Millions of people use ADT alarm systems to protect their homes every day. It’s by far the most popular provider in the nation. But what makes it so popular? ADT has been around longer than any other security company, with 140 years of experience. It uses locally authorized resellers to sell and install its products, which allows ADT to cover more areas of the country. It’s also got multiple monitoring centers running 24/7 to help prevent any kind of service outage. That’s not to say other companies don’t do the same thing; ADT just does it on a larger scale. Because of the local vendors, your experience with ADT will vary greatly based on your location.
ADT supports a range of other security cameras including indoor cameras should you want one, so you can talk to your technician about different options if the base cam doesn't suit you. Overall, it's been fine for my needs and I'm considering installing another external one at the rear of the house. This is something that'll require a call to ADT and an installation and service charge, but after that, the cam will be fully integrated into the Pulse system. You can even install your own hardware, if you like, though your mileage will vary as to how deeply you'll integrate with ADT's software without help from a company technician.
I have always wanted to keep my family and home safe, especially at night. I do not have a guard dog like some of my friends do and I do not find dogs effective. So I decided to do some research and found ADT to be the best choice. They came and thoroughly installed the sensors all throughout my house. They made sure to test the system to see if it was working properly. After that I am pleased with my security system. It is easy to use and we have never had a problem with it. Also, the staff are very friendly. If we have questions they always help us out. We have been safe in our home ever since (no more burglaries).
I have been an ADT customer for 15 years and 2 weeks ago I found out my alarm was not communicating with them so I called for repair. They told me nothing was available for 2 weeks so I set a date and was told someone had to be home from noon until 5PM. Appointment day at 4:14PM I call them and ask where the tech is. They have no clue and tell me they will reschedule for another 2 weeks out. I tell them to cancel my service and then they tell me I WILL OWE THEM FOR 30 MORE DAYS OF MONITORING after shut off. It doesn’t work – they fail to honor the appointment they set up and they want me to pay for 30 more days? Of course there is no supervisor available to talk to me but they could have one call me back in 24 to 48 hours. What an unethical unresponsive company. Never do business with them.
“Was having a lot of trouble signing in on my Pulse account. Had to use it every time. Called and talked to 3 people about this problem. All they could tell me was to reboot my phone. I did so. On the 4th call I talked to a man and he told me that ‘When you did the last upgrade the this was a existing problem.’ Said that the company has known about this and was trying to fix it. Just forget that the emails I was getting telling me that my phone was LOCKED UP to just forget it and when the next upgrade comes it should be fixed. Why did it take 3 people who didn’t know about this problem and 1 that did.” – Kenneth, August 10, 2017, Consumer Affairs
I had a horrible experience tonight. I was home by myself with 2 small children. My flue lever broke, but I didn’t realize that. The house filled with smoke and the fire alarm went off. I put in the code multiple times to stop it. When I called ADT to stop the alarm (1 child was crying due to the noise), and it wouldn’t stop, the first man to answer tried to help...but he couldn’t shut the system off. He put me on hold! The second girl basically told me to rip wires out of my electrics to shut it off...first in the chaos...she told me I had to find a screwdriver!
The SimpliSafe system requires a professional monitoring subscription to receive alerts. That’s because it relies on a cellular connection rather than internet, so someone needs to send you an SMS text. There’s no option to receive automatic in-app alerts. You’ll have to upgrade to the $25-per-month plan to save yourself the task of keeping a constant eye on the video feed. (That’s still $10 less than Frontpoint’s cheapest plan, though.)

ADT doesn’t have the strongest customer service reputation among the companies we considered, racking up more than 3,000 complaints on its Better Business Bureau page. While we chalked most of this up to the fact that ADT has several million more customers than its competitors, our tester began his call with low expectations. He was pleasantly surprised, saying, “My needs drove the conversation. And once I finally had the quote, he explained the purpose behind each device I was receiving and what the installation might entail. He took extra time to help me weigh whether I needed home automation or not — and I’m almost positive it wasn’t scripted.”
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.

