there is an actual malfunction in the alarm that can't be fixed. Unfortunately, some things can't be fixed, like the way they treat their customers. If you cancel a contract with any other company, they will charge you a fee of a few hundred dollars. ADT Canada will charge you the full amount for the entire length of your term. I have been paying them $100 every 3 months for years for an alarm system in my old home that nobody uses. The worst is there attitude towards there customers. They will be very nice when they are pressuring you to buy and sign with them but if you have any simple questions or phone them, they will put you on hold for 40 minutes and speak to you like they think you're an idiot. They have been so rude to me over the phone, when I simply asked them if they could email me a copy of my contract, that I've actually cried. I never know companies this horrible could stay in business. I warn everyone not to make the terrible mistake that I did, and stay far far away.
(Added Feb 8/12) ADT - it's better to open a door to a thief than let ADT to your house.  ADT will try to have you on a contract for rest of your life.  They will make you sign a residential contract for 3 years...I thought I sign it for 2 and called 30 days in advance to cancel, I was sure my contract was signed for 2 years, the service rep. did not say anything that I have another year to go with them and early termination will result in $452.00 charge.  After a month, they sent me a letter that if I wish to stay with them I can and another letter to pay the outrageous penalty. When I called back to reactivate the contract for the remaining 1 year they said that that option is long gone and if I wish I can sign with them for another 3 years, or I have as Damian (billing dept. manager) 30 day to pay before they take me to collection agency.  All of them are arrogant, insensitive, corrupt ADT employees that want your money only. They are asking only for a class action lawsuit.  If we all discontinue with them they will have no one to rip -off.  ADT you made the top of my list of the most hated companies! 
(Added Feb 8/12) I moved into a new home in Brisbane Australia and had my alarm system replaced then monitored by ADT following a visit from a very professional sales person.  I wish I had chosen another firm and strongly recommend AGAINST ADT.  Not only did the new alarm system not work for 3 months, they continued to charge me, failed to return my calls, never answered a single complaint e-mail or call, technicians failed to turn up when they were supposed to and I had to chase them up - I could go on. And for this I pay a premium service ($50 per month) from which I cannot withdraw until the end of the 5-year time. I cannot even get a refund for the three months monitoring during the time the alarm system didn't work.  I feel like a mug - I chose a big, reputable firm because I thought I would be assured good service. Instead I am getting appalling service and I actually wonder what would happen if I did have a break in. Would they be just as hopeless?
(Added Jan 20/12) I was satisfied with ADT when I first got it but over the phone, a representative stated that my monthly payments would be around $35.99/mo.  Once the installation began, they said that my phone line wasn't compatible because its through the internet.  So they charged me $50/mo.  Everything was fine with ADT until like many Americans, we fell onto financial difficulties and I was unemployed for a number of months.  During this time, I came across a competitor of ADT and learned that they would only charge me $30/mo. regardless of my phone service being through the internet.  I also learned that an entire community dropped ADT and switched over to the competitor for a variety of reasons.  I haven't been able to pay my ADT bill yet, they continue to charge me and make threats to terminate my service if I don't pay up.  Instead of agreeing with me to make installment payments, they want it all in full.  They're out of their minds if they think I'm gonna pay them $1,000 just to get me out of my contract early.  ADT is fine as long as you play nicely with them but the moment you start asking about opting out of your contract early, they place you on hold for 13 minutes at a time, disconnect your call and give you the run around.  The first two times I phoned and asked about opting out of my contract early, I was given the runaround.  The ADT rep claimed I would have to contact that dealer that did the installation.  When I phoned the dealer, they claimed I'd have to call ADT.
(Added Jan 20/12) ADT has been charging me for months without monitoring my house. We had a phone # change and told the company of the new # and also canceled out contract effective last April as in April 2011 and today received a bill for for canceling service from 1/072012 to 04/05/2013, along with a previous service bill for last 4 months of 2011. One problem hear, I have never renewed any service agreement and as I stated before canceled service in April of last year, by the way that was after they had been charging me for not monitoring my house. If ADT calls on you to buy their service, lock the door and tell them to take a hike.
(Added Jan 20/12) I was with ADT for 5 five years.  At one point my phone started having problems.  They phone company fixed it.  About 6 months later I realized that the alarm system was only pretending to work and had been since the phone outage.  It was an easy fix, but why didn't they tell me six months earlier that the alarm had lost connection!  Surely, that would be an easy program to put in their system.  I should have cancelled them then, but I was still under contract.  Recently I moved and am not able to have an alarm in the new place so I called to cancel.  Apparently ADT makes contracts that require you to give 30 days notice.  No other utility type service (including cable) requires this and I did not think to pour over my contract and memorize it.  So, I had to pay for a month of service in a house I didn't live in (which doesn't have a phone connected in it for the alarm to work anyway!)  I emailed several times to express that I did not feel that this was good customer service and I didn't even get a response.  I would not use this company again and would not recommend them or any company the are affiliated with.
(Added Jan 19/12) I have just wasted a very important 45 min. talking on the phone with ADT account reps not listening.  We have ADT, my mother in law has ADT.  Her alarm went off when she wasn't home this morning and we are on the immediate call list.  We were not called to notify us but they left a message on HER answering machine that her alarm had gone off.  She called us to let us know and I called ADT wanting to know why we weren't called about the alarm.  I have been given more excuses than I care to discuss here.  No resolution.  No help.  Red tape and "reasons" why they could not help me.  Just arguments.  Meanwhile, mother in law could have walked into a burglary in progress.  ADT stinks big time with customer service and their snotty attitudes.  They get a huge disapproval on this matter and I will be calling them again to get to the bottom of it after we go to the other house and find out for sure what has happened.  We're on our way now.  Argggghhhhhhhhhhhhhhh. If this was a true emergency - I'm sure I would get the same attitude and excuses from ADT.  Customers - beware ADT.
(Added Jan 19/12) I had ADT since July of 2006. I have never had a call about my alarm going off. My friend have one and we are their secondary contact people. We get calls all the time for their alarm going off.  I have contacted ADT to check if my alarm is working, they do not know. It never went off.  My key pad also had "problem" light came on when I contacted them. They sent 3 different technicians to fix it but COULD NOT.  Each time they have to come I have to stay home to let them in that is more than 6 hours each time. Finally at the fourth time they offered to send a tech in one hour but I declined and cancelled the service with them. GOOD BY ADT.... Wish I read this comments and reviews earlier. For $34/Mo could do much better.
(Added Jan 19/12) I just cancelled my service with ADT. Had two false alarms in one night. They told me they could get someone out to check the system in 8 days! I asked why i would want a system that could not be used for 8 days and 3 different people in customer service told me that was the best that could happen. I will never use these guys again. This is emabarrasing for a company the size of ADT.
(Added Jan 19/12) I have been using ADT for years in my home and in my place of business. I have never had a problem that wasn't addressed promptly and to my satisfaction.
(Added Jan 16/12) I tried to close my account with ADT on 1/05/12 and a customer service rep told me the account was already closed. I was blessed I could remember that passwork after 11 years of being ripped off by ADT.  When I asked the service rep when they closed out my account while I was paying a quarterly fee, she put me on hold for 5 minutes then came back and said she made a mistake and the account was not closed.  I believe ADT was not monitoring my system but was accepting payment for when they were not providing the service. My home phone next to the alarm went out and the alarm had not been working. ADT did not detect something was wrong with the alarm.
(Added Jan 16/12) Jan 2nd changed smoke detector batteries. Afterwards the keypad started beeping.  Spoke to 5 different people in as many hours.  Not one could offer any advice or rectify the problem.  Finally the 5th person suggested having a service person come to my home. That was scheduled for Wednesday. Was I suppose to listen to a beeping alarm for two days?  The beep could be heard outside! After some pushing on my part, person #5 provided instructions on how to dismantle the system. Service rep. came out, did something, including replacing my new batteries, said the problem was in the key pad and main box and said I should call a sales rep. After the service rep. left I noticed my phones were not working. Tried calling ADT from my cell to see if the service rep. could return. I have now spoken to 8 people.  No security system. No phone. I wonder how they would handle a real emergency.  Think about it.  
(Added Jan 10/12) I Would Not recommend ADT to any one.ADT Has the worst custumer service.  Do not Use ADT.
(Added Jan 10/12) I was originally with brinks. I called feb 2011 to ask for better price for monthly monitoring. They told me I would get a reduced rate which is $22 month. They binded me to a 3 yr contract even when I told them I would be moving. The sales person told me that if I couldnt move the system with me they would cancel contract.  Today I called to cancel system as I am moving and do not need the system in the new house.  I was told I would have to pay $600. This company is rude and desperate for customers. I have decided to cancel the system at the new house as they have no cancellation fee and transfer the ADT system until my term is up in 2014. After that I will never return to ADT. They are a horrible company and I would not recomend them to anyone. Please do not get stuck in a 3 yr contract they are worse than cellphone companies.  I even asked to pay the original price of monitoring for 11 months, but they refused. Please find a different company for home monitoring ADT is horrible.
(Added Jan 10/12) (ADT Employee) I have been with the company for almost a year now. I work with both monitoring and taking incoming calls. It is very upsetting that I am reading these negative comments about ADT. We do our best to inform you of events that gone on at your home and to promptly take care of your problems. When people are complaining about "Our Patrol" units, they do not realize, their local police department normal chose those patrol units, no ADT. That is why when people call in with complaints about their patrol units, we recommend that you speak to your local police department. Also when you call in and complain because we have already notified the authorities, it's because that is what ADT is for! If we have already attempted to make contact with you, with no answers, we have to assume something is wrong and notify the authorities...And I repeat, that is what security means...
(Added Jan 9/12) Was great as Broadview with the Brinks system. ADT taking over has been a nightmare. Had to end our phone line, thus ending alarm system. We were told we could still use the system, just not the monitoring. Tech came out and turned everything off. Was told that as a Broadview customer that was correct but ADT does not follow those practices so no they would not follow through with what they said, even though their customer service rep said they would! Deceitful and dishonest. Will never use and will be switching my office account to another company asap.
(Added Jan 9/12) Lousy customer service AND when we installed a new front door, they told us that the LABOR charge to reconnect the door would cost $154 for one half hour plus parts.  We are cancelling .
(Added Jan 9/12) ADT came to our house and showed us different alarm panel options.  I chose the pulse system. Richard Castro was the salesman and showed me various pictures of panels and keypads.  When they installed the old, out of date, possibly used, old fashioned looking keypad I contacted Richard to find out why it was not the digital keypad that he showed me pictures of and said would be installed. He told me this old keypad would work better than the digital one.  This was an obvious case of bait and switch.  He agreed to upgrade them, but tried to raise the price by 50% from the original quote. Stating it was more work than he thought.  After discussing it, I agreed on a 25% increase in the price just because I had gone so long without an alarm.  My alarm was working before they came, but he sold me on the digital panels, the cameras that were never installed and being able to operate it from my cell phone.  you would think that when you use a big company they would have credibility and integrity.  This turned out to be a total scam.  We have been trying to get a hold of someone at ADT, no one will call me back.
(Added Jan 9/12) I hate Broadview.  I am cancelling my service with them; here's why: Our home has been vandalized twice in the last two weeks.  Broadview's policy is that they must make two verification calls before they will call the police.  Broadview has actually stated to me "that is Florida Law" - of which there is none.  When cornered they then responded that it is an ordinance for where we live.  I called ADT (Broadview's parent company) and they advised me that there is no such ordinance in effect for where I live.  I also verified this with the Chief of Police for my area.  I have told Broadview that the house will be vacant because we are going on vacation and that they needed to call the police department if an alarm was triggered... They stood fast on their policy that they must make two calls before calling the police... Since we're going on vacation, I gave them the number to the police as our primary contact number...  When we return, they will be fired, and I will find another company.
(Added Jan 6/12) ADT is the worst company to do business with. If you need help you do not know who to contact.  The advertising is a misleading. You can buy their equipment on line for $90.00.  When the installer showed up, he kept trying to get me to buy additional equipment at an inflated price vs what you could buy it on line. I assume the sale went to him and not who ever sold me the package.  When I had a complaint about my contract I was told too bad. ADT told me that the contract they had was the contract that I was bound to. Even though the rep changed the contract they could care less.  The rep that sold me the installation changed the contract when he left and I was billed for more then I agreed to.  After my first year, ADT raised my price. When I contacted them, I was told to read my contract. They could raise my price and there was nothing I could do.  Well I read the contract and found out that if I complained about the price increase they would bill me at my old contract price.  Bottom line. Do not use them.
(Added Jan 6/12) I had an ADT system with two different accounts since 2007.  I was required to have 2 systems, one for the house and one for the garage apartment.  I got rid of my land line in June of 2011.  It took me until December of 2011 to get them to finally ( I hope since I am still trying to get one of the accounts closed) close my accounts.  However, they still sent me to collections because I refused to pay the bill until they agreed to close my account.  I had never used their services, and forgot where I wrote down my code/password.  They will not close the account unless you have that password.  I could give them all kinds of other information, but it didn't count.  We argued back and forth for months.  Half the time I was talking to someone they didn't realize I had 2 accounts and kept getting them mixed up.  And what is this thing about having a machine call you and then tell you to wait for an ADT representative?  You wait and you wait...how long to they expect you to be on hold?  I had always told everyone I was pleased with their services because I had never needed them for anything.  However, the minute I need to talk to someone and get my account resolved it becomes very complicated.  I am thankful I never had to rely on them for any service.  ADT make a note...if people want to cancel their account, do not make them hate your guts by the end of it.  Bad public relations.  At some point, I may be in the market for a security system again, and I will not use ADT.
(Added Dec 19/11) I signed my contract with Brinks and was always very well taken care of. I could call and talk to a customer service representative and get any concerns addressed. Now I have moved to a house with an existing alarm system. Cancelling my current service with ADT has been a complete nightmare! My contract has been up for several months, so there's no issue there, but they are making it pretty frustrating to get out. I've never dealt with a company so desparate for your business that they all but refuse to let you cancel.
(Added Dec 14/11) I would NOT recommend ADT to anyone looking for a new home security system.  After nearly 20 years of complete satisfaction with Brinks, I have been very unsatisfied with the service and support of ADT since they bought Brinks.  I do not change business relationships frequently, but I have happily found a new home security company.
(Added Dec 14/11) Was a customer for 7 years and had to cancel a contract due to a physical office move.  Since we did not cancel the account during the 30 days before the automatic contract renewal (original over after 5 years) we were accessed a $400 early termination fee, while the quarterly cost was only $172.
Would not recommend ADT to anyone, scam to get out of the contract, even though the original contract was over in 2009.
(Added Dec 14/11) ADT told me that I would get a 100.00 visa card in the agreement we made. I had to send paperwork in with a money order which I did. I still have not got my 100.00 visa card. They lied! They make all kind of promises but don't come through.
(Added Dec 13/11) Worst possible service ever.  Company is always "experiencing a high volume of calls" recording, even at 3:00am and 5:00am.  No technicians in my city, Tallahassee, FL, so earliest appointment is in 3 weeks. Apparently, company doesn't care that I won't have a working security system for 3 weeks. Alarm is beeping constantly due to low battery (so, we replaced), but still on and off beeping in the middle of the night for two nights in a row.  Finally, dismantled system at 5:00am this morning and canceling service.  Advice: Hire people to answer the phones, hire technicians to service customers.  If not, your company will continue to lose valuable customers like me. 
(Added Dec 13/11) ADT has the worst customer service.  As far as ADT is concerned, I was just a number and monthly cash flow.  They would not fix a problem that had been occuring since installation (static on phone line) without charging for their service people to come out.  When I finally cancelled, they charged me about $500 for the balance of the term on my original contract.  I submitted explanations to their "End Of Term" group that supposedly reviews such issues, but they didn't care (they must have a lot of these issues).  I ended up fighting this and will probably have my credit dinged by them.  BEWARE - DO NOT USE ADT SECURITY!!!!!
(Added Dec 13/11) I have the ADT Premier Pulse system.  I got a good price on the install and the system worked.  Enjoy the automation.  I have added over a dozen of my own modules using the installer code.  Recently I wanted to expand the system with wired camera's.  To do this requires an IP server/decoder called the NV412A-ADT.  This unit costs about 75 dollars with an ADT analog camera at 250.00  installing one unit can be pretty pricey.  I had analog ADT cameras from another source (ebay) much cheaper.  My local ADT sales person seemed unable or unwilling to purchase the NV412's for me.  I posted on their facebook page and got a quick response.  They made me advise them of the camera model numbers before they would sell me the product.  My local sales person eventually just stopped trying to help.  I was shocked by that.  Bottom line, they wanted to do the install.  I don't need them to.  Since they were not going to make any money on the deal they didn't seem to worried about moving quickly on this issue.  Very frustrating.  I do love the system. 
(Added Dec 1/11) IF YOUR LOOKING FOR AN ALARM COMPANY I DO NOT RECOMMEND ADT....POOR SERVICE BEEN WAITING TWO WEEKS FOR A PHONE CALL NEVER DID..I HAD TO CALL THEM..I HAVE ONE THING TO SAY ADT SUCKS...!!!!!!   IM A REAL ESTATE AGENT AND I BE TELLING MY HOMEOWNERS..
(Added Dec 1/11) I have had ADT for almost a year now and it has been nothing but problems ever since.  They als have ridiculous charges for just about everything including servicing their alarm system which does not work...and I have to pay for it...
(Added Dec 1/11) My alarm system has not worked in over 2 months. Many calls to ADT only results in getting the runaround. ADT has no intentions of fixing my alarm, and has the gall to tell me I can not cancel because I am locked into a 3 year contract. So I am paying for their service that they can not give me.My next step will be to contact the Attorney generals office to have this company fully investigated.
(Added Nov 30/11) I have an ADT system install last year; I was hesitant to sign their 3-year contract, but I needed something installed...what a mistake-I should have followed my instincts and checked into other companies.  ADT is worthless and the system they installed, which I was told was "state-of-the-art" wasn't worth a darn.  The system couldn't even notify them if my landline was cut; which is required for them to recieve an alarm.  I would never recommend ADT to anyone and I'm in the Security business and people ask me all the time which alarm company I would recommend...and now I know which alarm company I would NOT recommed. There are better alarm companies out there who are more interested in your safety and not your money as ADT is...
(Added Nov 30/11) (ADT Employee) I have been employed by ADT for 3 years now and it makes me sick to see all these horrible reviews on the company. I work in the monitoring center and deal with customers on an Inbound and Outbound basis. When you have an alarm installed and it beeps...it is telling you there is a problem that needs to be addressed, it is not beeping to annoy you. When we call you its because something has happened at your location and we want to make you aware of it because you pay us to let you know what is going on. When you change your phone provider and you do not notify ADT like your contract says you should, we may not call you to let you know your system is not communicating because your system can't send us a signal to say its not working. It is not our responsibility to verify your equipment is working. Your contract states you should test your system on a monthly basis.  We are highly trained professionals so we don't appreciate it when you tell us we don't know what we are talking to.  Read your contracts before you sign them, that way you don't have to rant about crappy service from ADT when it really isn't crap service at all!!!!
