"Within minutes, every carbon monoxide detector on every floor of the house was going off and ADT called me immediately. Thank goodness ADT called me after three of my alarms kept warning me to evacuate and insisted that I do so."
Lynn McNelly, Colorado
"I heard a loud noise at the back of my house. Glass was shattering from the sliding door on the patio. ADT called me right away and I told them to send help because someone was in my house. It is reassuring to know that ADT and the police officers were there."
Wendy Haughian, Washington
"One of the firemen the night of the fire said, 'Do you know how lucky you were tonight?'. But I like to look at it as, we weren't lucky we were protected (by ADT)."

You have given me my life back!!! I am a senior citizen with a beautiful home in a once wonderful neighborhood. With the passing of older persons: my family as well, these once well-kept homes became rentals and with that came the lack of interest in maintaining a property, and a lack of respect and behavior regarding those that dwell in a living environment. My situation was not unique. Drugs were just about everywhere. The children of one of the landlords was involved in buying and selling. The people that came to the property were loud, and their language disgusting. Their treatment to me and my property were the trappings of a sick and drug-affected mind. Even to the point of telling an unrelated party that they would poison my dog.
With ADT: the cameras and system, I am free to work in my yard without fear. My dog is safe. My garden unpolluted with trash. The selling of drugs in the driveway stopped. In fact they moved their family to another location because the father felt spied upon. He did that with a threat to make war on me: if I did not remove the cameras!!! After calling me every unsavory name and swearing he (the father) finally left with his sons. I was safe in my home. I am almost 70. I am still very active! Thank you!!! I now have a family to care for me!!! That is ADT. Your representatives are young enough to be my grandsons. They are respectful, and very kind to me. I don't know what I would have done without you!!! God Bless you for your kindness and professional abilities.
Gus, we are looking forward to many years of serving you and monitoring your home. We are so glad you are part of the ADT family! Thank you so much for sharing! Have a great day, Gus! -Katie

I have had ADT for 6 years and I am 100% totally happy with their process of home security. When I sometimes press the wrong button, or if batteries in window detectors go dead, or if noises occur and set off an alarm, ADT is immediately on the phone to determine the cause of a security signal. I am so proud to be their customer. I recommend ADT to everyone looking for home best security. ADT is absolutely the best home security company in the whole world. I love ADT.

I've had ADT for a few years now and will not have any other Security Provider. The best I've ever had; and I've had others before. When I've had an issue, I've always got a detailed and quick response. The Technicians have always been very professional and sensitive my needs. Yea for you guys!

I have always trusted ADT to protect my home and family. They are conscientious and courteous. I have recommended them to my family, friends and neighbors. They offer you the basic protection plan as well as the Medic-alert console. With this option they provide a feature in which they test your system monthly so that they could hear you in case of a medical emergency. I had to use them on one occasion in which they had to contact emergency services to get me an ambulance to get to the hospital. They literally saved my life.

My husband's key FOB broke on its own and ADT was very prompt about sending a technician out to our home to replace it. My husband said the technician was very pleasant, prompt, professional and explained to my husband in detail and new features to the new FOB. We have had nothing but excellent service from ADT, not to mention peace of mind for our safety while in or away from our home. I would and have recommended ADT to family and friends, as we at the utmost confidence they have our best interest in mind.

Over the past several months, I have had the necessity to call and speak to the Customer Service representatives. Each time, they have been courteous and knowledgeable and treated me with the utmost respect. No fear or hesitation when I need to call them... nothing like having to call other companies' CS offices! Keep up the magnificent work!

ADT is one of the best Security Systems companies on the market. They always notify me via phone calls (home and cell) as well as e-mail whenever they believe there is an unauthorized entry on the premise. If you didn't authorized anyone to enter the premise and the alarm went off, ADT would immediately notify the police on your behalf. In addition, they're extremely reliable whenever services are required.

Honestly, I've set my alarm off numerous times from my baby hitting the panic button to me leaving a door slightly open to trying to change the battery in the wrong fire alarm unit by popping it open and every single time I get a call from the nicest most respectful people on the planet making sure I'm ok. It's a comfort to know someone is there every single time without delay. And guess what if I miss the call and don't call them back they contact the police. Yes that happened too.

I love the peace of mind having ADT has given me. I have pets and my biggest concern is their safety when I am not home. The couple of times that my alarm has gone off (once for a glass break alarm when I was home, once when I opened the front door without disabling the alarm) ADT was on it! They called right away! The company that installed my system, Safe Haven here in St. Louis, was awesome as well. The person that installed was professional and thorough. I was impressed! This is important as it is the first face of ADT with the customer. Well done ADT!! I will highly recommend you!

We have had ADT for almost 20 years in our home. We highly recommend ADT to anyone looking for a company to monitor their home. Whether we are home or away, ADT protects our home and belongings!

I feel comfortable going on vacation for eight weeks knowing that ADT is babysitting my home. I feel great knowing when I am asleep that ADT is watching over me.

I have had a great feeling of being safe with ADT. I have had a few issues (my own experiences with setting of my ADT alarms) and the ADT representatives were so helpful and understanding. They were very helpful and polite too and walk me through my problems. What great team. They are very understanding. Also the person that installed our new system in our new home went above and beyond installing the system. What a great experience with him. He is the BEST!!!

I feel safe and comfortable knowing ADT is on my side. I love how they send text, email, and calls you if alarm goes off. You know in seconds if an alarm goes off. Also they have cameras which is fantastic. I highly recommend ADT to anyone. Very professional.
I talked with an ADT operator over the phone and was quoted a price for the pulse security system for my home. I was happy with the price and set an installation appointment the following week. Once the installer arrived, he walked through my home and quoted me much more than I was told originally. I talked with the owner of the authorized dealer and she said she would pull the phone recordings to hold up their end if I was promised what I said I was. A week later I called her again and was spoken to in a way no customer should ever be treated and hung up on. She said ADT liaison had the phone recordings and she could not help me, I needed to speak with ADT, and to never call them again. That sent me on a game of phone tag trying to find someone from ADT corporate to listen and was told they cannot help me because it was an authorized dealer.
I don't know why ADT would want to associate with an authorized dealer that treats their customers this way. I am now without a security system. A stranger walked through my home and knows every entrance and the layout to my home. I was talked to in a way no one should ever be talked to, and wasted hours of my time trying to get to the bottom of this and got nowhere. I just want to hold ADT and their authorized dealer, Night Watch Protection Inc, accountable for their actions and potentially save other customers from the hassle I have been put through by advising them to avoid ADT all together. I'm not saying ADT could never do any good, but is this really the type of company/customer service you want to associate with?

Reliable, accurate, 24k gold security. This is the Ferrari of home security. The camera monitor and security sensors are always on. The technical team will help you every step of the way. ADT gives me complete peace of mind at home and when I'm away. If it matters then protect it with ADT.

I have had very good customer service from ADT for over 12 years now. I recently moved, and there was no question that I would renew with ADT for my new home. Each time I have needed to talk to a customer service representative or have someone come out to the house for an issue, I have received nothing but outstanding service.

I called in because our battery is running low and I was unable to locate keys to our box. When I spoke to the customer service rep she advised me that the keys are probably on top of the box, which they were! She then told me where I could find a replacement battery and how to replace the battery. The customer service rep was great help and I was on and off the phone in the matter of a few minutes, I did not have to hold for long at all.

I am having two wood doors, with sensors, replaced with steel doors, and I needed to know WHAT the procedure would be to have this "change" take place, and I received it from "Kynesha" (spelling?) in the form of EXCELLENT customer service. She answered my questions, and she educated me on the process, and she provided great advice. Thank you.