A smart home security system connects to your Wi-Fi network so you can monitor and control your security devices using your smartphone and an app. Entry-level systems usually include some door and window sensors, a motion detector, and a hub that communicates with these devices using one or more wireless protocols such as Wi-Fi, Z-Wave, Zigbee, or a proprietary mesh network. You can add extra door, motion, and window sensors to provide coverage for your entire house and build a comprehensive system that includes door locks, garage door openers, indoor and outdoor surveillance cameras, lights, sirens, smoke/CO detectors, water sensors, and more.
I am very upset with my ADT experience and contract. Your sales rep Daehan ** gave me inadequate information regarding your ADT service and contract. I was very upfront and concerned about switching from SafeNet to ADT because I was planning on moving the following year. He ASSURED me that the move of equipment, install and monitoring fees would not incur additional charges! He also did NOT disclose that there was a 36 month contract or an early termination fee. If I was properly informed of incurring additional charges for my move, I would NOT have switched security companies as my contract with SafeNet was complete. In order for me to set up a new security monitoring system at my new place of residence, I received an estimate for $461.
I signed a 3 year contract with ADT and while the did provide security services it was at a high cost. Apparently the original quoted price was a promotional price because every few months my bill went up and up and up. By the end of three years I was paying almost double the original price. There was nothing I could do because it was extremely expensive to break the contract. I have learned my lesson and wont do that again.
SimpliSafe does take a much more basic approach to security than the rest of our top five. You aren’t going to get as many bells and whistles with a SimpliSafe system. In fact, it doesn’t even use a control panel like other alarm systems. Instead, you get a central hub and tactile keypad. It’s a little old-school, but SimpliSafe is more of a function-over-fashion kind of system anyway, and it helps keep prices low.
Your review helped a lot for deciding in favor of ADT as my home security system choice. I was unable to decide which one to go with as I was contacted by many companies after I gave into an ad online. Then my friend suggested me to check out your site. Here, I saw the reviews of all those companies which approached me and after measuring the pros and cons of each one, I decided on ADT. Thanks for your very well researched data.

When my contract with ADT expired, I contacted the company to disconnect my service, which they did, but they continued taking the monthly payment from my checking account. When I contacted the company, they advised that they owed me $424.23, and that they would reimburse. That was EIGHT years ago, and I haven’t gotten a cent. I’ve contacted the company numerous times, and they give me different stories each time. They’ll tell me that they sent the money to Illinois unclaimed funds- which they hadn’t, I checked. Recently, I spoke with a representative of ADT, followed up by a manager. The rep stated that she has numerous notes showing my attempts to get MY money back. The manager basically said that I was owed the money, and after a brief hold, advised that they owed me nothing. It’s been 8 years!! I think I’ve been more than accommodating. I’ve also kept notes, recording dates, times, names, and the info discussed. ADT you’re the theif that I need protection from.


I have had ADT security for almost 2 years now. I bought the system to help protect my family after a home invasion. After 1 year of service, we moved and chose to transfer service to our new house. We had a technician come out and perform the installation and once that was complete we started using the system. A year after transferring service to my new home, I had an issue with the keypad. I called my local ADT office to have them come out and repair it, only to be informed that they never actually transferred the service to my new address!

There are two types of glass break sensors: shock sensors and acoustic sensors. Shock sensors detect vibrations when glass breaks or shatters, while acoustic sensors are designed to detect the exact sound waves of breaking glass. Both are efficient, but the acoustic sensors can monitor a wider area, such as large bay windows or sliding glass doors.


The rating rang true when we became Vivint customers ourselves. Our tester felt like the installation technician was a guest in his home — he even came prepared with protective shoe covers and asked to borrow the vacuum to clean up the drill debris. The Vivint tech was also upfront after he noticed that our tester had ordered more equipment than he needed. As our tester explained, “I originally asked for an outdoor surveillance camera, but after reviewing the house, the tech felt the doorbell camera was sufficient. Turns out, he was right.” That ended up lowering our tester’s expected price.
New service phone calls to the company may result in a transfer to a company known as Protection 1. Earlier in 2016, ADT announced its acquisition by asset management company Apollo which also owns Protection 1. The two companies, in essence, are now “merged”. Protection 1 serves customers out of ADT’s service region, and vice versa. However, ADT may not mention this relationship before transferring you.