(Added Nov 30/11) Recently met with a sales rep for ADT in my home.  She could never give me a straight answer on prices and at different price "levels" she would include or not include different equipment or features as it variously suited her (depending on how high she could get me to go on price).  "Oh, well at that price X is not included...for X you have to pay more." I still gave her a chance and signed a contract for a GE Concord system.  Well, the installer showed up a few weeks later and tried to SWITCH systems on me by telling me he was going to "give" me a better system at no cost!  What a swell guy!  Yeah, right.  When I insisted that he install the GE Concord that I paid for and signed a contract for, he said they didn't have it and it would be another month before they could get it.  He told me 99 percent of their customers get the system he was trying to give me instead of the GE Concord.  But when the sales gal came later that day to discuss the situation, she told me the GE Concord is so popular and they're putting that system in so many homes that they simply ran out and can't keep it in stock!  So someone is lying to me, and I don't deal with dishonest companies.  Bye bye ADT!  You breached the contract so we are DONE.
(Added Nov 29/11) I've been ADT customer for a little over a year and I strongly regret that I've not chosen another company. Although, they've been very prompt to inform me that alarm had gone off in my house, their "patrol officer" service had always been a total joke...(read the whole review)
(Added Nov 18/11) ADT bought Brinks.    Brinks was always responsive to alarm failures and did not overcharge for Saturday service, as does ADT. ADT is trying to create problems so they can come out and charge you $250 - 300 to fix something that should be free.    ADT I left after one month due to high costs of service over the former Brinks,  up to 2 months wait to change a low battery, and poor scheduling with practically no repair time availability that is convenient.  They are as bad as Time Warner.   I strongly recommend dumping ADT and go to Pacific Alarm where you will get good service.
(Added Nov 17/11) I was visited by one of your representatives this afternoon. I was very interesed in upgrading my system and excited about the offer.When they learned that I was already an ADT customer the offer was rescended and I was not able to be part of any upgrade of my curreent system. I think it is a very unfair way to treat your loyal customer of nearly 20 years. There should be some type of incentive for your present customers who wish to upgrade their systems.
(Added Nov 17/11) I have service with ADT security but the cellular tower almost never works. A technician has come to my house at least 3 times and still I get no signal. I called ADT to cancel and they want to charge me early cancellation fee even though it is not my problem that the cellular tower is not connecting. I called on 9/28/11 to cancel and they canceled my service on 10/28/11 stating that I have to cancel 30 days in advance. They are a rif-off. They want me to pay for something that is not working. I am not protected and I don't want to pay for it!  Please do not get ADT. You have to pay 75% of your monthly charge if you terminate contract early!
(Added Nov 16/11) ADT commercial account managers, customer relations, and service installation teams are unreliable and unprofessional.  This translates from the ground up and from the top down...(read the whole review)
(Added Oct 27/11) I was interrupted from making a meal with my family by ADT representatives selling the alarm product. I was assured, after I informed them I might be unemployed in a few months, that I would have 6 months to cancel. I then signed for my mothers house and mine. Within a month my job was no longer available to me. After two months of talking to managers and regional managers, my ADT took two months to cancel; however, they refused to cancel my mothers who is under the same account as mine. They are going to penalize me 75-100% of the contract cost. I was not informed of this until I got the bill by mail. Do not use this company.
(Added Oct 27/11) i had a service call a month ago to correct two items. one was my keypad, the other that one of the sensors came off a window. while setting an appointment the rep knew i did not have a maintenance contract and said i would have to pay for the service.  then she added that since my keypad was old, they replace them for free, wear and tear.  my keypad was 15 years old, became impossible to push buttons in cold weather. the tech came and left.  not only did the sensor not work, it now did not show up on my keypad as not ready. he also changed a setting without asking/telling me, that the phone call from adt would come in simultaneously as the alarm rang.  who can hear a phone over the alarm?  i have another appointment to rectify these problems.  meanwhile i received a bill charging me for the keypad and for the labor/materials for the sensor.  when i called and complained, they stated they knew nothing about replacing old keypads for free, and that i had to pay for the service call even tho it was made worse, not repaired.   they did say they would not charge for the second call but are insisting i have to pay for the first call meanwhile.   i do not think i should have to pay for a service that made a problem worse, i would pay after the hopefully successful second call.  and i am disputing the keypad as the rep volunteered that information. 
(Added Oct 27/11) We have been with ADT for over a year and so far we are satisfied with the service provided. We did have a problem with incessant beeping only to realise that the battery was running low. A technician rectified the problem within two days...(read the whole review)
(Added Oct 27/11) Just switched from ADT to Devcon.  ADT did not cancel right away, and refuses to cancel the billing for service they did not--could not provide, since the time their equipment was uninstalled.  I called and spoke to three different people at the company, and came away very dissatisfied with the way I was treated.  I wasn't blown away by their monitoring service, but they're customer service is some of the worst I've dealt with in years.  I don't know if there's better options out there, but given a choice, I would not go with ADT.
(Added Oct 16/11) After using the ADT alarm services for many years, our company moved & decided to use another alarm service.  ADT has continued to bill monthly for the service we  cancelled  September 1. They have refused to reach any settlement.   If you want a better alarm service, we recommend ASG Security which we are now using.
(Added Oct 14/11) I am an ADT customer, On October 11, 2011 I `received a phone call on my Phone from ADT, saying that my alarm went on, at my house in Northridge Ca. and I was in Hollywood for a business meeting. And I told ADT to send a police, to my house because I was far away. I arrived home after 45 min. and there were no police and no ADT security patrol car at my house, IT WAS ONLY ME. ADT security told me that police will meet me at my house before I get there. They even took my car description "so the police wouldn't be surprised by my arrival" so I drove home rite away. When I got Home my house was unprotected there were no police, or ADT security patrol car, they are very unprofessional and irresponsible when it comes to safety. This had happened before also, and the same thing happen last time. And thanks god that it was a false alarm. I should be promoted by ADT, because I was the first one to respond. When you choose a security alarm system NEVER CHOOSE I MEAN NEVER EVER CHOOSE ADT, they should only protect our cemeteries?
GO ADT GO!!!
(Added Oct 14/11) I have never been more deceived by anyone in my entire life.  I met with a sales rep, Michael, as I was interested in my first security alarm system.  I explained that I was new in the area, and that I would be living at the house for a Maximum of 2 years.  He explains all the benefits of an alarm system, and sells me the contract.  Service during the first year was par at best.  Fastforward, one year later, we are told my our landlord that we were being forced out due to chinese dry wall.  So we had to terminate our ADT service.  One week later, I am receiving a notice that I owe 578.96 for a broken 3 year contract.  I had no idea that the contract was 3 years, because it is written in extremely small font on the back of an 11 page contract, and the sales rep conveniently never mentioned this.  I submitted a dispute explaining the entire situation.  I never received any correspondance back, and now 4 months later, get a collection letter saying I owe $578.96.  This is a dishonest, misleading, deceiving, lacking any morals company.  My best advice is to never use them, and never trust their sales representatives.
(Added Oct 14/11) Where do I start? Well as soon as I expressed an interest about getting an alarm installed ADT rep was there in a flash the next day, contract in hand! We agreed on a 99$ deal and signed. Next I heard NOTHING!...(read the whole review)
(Added Oct 14/11) DON"T BUY THIS SYSTEM.  at 4:00 am two weeks ago, I started receiving alarm notifications that a communication issue was occurring.  I called their very rude customer service folks and they indicated their next available appointment is not for two weeks.  Meanwhile, my alarm goes off every night at 4:00 am.  Fast forward, today is my installation day.  Their window of opportunity is 12:00 pm - 5:00 pm (most working folk have to take off work to accommodate such a window), I receive a voicemail at 11:55 am stating that they can't come out because of an employee shortage.  I call customer service, they state - no more appointments for two more weeks.  Sorry you are awakened in the middle of the night, but we'll waive the service charge that we were going to give you.  What SERVICE CHARGE?  They stated that since I changed telephone carriers two months ago, the system probably hasn't been working and its my fault.  Hmm?  Aren't they supposed to be monitoring it????????? 
(Added Oct 3/11) I hope you have the time to read all the way through. This was truly a nightmare experience with a nationwide company. If you look for alarm monitoring services, look elsewhere. Every interaction with ADT was a huge disappointment, from sales to service, and in particular John F. with the Customer Relations department turned out to be a liar of epic proportions...(read the whole review)
(Added Oct 3/11) ADT Security Systems is a despicable company. They use entrapment to force my company into long term contracts. We signed a contract for a monitoring service in 2007. We moved to a different location in 2010 (across the street) and asked ADT to relocate our service (at that time our contract was already based on a yearly renewal-basis)...(read the whole review)
(Added Oct 3/11) ADT will REFUSE to cancel your service.  Even after you move and send numerous letters to cancel, they will continue to bill you.  If you do not pay theese bills for security on a home that you no longer even live at, ADT will turn you into collections while continuing to send you new bills.  DO NOT get involved with ADT.  They will never let you close your account!
(Added Sep 27/11) Hello, more than 10 years ago I was also Thrown under the Bus due to the company we first had ALSO being BOUGHT OUT by ADT...so after being with 2 OTHER co'S being Both bought by ADT...we were FORCED to go with ADT...(read the whole review)
(Added Sep 23/11) ADT is a HORRIBLE company.  No wonder they were able to buy Broadview, because they rip their customers off!  I thought I was enrolled in automatic bill pay on several accounts with them, but it turns out one account was not, but they never called me about it.  Instead they terminated the account so that I had to be 'reconnected' (to avoid a high early termination fee) and enroll in a brand new 36 MONTH contract!  When I only had 14 months left on my own contract, because they don't allow you to pick up where to left off, because it BENEFITS them tremendously! So their philosophy is if you are a "bad" customer, they revoke your contract, and sign you up all over again for 36 more months, because they want to keep you, hoping you mess up again, so that the termination fee and penalties are bigger for them on a 36 month contract!  Complete thieves!!!
(Added Sep 23/11) I paid to have 4 security cameras and related equipment installed on my premises. Three of the cameras were installed outside to capture activity around my building. The deceitful salesman wrote down that I was to have 4 color cameras installed and never indicated to me or on the contract that these cameras would not operate at night in no light or low light conditions. The cameras are useless at night! He quoted me $175 per camera to upgrade to cameras with LED functions intended to operate at night.
(Added Sep 23/11) I have had ADT alarm services now for 28 days and could not be more unhappy. First, I had to pay over $250 for installation, even though I had a coupon for $99 installation. I was told that was for a very basic system and since I wanted my windows and doors covered and not just a motion detector that I had to pay the extra costs. I agreed and I wrote the installation tech a check for $250 which is what he instructed me to pay. 3 days later, a withdraw shows up on my bank account for $291.99. I called my bank and asked how it was legal to draft an amount out of someone's account different than the check they were written. The banks only response was that this is a legal "grey area" but that it is absolutely not ethical. I then checked my bank account days later, to find out that ADT had now cashed my check for the original $250 it was written for. This caused my account to overdraft and when I contacted ADT, I was told that they would refund the money within 5 days. I have now been waiting 15 days with NO REFUND. When I call in to inquire about the refund status, I am ALWAYS told that I'll be given a call back once they can research the problem and I am NEVER called back. This company is an absolute NIGHTMARE. After all of this, I asked how much it will cost me to cancel my contract and they want $1,000.00!!!!!!   I cannot believe that I'm now stuck in a 3 year agreement with such a terrible company. Please learn from others experiences and get alarm services elsewhere. You will regret doing business with ADT.
(Added Sep 20/11) We bought a brinks service wiring and all with the required monitering. After the required montering was over we cancelled the monitering. A ADT saleman came to our home during dinner time and would not leave when asked to. He was bold enough to come to our front window to talk to us while we ate. He was almost impossible to get to leave. He stole our brinks sign right off our front yard. He came back to our house tonight and did the very same thing, disturbing us at our front window. My husband went to the door and recognized him. My husband stated you stole our sign and he admitted it This infuriated me all over again, I felt violated. I will never purchase anything from this company. He told our neighbors our house was broken into in an attempt to sell them a system, he is a theif and a liar.
(Added Sep 20/11) First when the installer installed he was great! But then the billing came. I asked him to bill me on the 15th, which I was billed on the 1st of every month, which was fine. But now this month they are trying to bill me the first of the month and the fifteenth of this month. I called to say there must of been a mistake but they just gave me an attitude that ADT bills for the first couple of months and they just started the billing cycle,except its been more than a couple months more like 4 months. And  even those my name is under the billing they cant talk to me about this as it is under my dads name which he has called 5 times in the past to give me authorization but that only works for that second not even instance as he had to call 5 times before they could install it and then it goes right back to the same old I dont have authorization. First of all they never told me that I would probably get billed 2x in one month when it swithced over so i could be prepared for it but no...they are a SCAM because they probably wont keep record of it or hope forget about it in the next three years and second they cant get there records straight. If you want to deal with some pain in the butt company for your alarm system then use them otherwise go somewhere else.
(Added Sep 20/11) Just in ABSOLUTE agreement regarding the high pressure sales tactics mentioned by others posting.  It was the first company I called shopping for securit systems.  I didn't want to commit to anything because I was shopping around and they reassured me if I changed my mind it would be easy to canceland get a refund of my installation payment.  NOT!!! There was a wait to get through to the cancellation department and the the "manager" I spoke to was trained to apply the high pressure tactics as well.  She try to envoke emotion "I guess you don't want you family protected" sort of responses.  I will be clear that I think I will recieve my refund but if you are easily pursuaded by these sorts of tactics call them DEAD last! My opinion is that by paying their high monitoring prices your are essentially paying a very high price for your equipment.  Probably the most expensive way to purchase and get equipment installed.  Call some local licensed installers directly and get their recommendations.
(Added Sep 20/11) My (elderly) father had an ADT security system for 5 years and never learned how to use it. After setting off the alarm while trying to learn to use the system, he decided to cancel his "contract". Unfortunately, the "contract" was indefinite, and the company wanted an exorbitant amount of money to cancel. Basically, ADT took advantage of an elderly man on a fixed income who couldn't afford to continue making monthly payments.  After my father passed away, my happiest task was to call ADT and CANCEL my father's contract, explaining he had passed away and wouldn't require their services any longer!!!
(Added Sep 19/11) Worst service I ever had, 6 months after installation, the false started at middle of the night and after calling 800 number, they wanted to charge hefty price to come over and trouble shoot. I told the sale woman I only needed the service for 2 years taht i was going to travel alot and when after two years with lots of dissatisfaction from the service they provided, I try to cancel my account, they said I owe them another $450, since fine prints said my contract is for 3 years, even though I told the sales person I needed the service for only 2 years. before you know the collection agencies started to herras me and my wife. This compnay is the worse security service and stay away from them. They are bad news.
(Added Sep 18/11) I live in Austin Texas and was forced to evacuate due to Steiner Ranch fires.  While in out of town the power was restored to my home and I called ADT to have them alarm my home.  To my suprise, they refused to alarm my home unless I paid them $35 dollars.  Thats the way to take advantage of people.  Needless to say they are gone when I get back home to check on my home today.  With 4500 homes just in Steiner Ranch at $35 per home thats a lot of money you do the math.  ADT takes advantage of its customers.
(Added Sep 17/11) ADT advertises “Always there.’ In our experience it certainly was.  We moved into a rented home. Our landlord had house for a number of years, during which time she had contracted with ADT for an alarm system. We told her we didn’t want the alarm so she contacted ADT to have it removed. ADT convinced her to leave it behind and permit ADT to install a new alarm system in her new home...(read the whole review)
(Added Sep 17/11) SORRY,SORRY,SORRY, WHAT CAN I SAY. BEEN A LONG TIME CUSTOMER WITH ADT LIKE OVER 10 YRS. AS YOU KNOW OVER TIME HINGS CHANGE AND GET BETTER. WELL WHEN IT COMES TIME TO UPGRADE WITH ADT THEY WILL HIT YOU HARDER THAN THE GAS OR FOOD PRICES.THEY DON'T TRY AND WORK WITH YOU ARE NOTHING JUST SAY THEY WANT OVER $500 TO UPGRADE. AND I SAY BEFORE YOU DO THAT JUST LOOK AROUND BECAUSE IT IS OTHER COMPANIES OUT THERE WITH FREE OR UNDER $100 TO PUT IN THE SAME SYSTEM IF NOT BETTER THAN adt. ALOT OF YEARS WITH THEM TO BE TREATED LIKE NOTHING WHEN NEED TO UPGRADE. OH YA IF YOU GOT A SYSTEM WITH THEM AND YOU NOW HAVE DIGITAL PHONE SERVICE. YOU BETTER GET IT TESTED CAUSE IT DOESN'T WORK WITH DIGIATL PHONE THEY WILL NOT TELL YOU JUST PAYING EVERY MONTH WITH NO MONITORING AT adt...
(Added Sep 17/11) Canceled my service 5 days after billing cycle ended. Was charged for whole month of service that was not provided. Was informed they do not pro rate bills. While it is only $35  for me think how much they make off the thousands of others. This is the only company I have ever seen that does not pro rate their bills.
(Added Sep 1/11) We installed an adt PULSE system and have had numerous issues.  The remote light switches don't work with 4-way light switch setups.  The thermostat is very difficult to set up.  The local service people and the 800# people do NOT undersand this system and have been useless.  After four service calls it still doesn't work properly.  Now we've had a power outage for three days and got no call from the monitoring center that our system was down.  Turns out you need to add a cellular backup in case your phones are out.  We would NOT recommend ADT to anyone.  If we hadn't already invested so much effort we'd have them pull it out!
(Added Sep 1/11) We had an ADT security system, then moved to an area where they do not cover. We wanted to transfer the system, but they could not, yet they want $400++ in cancellation fees!!! We do not want to cancel. We knew when we signed up that we did not need the system more than 2 years (less than the 3 yr contract). The sales rep. assured us that this would not be a problem (the service would be transferred or the fee waived), i.e., she lied to us. Further, they informed us that they could not forward our bill and could not send it via email - what's up with that? Google "ADT lied", we are not alone. ADT protects your home while stealing from your wallet. Sorry, but I cannot recommend ADT Security.
(Added Sep 1/11) Left hand doesn't know what right hand is doing. Accounts function ignores letters and send out invoices, final demands regardless. Battery failed, alarm went off, engineer called - sorted within two hours. But the battery was not two years old. I questioned why I paid £130 each year to ADT for 'service'. I've hearing difficulties, so prefer not to use the phone and prefer to get things in writing - four ignored letters drove me to finally sending emails - response in a few days (what do people do if the have no email?) - and a labyrinthine dialogue ensued with Customer Accounts in Kent whereby, after consulting their engineers, Customer Accounts agreed to waive the call-out and battery replacement charge of £125, but ADT's Accounts function in Manchester continued to send me increasingly threatening invoices and offensive letters suggesting that I had not contacted ADT! Me not contacting them? If only I could! I've terminated the contract.
(Added Aug 28/11) I need to tell as many folks as possible to be aware of ADT's high pressure sales and more!!
Not only are they high pressure but they out right lied to me!!!When I made them responsible for a lie about the remotes they had to come out and check the system.When they did, they found that my smoke detectors were not hooked up. I would have been paying for a service for 2 years that was not working and placing my family in jeopardy!!! They are not to be trusted!!!!

