While you can learn a lot by reading the ADT reviews on this site, you won’t have as much luck on the official ADT website. The security company is not very transparent about the pricing of the plans or equipment. For example, you are unable to see at a glance the price of motion detectors, additional control panels or carbon monoxide detectors. Potential customers should also be wary of what prices are shown. There are often additional fees that will raise the total bill when all is said and done.
ADT is the largest security service provider in the U.S. and Canada, and it has been protecting its customers for over 140 years. ADT alarm systems are expertly installed by technicians who can sometimes visit your home the next day. ADT is perfect for customers who are okay with paying a bit more for their state-of-the-art equipment and technical support and maintenance. The equipment available varies by area and dealer, but customers can choose from Honeywell, General Electric, and ITI manufactured systems. 

Hello Paul. We are sorry for your experience with one of our authorized dealers. Millennium Alarm Systems INC is an independently owned and operated retailer of our monitoring services. Therefore, they install / sell their own alarm equipment and are not owned by ADT. If you have any unresolved concerns with Millennium, we can reach out to them on your behalf to assist further. Thank you. -Andrew
With ADT Pulse you can control things like lights, door locks, garage doors, and your thermostat all from your smartphone—though it is one of ADT’s more expensive monthly plans ($52.99 per month). ADT is also one of the highest-rated companies for security performance because it uses technology and equipment from Honeywell (the same company that manufactures many high-end commercial security products).
I have experienced ADT security at several different places I have lived. The customer service reps are very professional and helpful. We experienced one bad experience where the alarm was going off for some technical reason but we received the phone call and the alarm sent the police to our house. It was a big mess but the only time that ever happened and considering the rest of the time our customer service was exceptional so we kind of over looked the one bad experience.
My family has been using ADT while I was growing up (guess you could say I was born and bread white and blue) so I ended up following in their footsteps and got it for my own home whether that was the best deal or not I don't know. Installation process was quick, the guy really wasn't here for too long at all. The "smart" option is a bit confusing and I wish it was explained a bit better, but in time I'll figure it out. I can truly say they are one of the better security systems out there.

Like all home security companies, ADT offers a number of different packages to choose from. In addition to monthly monitoring costs, you also need to consider equipment costs, activation fees, installation costs, and the extra expense of any upgrades you select. Because ADT offers so many options and upgrades, it’s easy to end up with a customized ADT package that is more expensive than its competitors. Just be sure to keep a tally as you work with an ADT security pro to put together the right package for your home. If budget constraints are a factor, let your representative know up-front how much you can afford.
On the service side, however, ADT has been highly responsive. Support will attempt to fix your problem over the phone, including having you march through the house looking for panels and sensors to tweak, but if they can't help you resolve it within 15 minutes or so, they tend to default to sending someone out. All the technicians they've sent to my house since installation (three of them) have been prompt, courteous, and seemed to know what they were talking about.

We’re big fans of mobile access because it’s what home security is for—knowing your home is safe at any time and doing something about it when it’s threatened. Most companies now allow you to control your system this way from a keychain remote controller, mobile device (iOS or Android mostly), or web-based app for ease of use and distant check-ins.
He is slow and dumpy and from the beginning he acted like he did not want to be there. The job was really quite simple, simply install 2 cameras. I wanted to discuss the plans for installation but as we discussed the job, Mr. Lee got really impatient and rude. Soon he SNAPPED and Mr Lee WALKED OFF THE JOB!!! on the way out the door Mr Lee told me to "SHUT UP!" Really! I could not believe it. Mr. Lee wasted another hour on the phone in his truck and then drove all the way back to the East Bay.

When I got divorced and moved into a new home with my two young boys my parents purchased me an ADT security system. I didn’t think it was necessary, but I’m so grateful now. I don’t have to worry about putting my kids to bed and thinking “what if”. ADT monitors all of those what ifs. We are all safe at night and when I come home to an empty house with my boys in the evening I can feel secure that my house is as well. Thanks ADT and mom and dad.
The agent lied to me when I specifically asked upfront about termination policies. She said I could cancel the policy anytime and didn’t reveal termination fee. They can lie anything to rip a big chunk of money off you. Each time you call customer service or loyalty department, you get different answers and they never get back to you when you leave a message. I have had many services as I frequently move to different states, this is the worst available out there.

I had ADT for a couple of years. I did not have any issues but then again I did not have any break-ins. I wish that I would have gotten a security system in my apartment as it has been broken into twice now. ADT was easy to use, easy to pay for, which for me is a HUGE bonus. I like being in full control of where my money goes and when and this was the case with ADT. Being able to go online and change things as I see fit. The customer service reps are always efficient and polite although the hold times can get ridiculous.
If you do provide your address to the receptionist, the sales consultant will work to put together a security package and schedule a technician’s on-site visit. During this walk-through, the technician will provide recommendations on ways to improve your security solution with additional features. These upgrades and additions fall outside of the initial price of the system, so carefully consider the additional cost and value to you before signing the agreement. Once the paperwork is complete and you’ve signed ADT’s three-year service contract, the technician will install your system. After the initial 3-year period, your contract will renew on a month-to-month basis. To cancel, you will need to provide 30-day notice of intent to terminate.

With my setup, there are two external IP video cameras, namely the single unit from ADT that came with my system and is mounted above the garage, and the video cam installed in the Ring Video Doorbell, which the ADT technicians deliberately placed in such a way not just to record anyone in front of the door, but also to let it act as a backup viewing angle to the one mounted over the garage, just from the other side of the yard.
The Nest Learning Thermostat also requires a separate account with Nest, but unlike the Ring, you can control it with the Pulse mobile app or your web portal even though it's not directly connected to the Z-Wave control. This lets you change temperature and activate or deactivate heat or AC. You can read about the details of the thermostat in our dedicated review, but in brief, it's a slightly expensive but excellent device that not only simplifies your heating and cooling, it also learns your living patterns over time and will adjust your HVAC accordingly for peak efficiency.