(Added Aug 28/11) We signed up for the $99 3-room security system. The service tech that installed our system was more like a salesman than a technician. By the time he left I had written a check for $1190.81 and signed a contract for the monthly service provided by ADT. We then started pricing other systems. This system would be a nice system but did not secure our entire home for this price. In order to secure our entire home the cost would have been around $5,000. We found a less expensive system that we could install ourself with the same features. So we decided to cancel this within the 3-day time frame. So here's my complaint: the day we called for the $99 installation $107.56 was taken out of our checking account. The day the installation was done another $83.31 was taken our of our account. Then 2 days after I wrote the $1190.81 check that money was taken out of our account. I should have cancelled the payment of the check but thought that by cancelling the service our money (all of our money) would be deposited into our account! Was I wrong! Here it is 2 weeks later and today ADT informs my husband that the money will not be reimbursed until September 2nd (30 days later). I'm really hoping all of my money is reimbursed because we returned all of the system, including the $99 equipment. We'll see...this system is too expensive and they do not return your money the way the installation/salesman makes you think they will. Nothing was mentioned about the reimbursement taking 30-days!
(Added Aug 28/11) Reasons not to buy ADT. I purchased my alarm originally from Brinks (no complaints) whose contracts were bought by ADT, when I tried to cancell I was given the run around billed for agreements I that I had not made and threatened with collections on those agreements.  Now six months after finally getting the monitoring cancelled ADT sent a signal and disabled my whole system.  When I originally purchased the alarm from Brinks I was assured that after the initial contract I owned the system and was free to use it un-monitored or use another monitoring company.  Now my alarm keypad won't arm and only lists the ADT 1-800# on the screen.  ADT wants $500 tp "allow" me to use my system un-monitored or with another company.  These people should be prosecuted criminally, avoid them like the Taliban.
(Added Aug 24/11) Our system was draining the battery on our system.  I called and two weeks later I was able to get a service call, which I had to take off work for.  The battery drained again in less that 48 hours.  I called and it was another two weeks before I was able to get another service call, taking off work again.  Once again, the battery drained.  I called can explained that I would need a weekend call, the rep said that she would request our local office to call us when they have an opening or she could schedule me for another two weeks out.  I asked to speak to a manager, Brandon in TN.  He said that there wasn't a local number for me to call, I would need to wait for them to call me or I can take off work again.  I asked for a credit since I haven't had service and he said that we could talk about it when my service is running agian.  Unreal..I've been a customer for 15 years!!  Serivce from ADT is horribble and unprofessional!
(Added Aug 24/11) If I could give no stars at all I would! We have had ADT for several years and we called to cancel our service. The rep asked why we were cancelling and I said because of cost. He said if you get a discount currently on your homeowners for security you will now lose that discount for not having an alarm service. I mentioned that we hired a new company. The rep asked the name of the new company and I politely declined to supply the name. He demanded to know why I woudn't supply the name of the new company. He said if I didn't supply the name of the new company than I would have to cancel my policy in writing and that if I did supply the name of the company than they would allow mw to cancel service over the phone. Then he attempted to bully me by saying "no one had ever refused to give him the name of the new company, or a reason for not providing the name. I said "I'm sorry this conversation is ended, I don't want to argue with you." and I hung up. The rep had the audacity to call me back to continue the argument with me! This company is extremely unprofessional! I have also filed a complaint with theAattorney General's office in Massachusetts.
(Added Aug 24/11) After 9 years as a loyal customer I called to cancel due to a move.  I was all set to continue with them until I discovered that from the time I called I would have to fax in 2 letters, submit a form and then still pay for service for 4 more months!  This was not in any contract I signed and was told that this is "policy".
(Added Aug 16/11) I called on 08.13.11 to get some information on ADT and their services. I was told everyone was busy and that someone would call me back on Monday 8.15.11. I also completed the online call back option and have yet to receive a phone call back from ADT. It is 8.16.11 and if ADT calls it will be a big mistake. I wanted to give you my business but obviously you didn't want it. I will be taking my business elsewhere. It's ashame that your company has so many bad review, looks like the president of the company needs to re-evaulate their employees!
(Added Aug 15/11) ADT is the worse company in on this earth and I do think that the FBI and BBB should investigate ADT business practices. One of their high presure sales lady knocked on my door and talked me to getting their useless alarm that never worked. I called ADT and told them that the alarm was wakeing u up at night. I was rudely told that someone would contact me and they never did.  I asked the sales lady if there was any long term contract with the service and she told me "Now, you can call us anytime to cancel the service" She said the three year contract on the form was just there because it is an old form. Well, I called ADT to inform them that I was moving overseas and that I no longer need the alarm. I was told by a rude person "You are on contract for three years if you do not pay 75% of the contract value, we will screw-up your credit. I will advice everyone never to do business with ADT. The are rude, they lie to you, their service sucks, their customer service sucks.
(Added Aug 15/11) rude telephone reps.  i call to cancel my service at a rental as the rental house had sold.   they refused to terminate service i had had for 7 years with 8 days notice (day house was to close) and were insulting.   when i requested to speak to a supervisor, the rep refused to allow it.  i never intend to use adt again in any property i own.
(Added Aug 15/11) Do not use ADT.  I had ADT for 12 years. Never have they offered any upagrdes to their system - even with major technology changes (I had a hard-wired phone line system).  I once inquired about additional sensors, but the cost was completely outrageous - both for the device & install, plus the increase in monthly monitoring cost !
Three months ago, I had a saleman of a competitor to ADT come to my door. Based upon the ADT sign I had outside, this person told me the model number of the control panel I had and how he could disable it within 20 seconds. I agreed to allow him to try.  I armed the system, he open my front door, followed the control panel beeping to it's location, popped-off the cover and unscrewded a couple of wires and for three months ADT has never called about their system being disabled.  I have send two cancelation notices to ADT, which they claim they've never recieved.  They continue to DEMAND payment for services not rendered.  Essentially my house and family have not been protected for the last 12 years, and I've pay a considerable amount to ADT for false security.
Need to find a good lawyer to start a class-action suit against these rip-off artists.  Stay clear of ADT !
(Added Aug 15/11) ADT lied, cheated, and even kept my money.  The salesman told me great things about the company. The installers had no idea what they were doing and messed it up twice.  I finally got tired and demanded my money back which they ignored.  I finally went to the Better Business Bureau in Fort Worth, where the parent company is because ADT lied to me.  Then when I got a refund after several months, it was over $25 dollar short of what I paid originally.  It you use ADT you are stupid.  They are as unethical and low class a business as I have ever seen.  So very sad.
(Added Aug 15/11) I had ADT security system installed in Dec. 2010, in Oklahoma City.  I live alone . . .am seriously disabled, particularly with hearing.  Wear two aids which I remove at night to sleep.  REquested equipment for hard-of-hearing when equipment installed.  Was never provided.  Also requested medical pendant.  Never provided.  I have hassled with ADT service since installation.  Finally fed up -- now they want to charge me $900 fee for discontinuing service that they never fully provided.  State that I am breaking contract . . .NO!  They broke the contract when they didn't provide equipment that accomodates my hearing loss.  Isn't it amazing that the service reps state, "You aren't hard-of-hearing, because you can TALK!"  Ha!  I thing discrimination against handicapped is an issue as well as the poorest service by a nationally recognized company.  Can't afford to cancel, and receive no usable service.  Don't ever commit to ADT - no matter what!
(Added Aug 15/11)  I was an ADT customer for over 10 years until they pulled a "repair" scam on me.  I would receive calls every month or so saying they couldn't get a signal on the phone connection to them.  After a few tests, everything would be okay.  Then, a few months ago, ADT couldn't resolve whatever the recurring connection problem was and said they would send a repair person out.  I thought it was about time they fixed the problem because I was beginning to question whether I was actually receiving monitoring services at all.
The repair person fumbled around for a couple of hours and didn't fix the problem - but did generate a billing of $322.39 for the failed repair effort because he concluded the problem was in my phone network rather than ADT equipment.  They provided no cost estimate in advance of the work and never provided any details such as hours and rate per hour.
The thing that irritated me the most was that ADT agreed to "investigate" my complaint about the billing but wouldn't hear my side of the story.  Their investigation consisted of asking the repair guy if the bill was valid.  They didn't talk to me and wouldn't talk to me when I called to give my side of the story.  They simply said the complaint was investigated and the finding was that the charge was a valid charge. At that point it was a brick wall.  They didn't even try to do something to retain the business when I cancelled my service.  Funny, they give you all kinds of things to sign you up but kick you out without a whimper when there is a problem??
If anyone really wants monitoring, use someone other than ADT.  If a repair person walks in your door, require a cost estimate before allowing them to perform any repair activities.

(Added Aug 15/11) I signed with ADT to install a major alarm system in my house 3 years ago.  The term of the contract is to sign on with them after installation for 3 years.  However, a year into the contract, due to a dispute of an unauthorized charge ADT made, ADT cancelled the service, which I thought the service was just "suspended".  After some negotiation with the original sales rep, he pulled out another contract which he claimed that he had to do to "reactivate" the service.  Thinking nothing much of it, I signed the "reactivation contract".  This year, my 3 years with ADT is due.  I want to search around comparing rates to see if I can get a better deal.  When I tried to cancel with ADT, they told me I have another year to go.  After several calls to the sales rep, he finally called me back and told me that the "reactivation contract" I signed 2 years ago has a 3 year term.
This is not fair.  A reactivation contract should mean it continues the previous contract term, not resetting the clock.  This is definitely a con.
They have not been honest throughout their work.  They also have incompetent workers.  Some simple problems take so many trips and so much time to resolve and they charge by the man-hour.  They usually send 2 or more men to the job.
I am going to take legal action against them.  In the meantime, I hope no one else falls into their trap.

(Added Aug 14/11) my alarm been nothing but trouble from the day it was installed it has been changed 3 times and still not working correctly ! Going of in the middle of the night for no reason at all and ADT phoning our mobile numbers leaving a blank voice mail ! very helpful ! Very poor customer service all they say is just send a engineer out. engineer don't turn up when they say the will or when they do the spend most of there time on there mobiles ! What will happen next !
(Added Aug 14/11) ADT is the absolutly the worst company I have ever dealt with.  I can't stand them.  The change over the company and never even bothered to let me know. Then they sent me a noticed to say they were changing my fees from something lower to something higher when I was already paying a higher fee. I left ADT previousely and webt to Brinks and now I'm stuck with this crap again.  I called their company and the young lady who answered the pnone had the absolute worst customer service skills because everytime I asked her a question, she gave this as answer "well um I'm not for sure about that but this is what the computer says"  I mean what??? All you see is what?? Every time I have had to call them, it has been a problem and you almost have to cuss them out.  They are the worst.  Then I had to have my battery replaced; And even though I pay for protection service,  was informed that doesn't include changing the battery.  I would suggest that no one ever buy ADT.  Let's do the would a favor and put them out of business.
(Added Aug 14/11) ADT broke a window in my moms house while installing an alarm and will not fix the problem my parents spent like 2000.00 on the alarm and that was a lot you've taken advantage of them and will not fix the problem..   I am prepared to go to the appr. orginization with this matter my parents got the alarm to feel safe from robbery and youve done just such
(Added Aug 14/11) I AM A SENIOR CITIZEN, AND HAVE BEEN WITH ATD FOR 10 YEARS AND i AM COMPLETELY SATISFIED. HERES A SAMPLE OF PINTICLE PRACTICES
THIS YOUNG KID ABOUT 25 SEES THE ATD SIGN IN MY YARD, SO HE KNOCKS ON MY DOOR, WHEN I OPEN IT HE HAS THE AUDASITY TO SAY, WE PINTICLE INSTALLED ALL OF ATD SYSTEMS SOME YEARS AGO, WHICH IS LIE ONE. AFTER I TELL HIM I AM NOT INTRESTED, HE CONTINUED LIKE AN IDIOT, TO SHOW ME A PAGE OF DIFFENT SYSTEMS ALARM PADS AND ASKED WHICH ONE I HAD. A CRIMINAL COULD USE THAT SAME INFORMATION TO DISARM A SYSTEM, SO OF COURSE I DIDNT GIVE IT. THATS MISTAKE 2 THEN HE KEPT TRYING TO GET INSIDE MY HOUSE. HE SAID TO INSPECT THE SYSTEM, THAT MISTAKE 3. I SHUT THE DOOR AND CALLED THE POLICE COME TO FIND OUT PINTICLE DIDNT HAVE A PERMIT FOR DOOR TO DOOR SOLICITATIONS. SO THEY WERE ESCORTED OUT OF THE CITY LIMITS. THESE PRACTICES ARE OFFENSIVE, AND REFLECT VERY POORLY ON THE COMPANY.

(Added Aug 11/11) We are an auto repair shop, had ADT for about a week, an inadequate installation for our building and a serious lack of customer service has left us without an alarm for over 3 weeks and 3 rescheduled appointments at their leisure. With literally thousands of dollars worth of tools and equipment in this building over night, this is absolutely unacceptable. Also they have informed us that we will be paying for the repair to get the system running properly whether or not the issue was due to inadequate equipment for our building. Wouldn't recommend this company by any means.
(Added Aug 11/11) Here is what you can truly expect from ADT from someone who actually has an ADT system:
The salesperson was extremely knowledgeable not only about equipment to cover my home, but also other ways to better protect myself and my family...(read the whole review)
(Added July 4/11) I had ADT for about 5 years, and for almost a year of that, my alarm was not working. I did not have the arms' and legs' worth of money they ask for to come out and take a look at it and maybe fix the system, so I just waited, thinking that at some point I would get it fixed. I finally decided to just cancel my service, so on April 1, 2011, I called to do so. Come to find out, they had just processed a payment for $438 on my account for service for the following year. I had received no warning that they would be taking this money out of my account. This was a problem in the past, as well, but I was willing to overlook it since I wanted to keep the service. So they proceeded to tell me that I would only receive a refund of $402 because you have to cancel a month prior to when you want it cancelled. I wasn't thrilled, but I accepted this. One month later, I still had no received my refund. Somewhere between May 1-4, I honestly don't remember which day, I called again to ask about my refund. I was told that it takes a month to go through and that I would be receiving it in 5-7 business days. Today is May 24th and I have yet to receive my refund. I called to ask about it and was told that it takes a month to cancel and account and an additional month to receive the refund. Why am I hearing different things every time I call? Not to mention, every time I call ADT, I get shuffled around before I finally get to talk to the representative that can help me. Also, how is it that they can take over $400 from my account without warning, but it takes two months to refund it to me? I don't understand. I would not recommend ADT to anyone ever again.
(Added July 4/11) I received a call from ADT regarding a low battery signal for my alarm system. I would normally appreciate this call except that I received it on 05/28/2011 at 2:15 AM. I was instantly awake, my heart pounding as I assumed there was a real emergency. Very unprofessional of ADT.
St Paul, MN
(Added July 4/11) I have had ADT for 2 1/2 years with no incidents.  We were having new windows installed in our house, so I called the 800 number to ask them to come out and see what could be done about saving the window sensors.  The corporate guy said the local office would call me back that afternoon.  The local office waited six days to call me, and then left me a voicemail with an attitude like I work for them and they were doing me a favor by calling me back.  By then my windows were replaced and the window sensors had been forcibly removed (several wires clipped because they were inside the window frames).  I just called customer service again, and the guy said there is a $249 early termination fee.  So he transferred me to the service technician scheduler guy to see how much it is to reinstall the sensors.  This new guy says it is $130 for the first half-hour, and $31 for each additional 15 minutes after that.  If they had come out when I asked them like they should have, I would still be with ADT.  Now I am forced to pay the early termination fee because I cannot do business with this company.
(Added July 4/11) I recently switched from ADT after 7 years. When I called to cancel my service (finally!), the guy on the other end claimed he could not find my account. I kept him on speaker phone since at first I found it humorous. He put me on hold several times, coming back to the line just to say "hold on," literally not allowing me to even speak. I left the phone line open, wanting to know where this would go. As suspected, he kept me on the line - on hold - for over 1 hour! How disrespectful and unprofessional. And I have to say == that kept in line with the service we received those 7 years!! I am glad to be rid of ADT.
(Added July 4/11)A pushy annoying ADT dealer called and despite his annoying attitude, I signed up because I need it for my home insurance policy. However, I specifically said YOU WILL NOT CHECK MY CREDIT. He said okay, you can pay 36 months in advance and we won't check your credit. I don't want a credit check because I just arrived in the US from overseas and the last time I did so all the inquiries for gas, electricity, water, cable, Internet ends up dropping my credit rating by as much as 100 points.
When the installer arrived, he had my credit rating on the bottom of the contract. They had already checked my credit despite the fact that the annoying salesrep promised they would not.
And when I tried to raise this with the installer, he tried to assure me they ALWAYS check credit, it's company policy. When I said YOUR SALES REP PROMISED, he said he had to leave because he couldn't handle "rude" people. Seriously? Deliver what you promise and you wouldn't have rude customers.
(Added June 14/11) I have had ongoing problems with my system for over a year, constant trouble signals that would wake me at all hours of the night and whenever we were away we would get calls of trouble signals the entire trip. I had service techs come and fix the problem only to have the same thing happen again within a week on several occasions. Fianlly I cancelled the service and was treated so badly that I was in disbelief that any company could have such horrific customer service. I was also told I would be billed for the remainder of my contract, unbelievable! Just BEWARE DO NOT USE ADT THEY ARE A SCAM!!!!!!
(Added June 14/11) Don't trust them. They tell u that u have 6 months to cancel and that is a lie. I have been lied to since day one when I asked the sales person if I was signing a contract and he said no I could cancel at any time. Well I have been unhappy for a month now and tied to cancel and guess what.....I apparently signed a 3 ye contact and it will cost me about $1100 to get out of it. I am so upset. I have called the sales Mgr and told him I want out of everything with no fees and I am waiting on his decision.  Adt sales ppl will say anything to make a sale so watch out.
(Added June 10/11) I was never told that there was a contract with adt and the installation fees that the rep is charging or the company is false advertise.  I really feel like when I talked to the sales rep I just got riped off...  I only had the derived for the service for 7 months and now I owe thee company 1600....  does that make sense? And sending me to collections?  I was never told about the contract and the house is getting foreclosed.  I'm not sure what to do and need help.  Is there anybody there that can help me?
(Added June 9/11) I am completely dissatisfied with ADT.  Back in December out home was broken into and we were cleaned out.  ADT called my phone ten minutes after the alarm was activated and called 3 times leaving a voicemail twice and then contacted my husband before notifying the police. My thoughts where if you got a voicemail you would contact the police, but not in this case. We made it to the house before the police and everything was gone and damaged. Then on yesterday as my husband and myself were out of town our alarm went off again. The customer service rep told me the alarm was activated at 9:36am and he just called me at 9:47am, ELEVEN MINUTES LATER.  I explain to the guy that we were out of town and to please notify the police and he kept talking asking me do I want to call a neighbor and have the check it out first. ARE YOU SERIOUS??? Thank God this time is was a false alarm, but we will be looking for another security company because we are wasting our money.
(Added June 9/11) Met with sales rep, purchased system with a check which rep called in.  Installer showed up, home office had no record of payment.  He explained that it had been paid and installed the system. Two days later, I received a paper bill (addressed wrong!) for amount I had already paid.  Called customer service.  They had no record of original payment, and my 4 digit address was listed without the first digit.  No such address exists.  They told me to go to my bank and find out if my original check cleared and, if not, send them another check. 
I hope if I ever need them they'll be more competent in calling the law than they have been so far
(Added June 7/11) Terrible company.  Their employee Carol XXX robbed us of $630 2 weeks before Christmas 2010.  We paid for the installation in cash (which wasn't smart but it's ADT Security that'd never happen. Right?) We exhausted every remedy possible until we closed our account and went with Time Warner Security.  Now the company stands behind this thief through a BBB complaint, so we're off to small claims now. Scumbags! And the manager of this branch Mr. TXXXX refuses to return numerous calls and emails. Nightmare! And the service is ridiculously elementary to begin with!
(Added June 7/11)  Recently, we had a few suspicious events around our property, and I became concerned about my alarm system.  So I decided to test it out at around 11:00 PM on Saturday night.  I set off the alarm, and stood outside waiting for a phone call.  The alarm went off for 3 minutes before ADT called me.  I gave my passcode and demanded to speak to service, and told him that a 3 minute response time was completely unacceptable, and he apologized and said it was on them; but offered no explanation as to how it could have happened, and when I asked about having someone come out, he stated that there would be a fee.  He said they would have to charge because there were other calls that needed to be taken care of.
Can't honestly say I was a particularly polite from then on, but 3 minutes is more than enough time for rape/robbery/kidnapping.  3 minutes is not what I pay a monthly fee for.
(Added June 4/11) Had ADT for 5 years, with  a move and new installation 3 years ago.  When unit started to malfunction contacted ADT just short of the end of my contract and asked about repair.  Was quoted a show  up fee of $135, with $35 per 15 min of work time. Contacted my home warrenty service for repairs and found that the unit had been defective on its original installation, and the tech who installed it know it was defective (by way it was installed, bypassing defective zone connections and doubling up on other zones).  ADT wanted close to $500 to replace defective control unit -- even though it was defective at installation, past warrenty period.  Any company that will knowingly install a defective unit, and then charge full for repair when found out, doesn't deserve my business. Found a local company that will repair unit for $140, if home warrenty does not cover repair.  I have cancelled my service with ADT, they are a scam.
(Added June 4/11) We moved into a house that was originally a Brinks system, which switched to Broadview.  When an elderly occupant of the house needed a medical alert system, we got one through ADT.  Broadview had just become ADT.  (read the whole review...)
(Added June 4/11) I had been a Brinks/Broadview/ADT customer for 14 years as of this July. I was always very happy with Brinks and Broadview. They were a Corporate Family and very professional. They also never raised my rate in 13 years. When ADT took over I had concerns (read the whole review...)
(Added June 4/11) I'm not quite sure why so many people are complaining about ADT. It's not ADT. We had a guy named Brian Andrew from Protect Your Home come to our house and install the alarm. At first, I was very defensive because of all the negative comments on this site, but after he explained everything to me and walked me through the details of the alarm I was at ease and later apologized for being so defensive. He did an excellent job in checking for any issues, malfunctions or errors with the installation before he left. ADT is a great product for people that care to secure their home. Yes, it can be pricey for $129 per window sensor, but it's worth protecting your family and belongings. They offer a lifetime warranty on anything. If a battery dies, they come out and replace it for free. If a sensor stops working they come out and replace it for free. I'm not sure what these other reviewers are experiencing, but we are extremely happy with ADT and Brian from Protect Your Home in Santa Clarita.
(Added June 4/11) About two weeks ago, my husband and I signed up for ADT and were eager to experience the peace of mind that comes with having a home security system. Unfortunately we have yet to experience that peace of mind and have only dealt with hassle, incompetence and complete disappointment from this product and the employees who work for this company.
Every single day, the alarm starts beeping because of system/technician set-up failure (sensor too sensitive, sensor set up incorrectly, etc). Three separate technicians have come in three times to look at the problem and each time we are told the issue is fixed. Several hours after the technician leaves, the alarm start beeping again (typically around 1 a.m. waking us up, but that is the least of our problems at this point).
We cannot take it anymore. We were willing to honor the contract but we have never received any services! My husband cannot keep taking time off of work to have these technicians come by and not fix anything. Please note that we have not even had a chance to use the system; we keep it in the "disarm/sub-disarm" mode only so far because of the incessant system failure beeping.
Yesterday we were told by one CSR that yes, 3 times is too many and we can cancel the contract and have the system uninstalled. However, when the Escalation dept called back, he left a message saying they can offer us one free month. What a complete lack of integrity. Come on, do the right thing ADT. We are taking them to small claims court and will be sending our situation to Seven on Your Side. This company is the most unprofessional, straight-up CRIMINALS I have ever encountered. Do not ever use their services.
(Added June 4/11) BEWARE...ADT is resorting to unfair business practices in order to "keep" clients.  I am in the process of a divorce and like most divorce situations we are selling our home.  We had a motion detector added to the current system in our shed right before separation.
I now call ADT to cancel service due to sale of the home and they are telling us that when we "added" the motion detector to our system in the shed we "agreed" to a new THREE YEAR CONTRACT.
I know without a doubt the salesman never told us this when we added the motion detector as I would have never agreed to a THREE YEAR CONTRACT knowing there was a good possiblility that house was going for sale.  (Of course, I ask for copies of the paperwork to show we signed such an agreement and none can be produced).
BEWARE ADT IS TRYING EVERYTHING IN THEIR POWER NOW TO RETAIN CUSTOMERS BY DECEPTIVE PRACTICES INSTEAD OF THE OLD FASHIONED WAY....CUSTOMER SERVICE!!
(Added June 4/11) I got ADT installed for my mother three years ago. She had been telling me that she was unable to speak to a representative,because she was unable to remember her access word. She tried to get it reset on two different occasions, but they never got either fax. I faxed them the paper work for the new access code and realized that my mother had been without service for over two years, because she had the phone line removed a few months after getting ADT installed. When I asked if they could atleast install the cellular back up service free of charge since my mother had been paying her bill on time every month since the installation, they refused and said they would be willing to give her a 1 month credit. 1 month verses 36 months...need I say more? Not to mention that further investigation made us realize that they charged us for installation,but never replaced the Brinks Control Panel or the Brinks keypad. Upon contacting the BBB, they offered her a 3 month credit. I just want my mother to receive the proper equipment and service that she has been paying for the last 3 years.
(Added June 4/11) ADT has the worst customer service.  The sales representative came by to look at a new house I brought and signed me up for over $500 worth of equipment and two years monitoring, their minimum contract.  I was told that they would be there to install in about a week on a Thursday, between 8 and noon.  They called about 4 times to confirm the appointment, so I was sure it would go well.  I took the day off and at noon I started calling Justin.  By 5 pm I told them to cancel my service and return my money.  The technician called back and said that he would be there in 20 minutes and that I would get 2 months of monitoring free.  When the technician arrived he activated the existing system, but did not have the correct equipment to fill my order.  He told me he would call me on Friday to install the equipment.  He never called back.  I called Friday afternoon I called him and was told he got tied up and would be there first thing Saturday morning.   On Saturday, he finally showed up, but tried to install a smoke alarm in place of a carbon monoxide monitor.  When asked about this, he replied “it’s the same thing”.  Still haven’t got this situation worked out.  I hope their monitoring works better than their installation.
(Added June 4/11) ADT is a joke! I took over the system from the old owner when I moved into my house. Monitoring by ADT has never failed. Customer service - I can sum it up by saying I'm almost always shaking and on the verge of tears when I get off the phone with them. (read the whole review...)
(Added June 4/11) I actually read their contract, and line item 25 concerned me a great deal. To get into a 3-year contract with anybody with an early-termination penalty clause, I needed better terms than that.

Their notice of cancellation said I could cancel (read the whole review...)
(Added June 4/11) ****Do Not Use ADT At Any Cost****
My wife and I called ADT inquiring about their services.  After a long and impressive sales pitch, we scheduled an installation appointment for the following Friday, (read the whole review...)
(Added June 4/11) I have been a customer of ADT for the last two years.  I have had a hard time with them since the first install.  One of the sensors has been false alarming consistently, been replaced twice, and still having issues with it.  I have called ADT corporate to cancel the subscription, as I no longer activate the system due to worrying of false alarms, and ADT will not waive the early termination fee even though their system isn't working properly.  DO NOT sign up for a contract with them.  It isn't worth it and the contracts are three years with hefty cancellation fees.  Equipment isn't that great either.
(Added June 4/11) We used Brinks for years with no problems before the merger and now are stuck with ADT.  With absolutely no changes in our system, all of a sudden one of the doors would not arm.  It took them 3 or more visits to finally figure out how to fix it and there was (read the whole review...)
(Added June 4/11) ADT rebate center is the worst.  They will try their best not to pay you and decline the rebate even if you submit everything and it's correct.
(Added June 4/11) Regrettably, ADT has not met (my) customer expectation. ADT personnel appear not to have adequate knowledge of product lines.
(Added June 4/11) I received word yesterday that there would be an increase in my ADT alarm rate premium starting in May, 2011.  Could they pick a worse time during Americas' financial history to do an increase! They're taking food off my table, as that's where the extra money will have to come from to pay for this increase. Just like it does for what I have to pay for gas now. And don't even get me started on how they trap you into a 3-year contract term, which starts anew if you move. This company is a rip off, inconsiderate and greedy!
UPDATE: Recent ADT rate increase:  Be sure to read Paragraph 3 of your Residential Services Contract for either instructions for: 1. a waiver of the increase or, 2. if ADT chooses not to waive increase, instructions to be released from the Contract without having to pay the early termination fee.
(Added April 29/11) We've had adt alarm and two adt video surveillance camera's for about 5 years. The video camera, which was top of the line at the time is mediocre to poor picture quality at best. Forget night time video quality. It only captures daytime if a person is up close to the camera. We've had several techs out...(read the whole review)
(Added April 29/11) I installed and own my own DCS alarm system. ADT monitored this system for 14 years without incident. Last week I called ADT corporate ordering a wireless dialer so I could drop my landline.
The installer worked for 4 hours trying to get the dialer working with the alarm panel and despite hours on the phone, could not get it to work. At 4 PM Friday, the installer and his boss, XXX, agreed to reconnect my system to the landline.
After three more hours, they could not restore monitored service and offered and promised a new, "free" system Monday. I have never heard from them again. They are incompetent, and based on their behavior dishonest. Stay away from ADT and its shady dealers. I smell a small claims action.
(Added April 29/11) Very poor service. My system has not been monitored now for two months. I called the installer and they did not show up. After 3 calls, they still did not show up to fix the problem. Last attempt to contact them and their phone has been disconnected. When I contacted ADT they said they will find another contractor but refused to reinburse me for the two months of not being monitored. When I cancelled them, they charged me for 3 remaining months. Typical big business actions. Take my word for it. Do not use ADT
(Added April 29/11) We have had ADT as our home security system for 4 plus years. We have been nothing but happy with them. Our alarm works properly and well. After my son accidentally set off the alarm last year, ADT immediately contacted us and the police arrived at our door shortly there after. Customer Service has always been good as well as getting ahold of a representative. Our quarterly rate has gone up a few dollars twice in the past 4 years however, contrary to complaints I don't find it to be a negative. ADT monitors my family and keeps us safe, it is a small price to pay for good service!
(Added April 29/11) I am totally dissatisfied with ADT security systems. From the first moment they installed it to the present day. They will say you get a free system, then 3 guys will show up, "evaluate" your home and try to ...(read the whole review)
(Added April 29/11) I have no problem with our ADT sale guy.  He works for ADT and he was great.  Really the only way to go.  However, there service department is a joke, as frustrating as dealing with DirectTV, makes your blood boil, disrespectful.  They installed a glass break in our bedroom, however they installed it next to the door so every time we close the door normally it sets off the alarm.  I was told this is not covered under our warranty because it is not malfunctioning.  We would have to pay to have it relocated even though the install person picked the location.  It seems to me the ADT install person should be responsible for moving the device if they put it in the wrong location and it constantly sets off the alarm.  My problem was not resolved.  I guess ADT will use their resources calling me to make sure the alarm is false rather than moving it.  I refuse to pay for their mistake.  I am very frustrated and would not recommend this system.  Use one of the small companies that actually care about their customers.
(Added April 29/11) I purchased ADT secutity service on 2009, it was a huge mistake and I had horrible experence with ADT and don't want recommend anyone else to use ADT service.

(Added April 29/11) After receiving a telephone solicitation I decided to have the ADT representative come out. When he first walked in he asked to use the restroom - weird - very unprofessional. After sitting down at the table he talked incessantly (and loudly) through a well rehearsed sales script using a piece of paper. He kept citing the differences between the "Sales" department of ADT and the "Promotions" department (which he represented). An earlier review used the word confusing, and that was true in this case, too. I had to ask questions to determine what the "deal" actually was. His real life horror stories of what could happen were unhelpful, too. Suffice it to say, I will not purchase ADT services.
(Added April 29/11) I had to turn my case over to the better business bureau to mediate because I could not get a satisfactory response to the substandard installation by ADT. Eventually they responded and I got some satisfaction.
(Added April 29/11) I have been a customer of ADT since 1989.   I recently closed one office which was using their services.  ADT is now billing me for over one thousand dollars for cancelling their services.  I advised ADT that I would be cancelling as soon as I knew when the closing date was.  They are now billing me for the balance of the contract.  I asked about cancelling the contract on another building I own and they want seventeen hundred dollars for that cancellation.  My home contract has expired so I can cancell that at no additional expense.  I would not use this company for any reason.
(Added April 29/11) I have had my system installed for about a week now, and while asleep today, it was storming, and it set off the gsm system.  I was called immediately and awakened by the phone call. (I was upstairs and had the tv on too loudly and did not hear the alarm)  The woman that called was extremely nice and stayed with me as I checked everything to confirm that it was a false alarm.  I was very please with her patience and understanding of my fear during our time on the phone.  She stayed with me while I checked the entire house, closets and all, lol, and of course asked me for my security code word.  Over all I am very pleased with the response.  I believe I would like to check into getting a second alarm to sound upstairs so that I can hear it better, but that was not the fault of ADT.
(Added April 29/11) I've been an ADT customer since 1997 and have nothing but great things to say about their monitoring service...very prompt and always courteous.  Service, on the other hand, is obsurd!  Two years ago, my home took a direct lightening hit and caused extensive damage.  ADT's service tech was like a bull in a china shop and damaged window treatments, knocked a vase over and didn't EVEN pretend that he liked his job or wanted to be here.  He made no apologies for any of his damage, and, mind you, my home isn't cluttered and has sparse furnishings.  When he left he stated that the control panel needed to be replaced, set me up for 3 appts. and stood me up every time.  When I complained to customer service, I told them NOT to send the same tech back to my home.  They were kind and agreed.  Of course, who shows up?...the same guy--happy as ever to be here.  He then decided that I didn't need the new panel and all was well even though it sounded like a hoarse cricket, various zones alarm without reason, and takes 20 seconds to bypass a zone.  He said that it was normal.  Customer service was to send an "evening shift" tech out and he stood me up, too.  Finally, he called me and told me that these problems are "normal", also.  At that point I gave up and dealt with a limping system as I couldn't bear the indifference and negligence anymore.  Months later my entire system goes down and they offer to send the same guy out at an astronomical hourly rate.  Needless to say, I'm shopping around.
(Added April 29/11) I have had adt to replace 3 routers to my cameras. Each time they came it took a second trip to bring the equipment. I have had technician come out to take a look at the cameras with no ladder on the truck. So how was he to get up to the cameras. I complained to main office. He came back with a ladder but just looked at the camera and did nonthing.Of course the cameras went out then I had to get them back again. So the same technician came back that requested not to come returned with a more experienced adt person so the camera was fixed.The technician I did not want there keep telling the other adt person he checked this and that but I had to correct him because he did not do his job. I am not satisfied so I am buying my time. I also heard some other things about adt that makes me wonder about how loyal they are to the company.  I was also told by one service person it would cost $140.00 for the first 1/2hr to move a camera for a different view- That is way to much money to move a camera. So i can see why they are not #1 anymore.Like I said I am buying my time and keeping records of how many equipment failures I have had.
(Added April 29/11) My experience with ADT sucks, ADT is the worst, I wouldn’t recommend anyone to use it.
(Added April 29/11) Have had an alarm system for several years, originally installed by Brinks which then became Broadview, now ADT.   The alarm was in my parents home, they both died, I tried to cancel service and...(read the whole review)
(Added April 29/11) Worst customer service ever!  I've never talked to a meaner customer service agent.  We have been customers for a few years now, and I had an inquiry about my service and from the beginning, the lady was rude when I had to take a second to remember my phone number, she rudely stated to call back when I knew, when asked my address and I only gave the street address waiting for her to verify, instead of asking what city, she said, we are required you to tell us you whole address, so I said oh sorry, and gave the rest of the address, when I asked about my pin I said I could not remember it, she rudely said I needed that, and hung up on me.  I CANNOT believe I am with this company.  I talk to so many people on the phone and I don't remember anyone from an established company treating me this way on the phone.  So unprofessional.  Please fix your customer service ADT.  I'm appalled.
(Added April 29/11) Stay away from ADT. My alarm system was installed by Brinks and it worked fine, which has not been the case with ADT since I have Vonage, they claim that VONAGE will not work with ADT and I will have to pay $7.00 extra a month to become wireless besides signing a contract for 3 years.  
(Added April 29/11) Left to ADT, our house would have burned to the ground. We had ADT for close to 10 years and were marginally satisfied with their service -- repeatedly calling the police without calling us when they got an alarm, for instance. But last Fall (2009) we had a house fire and ...(read the whole review)
(Added April 29/11) I have an ex boyfriend that is able to enter my home without triggering my alarm system. I have small items such as clothing,towels,throw pillows etc. taken out of my home. I have also had small amounts of money taken. I have contacted adt and they just say everything is working fine and that it is impossible for this to happen. I pay $44.99 for nothing. I had just the simple $29.99 and they talked me into getting the cellguard well i still have the same problem. while i am pay $44.99 this guy is still coming in my home. might i add that this guy has also put dents in my walls, cigarette burns on my carpet and has damaged my countertops to the point i need new ones. i have had technicians come out and all they say is that everything is fine. i have witnesses to some of these events. i have called the police and they tell me to call my alarm company. adt tells me to call the police. however, i am stuck with this system that does not work and i cannot get out of their 3 year contract. can somebody please help me or give me some advice.
(Added April 29/11) Had a system installed I have pets, I was assured that a motion detector system was best for me and that the pets were not a problem since they are small, installer echoed the same line.the alarm was being tripped regularly, called out a tech. i was told that the cats were setting off the alarm, and was the wrong system for pet owners. tried calling no reply so I unplugged the system in 4 months I have not been contacted to see what is wrong, so much for customer support

(Added March 18/11) I had ADT for 3 years and my alarm kept going off for no reason.  Although they had my work and cell number, they would leave messages at my home (during the work day).  Since I did not answer, I always had the cops coming to my home.  I asked them to come and take a look at the system to figure out why it was always going off, but they refused saying the system was ok.  Then in September 2010 I called up to cancel my ADT and they told me I had a 3 year contract that did not expire till end of Feb.  If I cancelled then, I would have to pay a cancellation fee of over 250.00.  I told them I would pay till the end of Sept although I was not using the system and to cancel me in Feb.  They never told me I had to give 30 days notice. Customer service is horrible and can't seem to transfer without losing you and the cancellation department was very nasty as was the person I spoke to in headquarters.  ADT can take they crappy system and stick it where the sun don't shine. 
(Added March 18/11) Dissatisfied long term customer...I was an ADT customer for over 20 years and utilized a land line for monitoring, and had NO problems with the system. 10 Months ago we "upgraded" to cellular monitoring, but of course the basic system wouldn't handle that so we had to "upgrade" the whole system.  While they were at it we decided to replace the smoke detector because of its age.  6 weeks after the upgrade the smoke detector went off for no reason.  My husband was on the phone with ADT and the fire dept pulled up, even after my husband told the monitoring staff that it appeared to be a false alarm.  This happened twice.  ADT decided that the alarm was faulty and needed to be replaced.  Out of the goodness of their hearts they replaced it for free. When the tech came out he told us that 'new doesn't mean better'.  We have had at least 1 call a month about the system throwing 'codes' or other issues since the "upgrade" and ADT feels that its not their problem that their equipment is faulty.  I've called and talked to at least 4 people and all I get is I'm financially responsible even if the equipment is at fault.  To fix it completely I might have to replace the whole system at my cost - after I already paid to have it installed - and when I assumed that I was installing working reliable equipment.  If it was my fault, I would not quibble about paying to have it fixed but this system has been a problem since day 1.

(Added Feb 14/11) My office got broken into this morning.  Front entrance was shattered but the alarm did not go off.  I have motion detector 3 feet away from the door.  Called ADT this morning and reported the problem.  I was told my alarm is working fine and maybe something wrong with my phone line.  I was instructed to call my property insurance to file claim...   Called again, second agent kind enough to test the monitor with me.  She indicated the motion detector did not work properly and recommended a tech to come out.  The kicker is, it is going to be about $260...  Can you believe it?  Called again and asked to speak to someone higher up, broken record.  They only guarantee monitoring not labor, so I still need to pay for labor.  Gave phone to my husband, after talking about 5 min, (they) will waive the fee.  Consumers be aware.  I have ADT at home and I am seriously considering switching.  The way I am being treated by ADT make me more mad that the actual break in...

(Added Feb 4/11) I became a customer of ADT monitoring on Dec. 28, 2010.  On Jan. 16, 2011 an ADT rep contacted me to let me know that there was an alarm going off at my home. I notified her that I was at work and to dispatch the police immediately.  I left work and headed to the house.  20 min later, as I am turning into my subdivision, the rep calls back to tell me that she could not find the correct agency to dispatch, so I just needed to contact the police myself. By this time, of course, the robbers had made out with my stuff and i was left to foot the bill to replace things.  I called ADT, since no one from ADT felt the need to contact me to address the situation, and I have received little to no feedback.  the one thing that they did admit was that they could not dispatch the proper agency due to an error on their part.  However, even after contacting corporate, there has been no action on my situation.  My calls have been left unreturned and I even submitted a letter with police report to corporate.  I still have not gotten a response!!!!  I am attempting to opt out of my contract but they are even giving me the run around about doing that even though they clearly failed me. ADT sucks!!!! Please look into other companies before choosing ADT!!
(Added Jan 26/11) We have been having a lot of issues with our ADT alarm system. It's not new, but not old either- just a couple of years old. In previous years, we've had the alarm go off without cause. I will admit, the one thing I really like about ADT is that they are very good about calling when the alarm is tripped. BUT, because most of the time when our alarm is tripped, its a mistake on the machines part, you would think they would come out and fix it, right? That's exactly what didn't happen. There hours for repair are ridiculous for working people. I believe its like 8am-5pm. You'd have to take a day off from work in order to have the technician come out. So, I put it off. Until last night. The alarm would not shut off. At all. For 40 minutes (40!) the alarm beeped and screamed and shrilled. And the best part- they didn't know how to make it stop. I talked to 10 different people before I finally had to take a hammer to the machine to get it to stop (I know- but it was 3am- again, I had to work.) That was last night, so I don't know how this is going to progress. All I know is that I want a new provider, which is why I'm on this website.
(Added Jan 25/11) Two installers came to put in our system. I had many questions but they were in a hurry to get to their next job so most of them didn't get answered. One man was training the other; the trainee was working very hard and fast but knew next to nothing. The other was outside smoking most of the time on his cell phone. Since Mom is in her eighties and both of us have cognition problems, I needed someone to explain clearly how everything worked. That didn't happen so consequently we used it maybe three weeks? Both of us tripped the alarm maybe five times, terrifying all our animals and nearly causing heart attacks in both of us and now? We pay $35.78 per month to ADT for an alarm system we don't use. I wrote a letter explaining the situation but they said unless Mom was dead or in a nursing facility basically oh well. (There was much more hassle involved than this ~ they forgot to give us a form we had to first get, then take to the police, probably the worst customer service ever on the phone and messed up billing. I'd advise folks to get a can of bear spray rather than pay these jokers.)
(Added Jan 15/11) Our experience with ADT has been great, no problems to report. Questions that we have are always answered in an efficient and friendly response.

(Added Jan 12/11) 15 year customer with the maintenance fee. My dog ate my portable control pad. Called to have control pad removed from system (NOT replaced). ADT wanted $137 for the first HALF-HOUR of service to remove the keypad. $137? Really? I don't think so. Good bye ADT.  But wait, there's more!  They tell me I have to give them 30 days notice to cancel. After 15 years of service I owe them?

(Added Jan 3/11) I'm a new ADT customer and I received a fast, confusing consultation when they visited my residence.  (I had already decided to choose ADT because of the special discounts I had available to me.)  Later, when my first payments were deducted from my bank account, it was a much higher deduction than I was led to believe.  I thought I would pay for one month up front and for each month thereafter, but no, a double payment has to be paid on day one.  I called customer service and their rep gave me a snotty, "better than you" attitude over the phone.  She explained my payments in a confusing manner, and I had to repeat what she said but in a more accurate, correct description.  Poor, poor attitudes of some young ones these days....and ADT employs them.

(Added Jan 3/11) We have had ADT for 3 years. Don't like the price increase w/out warning (it's up to $56.47/mo) in Ohio and the charges for someone to just come out and look at a problem. Otherwise, it's been a nice company with kind people.
(Added Jan 2/11) This review concerns the monitoring service (corporate) for ADT.  I cannot overemphasize how completely useless and worthless this service is.  Do not waste your money.  During the recent holidays, I received a voice message (left at 2:00 p.m.) from the monitoring service that my mother's system indicated an alarm activation.  Unfortunately, I did not return home until three hours after the message was left.  But, during that three hour period, ADT took no action to contact the police.  I found this out because at 10:30 p.m., the ADT monitoring service called again indicating that there was an alarm activation at my mother's house.  It was now a total of over eight hours since the alarm activation was first initiated and the police had not been contacted. This was patently ridiculous and I hung up the phone.  At 1:00 a.m., my mother called me and stated that ADT had reached her and that they had informed her that her alarm was activated and yet, they had still not contacted the authorities.  I discussed the timeline with her in order to explain that if there was a burglary, I was pretty sure everyone had cleared out since this was now 12 hours in the making.  However, the police should review to ensure safety.  This is not the only occurrence we have experienced regarding their lackluster service but just the most recent. I sincerely regret referring ADT to my mother and relatives. I will cancel their monitoring service and my mother will also.
(Added Dec 30/10) I chose ADT because of their 24 hour monitoring service and low installation price. However, I am unhappy about a few things. I called once and said I wanted to disconnect my land line phone and if this would cause any problems. The CSR said no, because I had a wireless alarm system. I asked her to make sure. She said no problem if I disconnected my land line phone. Three months later my security alarm has some strange beeping. I called ADT and the CSR said that I had no phone line hooked up so my system had not been working for the last three months. Wow. I told her what happened and of course there was no record in their system that I had called three months earlier and was told I did not need a land line phone. I asked for a refund for those three months that ADT had not been monitoring my house and was denied. They said it was my fault for not having enough sense to realize that I needed a phone in order to be monitored. Then I tried to create an account on their website so I could view my bill.  It took me an hour to try to do it. Their site was so user unfriendly it is unbelievable.  I kept entering my PIN, my password, my phone number, and it was saying that my information was not in the system. Great. The last time I entered all the same info, miraculously, it created a user name for me. I will not use this company again. When my contract runs out next year, I'm done.

(Added Dec 23/10) Have had ADT for 18 years. Used to be Westec. Service is terrible. They have only one serviceman in our area and we have to wait 5 -7 days for an appointment which means we have NO SECURITY during that time. how is that keeping you secure??? Was told call would be between 8 a.m and 12 pm. Came at 1:30 pm only to tell me system too old and cannot be fixed. How is that keeping me secure? I urge you to not use a National Company for your security. Go local.
(Added Dec 12/10) I've been stuck with adt for 6 months now they locked me into a 3 year contract on a business I own even though they didnt put any new equipment in, just transfered over to my name. Half the equipment looks like it was put in, in the 70s. Service has broke down 5 times I get charged for them fixing and pay monthly fee even though its old junky equipment. My alarm is off for days on end while waiting for appointment for the same thing they fixed last week.  Seems like their should be a limit on how much you have to take before you are allowed to cancel service without having to pay 2 1/2 year cancellation fee.  Sales rep. who was so nice signing me up gives me the "oh well" when I finally hunted him down.  Kicking myself for letting them push me into long contract.

(Added Nov 24/10) Now that Broadview has merged with ADT, the situation is still worse. If the alarm does not work (for example CP error) ADT states that this can either be a fault of the network provider (AT&T or Comcast) or it can be ADT.. but ADT will not be able to diagnose it remotely. Even if the phone is working fine, it can still be a network problem ... ADT customer service personnel stated that it might be an increase in voltage for better connectivity..!!!!! Either way we end up paying 75$ per hour for the ADT technician if their software suggest that its a network issue and not ADT .. who is to validate this claim...why can't ADT validate this remotely. They never bother to check if the alarm is working or not.
(Added Nov 16/10) Have been a loyal customer for 15 years. Called to inquire to the fee to switch to cellular monitoring since I'm cancelling my POTS. Agent stated a price close to $300....not! I've also researched DIY systems that are cellular.  I mentioned this to the rep and asked if this was the best ADT could do and got no response.  I guess along my POTS I'll be kicking ADT to the curb.  The definitely do not have any customer retention goals, too bad!
(Added Oct 30/10) Alarm is excellent.  The sales rep not so after he makes the sale.  Still waiting for my CAA dollars 3 months later.  Alarm is excellent & installer was very good.
(Added Oct 29/10) I just came home and apparently my alarm had malfunctioned during the day and no one called me.  There were all these errors on the screen, so basically my house was unprotected and no one at ADT felt the need to contact me.  When I called to find out what my contract expiration date was, which thank goodness has now expired, so that I could change to a reliable company they didn't seem to care that my alarm had malfunctioned.  When I told them that I was going to disconnect service once I got a new alarm company because I was very dissatisfied with their service, the ADT operator asked "ok, was the date all you needed tonight?".  This obviously shows that ADT couldn't care less about anyone and, trust me when I say, that I'll make sure everyone I am in contact with finds out what a horrible, customer serviceless company ADT has been.
(Added Oct 29/10) ADT is a useless security monitoring company. ADT supposed to contact your 1st phone#, if no answer then they should call the police. Nope. When our house was burglarized on Sunday night. ADT spent about 15 minutes trying to contact me & my wife's cell phone, they even called my office# (on Sunday night!!). Finally they confirmed that we were not home THEN ONLY they called the cops!!! We had lost an estimated $15000 on that short 10-15 minutes of ADT screw up. Please stay away from this piece of crap company.
(Added Oct 20/10) (ADT Employee) I am currently one of the top 10 salesman in the nation.  This is due to the reputation of ADT.  Most all of my customers are trusting ADT to provide the best monitoring in the nation. With over 130 years of experience they are number one.  Many new products will be avalable very soon and I am excited to provide these new and innovative sytems to our customers.
(Added Oct 14/10) I have used ADT alarms for the last 6+ years in two different states....(read the whole review)
(Added Oct 5/10) I signed a three year contract on 4/27/2010, for home security.  I was told for the security system to be installed into my house I need to pay $504, which I wrote them a check for, but would get $250 back as a mail in rebate.  I asked my sales rep if I needed to fill out the paperwork and send it in.  He told me no that he would take care of it and I would get my rebate in about 6-8 weeks.  About the end of July when I had not received anything I started calling about it.  My sales rep at first would tell me he was looking into it, eventually stopped taking my calls. After many phone calls and many messages I finally filed a complaint with the better business bureau.  After I filed the complaint I was contacted by customer relations and was told my rebate would be to me within 4 weeks.  Towards the end of Sept.  I got a check for $150.  Again I have tried calling several times and have left several messages trying to find out why I only got $150 and not the $250 I was promised and no one will call me back.
(Added Oct 5/10) Had Brinks/Broadview for 2 years - was happy.  ADT took over.  Last week I received a "communications" error.  I called the 1-800 number.  I was told that Vonage had changed its program and Vonage and ADT were no longer compatible.  I asked "Well, what do I do now?" I was told that I could purchase 2 types of adapters for $170 to $190 respectively and have $5.00 to $7.00 added to my $40 a month ADT bill.  Or, I could get a different phone provider that was compatible with ADT.  None of those options appealed to me as I made sure before I signed up with Broadview/Brinks that my Vonage phone would be compatible.  I asked to cancel my account and was told that I had 12 months left and if I did not pay I would be turned over to a collection agency for breach of contract!  What? I did not breach the contract.  ADT did when they could no longer communicate with their equipment!  Rip off!

(Added Sept 26/10) ADT has deceived me and is using borderline fraudulent tactics....(read the whole review)
(Added Sept 26/10) I have a 3 year contract with Broadview. I have been a Broadview customer for a year and I was happy with their service until they were acquired by ADT recently. ADT never supported VOIP phone, but Broadview did and that's why I went with Broadview to begin with. Now that ADT has taken over, they are pushing signals through the system that causes my system to beep at the monitor. I called them to have it resolved at their expense since I didn't have the issue with Broadview, but they are asking me to pay $90/ hr to fix it or pay a monthly fee to get their protection plan. I think ADT should respect the contract we have with Broadview and either pay for the changes they are making to my system to make it compatible with theirs or let us out of our contracts. I find it offensive if they force us to pay for the changes they need to merge their systems. it is only fair they pick up the tab ! I wouldn't want to continue with ADT if they put their bottom line ahead of customer needs.
(Added Sept 25/10) (Updated Jan 3/11) I am so disgusted with ADT right now, if I would have been notified that they merged with Brinks/Broadview I would have found a new company earlier.  This morning our alarm starts beeping at 5 am saying that we have a communication problem.  They will send someone out on Thursday, excuse me no I want this fixed now.  So now they tell us switching phone providers has caused this problem, we switched 6 months ago and we are just getting notified now that it is not working, so apparently it has not been communicating with them for 6 months and I have been paying.  I asked that they tell me when the last time I activated my system?  They could not tell me that, only the last time it went off.  Okay so if you are monitoring my home, why would you not call and tell me that the system is not communicating.  Been a customer for 13 years and I now do not feel safe in my home because they are not monitoring it the way it needs to be monitored.  Thank god I put my own camera systems in and not their camera system.  I just wasted $240 on something that was not working, and now they want to bill me $90 to come out and fix this.  Company is a bunch of crap.  They are out to make money not help you feel safe.
Update:
No the issue was never resolved, we switched alarm companies.  I would never tell anyone to go with ADT ever.  They billed us every month for a service they were not providing and then on top of it billed us to have a guy come out and fix it.  They got 6 months worth of payments that they never gave us the service we paid for.  Never again would I ever go back to this company.  Our new company has been wonderful, if they thought there was a problem they called us and came out to fix it on the same day.  ADT would have never done that.
(Added Aug 25/10) (Updated Jan 3/11) The salesman was a total fraud.  At least 5 things he "promised" during the sales call turned out to be lies.  Some of these issues were key to the functioning of the alarm and the effectivness of ultimate purpose, securing the house and more importantly, my family.  The costs were mistated, the system didnt work as promised and we still have not used the alarm since the motion detectors will set off the system because of the dogs (which salesman said was not a worry). All "post signing the contract" phone calls to the salesman to fix or clarify things were not returned, in fact, not one phone call even though several messages were left that said this is very important, please call back,,,, nothing.  Dont use ADT ! (and beware, unfortunantly, Broadview might not be that much different since ADT took them over).
Update:
After calling the companies main office and insisting on talking to the general manager, I did get some help.  They cant make up for all of the problems the salesman created, but they did do a few things to make us a little more satisfied.  We are now using the alarm and have not had any problems.  I would change their grade from F to a C.
(Added Aug 25/10) We had an ADT alarm system installed in June. Installation was done well and the alarm service is fine, but the billing is terrible. They can't get it right. They make the mistake and the start calling for payment three times in two days and this is after they were paid. They were suppose to that the payment automaticly from a credit card. I just got another bill that states I'm late. I'm just about ready to cancel their service.

(Added July 26/10) My Husband & I signed with ADT in September of 2001 to have our home alarm system equipment installed & agreed to a 3 year monitoring contract, 5 years later we turned off our alarm service with ADT. In 2008 due to an increase in crime in our area I called ADT to begin monitoring again, we already had our ADT equipment in our home. The representive came to the house & the papers were signed- so again I was locked into a 3 year contract just because I wanted to restart servies- NO SYSTEM HAD TO BE INSTALLED AT THAT TIME. 2009 we sold our home & begin building a new home- I did not have ADT service at my home for 1 year & a half-due to building, but had to contine paying ADT when they were not even providing service because they were going to charge me with an very high cancelation fee. They CLAIM you can transfer you contract anywhere in the US- but beware because when you transfer- keep in mind they will not let you out of the existing contract, SO THEY CLAIM, & if you try to tranfer they expect you to sign another 3 year contract, just because you moved. They WILL NOT let you transfer only what's left of your exsisting contract. Also they will raise your monthly rate to whatever they desire. The monthly rate agreed upon in the contract NEVER stays the same- they increase it 2-3 times a year. I just want to pass this on to anyone needing an alarm system.
(Added July 11/10) (Updated July 12/10) We signed up for an ADT security system due to increased incidents of crime in our Bethesda, Maryland neighborhood.  At the time of signing, however, our house was being remodeled, and contractors/laborers were entering and leaving daily.  We made only one stipulation to the salesperson: that there would be no monthly  monitoring fees until we decided to actually activate the system, at which time we would notify ADT that we had activated.  The salesperson agreed.  However, we have since been receiving bills for monitoring service that we have not utilized.  To date we have been unable to contact the salesperson about this matter, and we have not paid their bills.  Our dilemma continues. 
Update:
Recent development: late Friday, July 9th, my wife said the salesperson gave us a $90.00 credit representing  three months' charges.  We are satisfied with that response, and hopefully things will revert to normal for the balance of the contract period.
(Added July 11/10) Do not waste your money and security on ADT.  You spend more than a $1,000 getting set up,  then you pay a monthly fee of $29.95.  Within six months the sensors begin to fail and you get nuisance alarms.  When you complain, ADT tells you it's the batteries.  You replace the batteries at $6 each with no effect and ADT tells you it's still the batteries . . . They offer to come out and check your sensor and fix them for about $185 each.  Then you start turning off "zones" to stop the nuisance alarms. Finally when you've had enough and cancel, they skin you for another month's fee -- the 30-day notice provision. In brief, ADT's technology is shoddy and their business practices are abusive.
(Added July 10/10) I've had ADT for about 4 years. Never had any issues . . . even with Comcast Digital Voice. And yes, it's been tested! My issue was that they kept raising the price which was NOT justified. Costs aren't going up and I'm not getting any better equipment.  In case anyone is curious, your contract probably does allow termination on price increases (mine did)-- although they did offer to waive the price increases once I told them I had signed up with someone else because I had had enough of their increases!!

(Added June 24/10) ADT bought up my contract from Counterforce Security with whom I had been very happy. I "tested" ADT's response time today by setting off the alarm twice.  They never called.  I called them and was told because I had myself inactivated the alarm they did not call.  Well, I might have inactivated the alarm at gunpoint!  (Note from Admin: If you're worried about having to enter your code by force, you can have your alarm company program a "duress code" that disarms your system, but also sends a silent panic signal to your central station) I didn't like their attitude and response on the phone (lots of waiting time from person to person) and undoubtedly will find a better replacement by my renewal date.

(Added June 2/10) ADT's installation billing is a scam. I had a previous alarm and ADT took over the monitoring and used much of the equipment. They charged me for an outside sounder, but never installed on because my old one worked fine. Technician said it wouldn't be a problem - just call for a refund on that pieco of equipment. Not a problem - what a joke! $ seperate calls over two months providing every detail of information, the only responses ADT gives are that they are "looking into it" and that a credit had been submitted, but it takes a month to "process" - what rubbish! They could simply credit my credit card that day. To all who are shopping ADT versus Broadview - If I had to do it again I would go with Broadview (or anybody else!) This is the type of lousy service you can expect from ADT!
(Added May 28/10) (Updated Sept 16/10) ADT has been double billing me for three years. When I moved from my previous address to my current address, I contacted ADT via their web site and arranged for alarm service to be stopped at my previous address and for a new system to be installed at my new residence. I put the automatic monthly charge on a different credit card. ADT installed a system in my new residence, but never stopped billing me for my cancelled service. I discovered the double billing in March 2010 and contacted ADT corporate customer service about it. I've contacted them three times since. Each time the response is "Give it a little more time". I get the impression the customer service representatives are reading from a script. ADT owes me $1,534. It's been almost two months. If my wait reaches two months, ADT has lost a customer.
Update:
After a considerable wait and some communications difficuties, ADT investigated my claim, found it to be valid, and refunded all the money due to me. ADT Customer Service representatives were very helpful and courteous throughout the process. They even called to confirm that I had received the refund. I intend to remain an ADT customer for the forseeable future.
(Added May 27/10) I recently relocated my business.  We had ADT at the old office for 7 years.  They bill in advance for service (pay today for the next 3 months).  We paid a pro-rated share of the bill based on our move-out date.  That didn't stop ADT from harassing me daily on my cell phone for payment (that we didn't owe) during the hectic process of packing, moving and unpacking.  We left the alarm off when we moved out.  This morning, I got a call at 7:22 a.m. on my cell phone from an ADT person wanting to conduct an unscheduled inspection of my old office.  When I called ADT to complain about the harassment, the representative offered absolutely no apology and told me it's just like if you don't pay your cell phone bill you get daily calls.  Big difference though because ADT harasses you for payment for FUTURE service.
(Added May 18/10) I used ADT for my home monitoring until today when they called and reported a "failed communications test".  This is the fifth month in a row with such an "event".  ADT refused to pay for the service charge to come out and look at the keypad they modified exactly five months ago.  Until ADT "upgraded" the keypad I never had a problem with failed communications tests.  Their response to me was that I should have initiated a service call sooner.  Please remember that ADT was already aware of the problem as they called to report the problem to me every month.  I don't mind a mistake in the installation of their product, but to tell me that I was responsible for the fee to correct a problem ADT already knew existed?  No thanks...terrible customer service!!
(Added May 18/10) I called ADT for a quote for an alarm and surveillance system for my business. They had one of the lowest quotes, and I decided to go with them because they are well known.  The sales person never showed for the scheduled system installation. nobody called, and it was very hard for me to get in touch with him. He did not answer his phone nor his email.I found out later, the salesperson took a week of a well deserve vaction and left me hanging. I finally got the system installed, it's been 5 months still don't know how to operate my cameras, I made a few phones call and answered surveys and still haven't gotten any help.  If you're reading this I would suggest you find a company with a good customer service. ADT sucks, they care until they make the sale and then you are on your own.
(Added May 7/10) My house was broken into in July of 2009, and stuff was stolen.  I decided to get an alarm and chose ADT.  The installer came in, installed, tested and left, everything seemed fine.  A few times I accidently set off the alarm, and ADT never called or sent police.  My dad's alarm company does every time, when he accidentely sets his off.  I called ADT, they advised I shut the alarm off too fast for it to go through the lines to them.  Months later, my wife asked me to test the alarm so I did.  It did not work.  ADT sent out a technician.  The technician could not figure out why it did not work.  ADT blamed it on Comcast Digital Voice, and said they are not compatible.  Their website sure says that they are and so does the Comcast website.  I had a Comcast technician come out and see if the problem was on their end.  He said everything was hooked up right for Comcast and ADT.  ADT has been charging me for 4 months now, for an alarm that still does not work.  I asked them for a fix or I will change alarm companies.  They told me they would call me back in a few days.  I am pretty ticked.

(Added Apr 6/10) I had ADT for years, but dropped their service.  When I first got the alarm system about 10 years ago, as soon as the alarm sounded (twice in 10 years), ADT would telephone me immediately to see if I was o.k.   When the alarm went off not very long ago, it took over 5 minutes for ADT to telephone me.  After waiting and not hearing from them, I myself telephoned 911.  After a few minutes more, ADT finally telephoned.   I could have been dead by the time they called.   I also understand that if ADT cannot contact you, they telephone the second number on the list, asking them to check, and then they call the police.   By that time, my house would have been cleaned out, or I could have been attacked.  When my contact expired, I did not renew.  They used to be such a good company.

(Added Mar 4/10) This morning at 4:15 am my alarm went off, it woke me up I then woke my husband up, he thought it was the telephone so he hunted for which phone was ringing I told him it was the house alarm, then he reached for the gun, we got up he went into the front room and checked then went into the garage and checked. Ath the point in which he had made sure all was well I turned the alarm off. This took at least 2 minutes. ADT NEVER called to check on us.  We got back into bed and had just settled down when it went off again. We went thru the same steps and I let the alarm go to see how long it would take ADT to call and see if we was still alive. No call.  We stayed up this time and the alarm went off a third time. Still no call from the people we pay to watch over us so I called them. The lady said well the alarm was disarmed do you want us to call in cases like this, I said yes, unless you want us to find someone else.  How did these people know someone wasnt holding a gun to our heads telling us to shut alarm off if we didnt want our heads blown off?  I am on the internet at this time hunting someone else, One thing I know for sure is they can't be any worse than ADT.
(Note from admin: "Cancellation Signals" are common in the alarm industry.  You can also have your alarm company program a "Duress Code" in the event you are being forced to disarm your system).