I give them 3.5 stars out of 5. Their equipment is the only thing lacking to me compared to what I have seen with some of my friends but I also haven't upgraded to the new Pulse system yet so I can't really judge apples to apples. I do feel safer with ADT and had them 2 years now. Does anyone know if they offer infrared motion detectors with camera in them? I have seen these advertised but don't really know where to get them. Also, what are the add on costs for more equipment?
Although we always recommend choosing a professionally monitored home security system, we understand that isn’t the right choice for everyone. If you’d rather handle the installation and monitoring on your own, consider one of these DIY alarm systems. And for more ideas about how you can protect your home yourself, check out our article with DIY home security tips.
ADT Home Security systems are very user-friendly, and during installation, the technician will show you how to use the equipment. There is technical support available to answer any questions customers have about the equipment. ADT offers professional installation, several monthly plans with competitive rates, and allows users to choose between wireless and hardwired systems. Overall, ADT security systems are the most reliable and the most popular in communities throughout the nation. Keep in mind, though, that customers must sign a three-year agreement for all ADT security monitoring plans.

1 week ago I agreed on the price I would pay monthly for the alarm service with ADT. The installer came today and the prices of what we had talked on the phone were very, very different, but the surprise was that when the installer came to my house she began to uninstall the existing alarm system and after all that she tells me that the price was different from the one I had agreed on by phone so therefore I canceled the service and had the old alarm system reconnected
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.
I had the standard alarm system for my house. There were several reported criminal activities in my neighborhood with loss of property and sense of safety. I called ADT to upgrade my system for many reasons including I was going away with my family and it was time to protect my property.They came out and installed sensors and a camera so I could take a quick look around the house from anywhere on my laptop.I can leave home without fear that the alarm will alert the police and I can take a picture of any unwanted intruder in the house.

Then there’s the monitoring service – they offer $27.99/mo but that’s only if you have a land phone line in your home. Including the warranty on the equipment that is supposed to be $36.99, but again they claim it’s only if you have a land line. I know others who have the service without a land line paying $36.99 no problem, yet ADT claims they don’t do that. Total garbage and lies. So now the monthly monitoring fee is up to $48.99 for wireless. However if you speak with their customer service, they will bring that down to $44.99/month and offer $300 in gift cards to make up the difference between the $48.99 and the $36.99 as promised. It’s all such a set up.


With a founding date of 1874, ADT is probably the most mature player in the smart home security market. While it's still building the home automation portion of its services portfolio, its Pulse system is both secure and sophisticated. But while the company does a great job treating its customers well on a service front, it's important to note that the Pulse system is neither DIY or cheap.
ADT Motion Sensor Protection embeds advanced safety methods into your home security system. From infrared to magnetic technologies, you can ensure your home security system is working around the clock. These wireless devices transmit signals to the control panel via radio waves, helping provide an extra layer of protection ensuring there are no wires for an intruder to cut. Motion sensor systems are battery-operated with strategic alerts to signal the control panel when running low. 

It’s important to do thorough research to find the best home security unit for your needs. Of course, the great news is, you’re not alone. You can learn a lot about home security systems based on other buyer’s experiences with several leading brand names. What’s right for some buyers may not be the best fit for others whose homes and businesses pose unique challenges and possibilities. Therefore, it’s important to pay close attention to the pros and cons which most closely affect your lifestyle, financial situation, time limits, etc.
To make sure you’re getting the best-value system for your money get quotes from up to 5 companies first. Ask each of them to do a risk assessment on your property to see what areas of security need addressing and why. This on-site inspection should be free of charge. Never accept a company who says they don’t need to visit your property to do an inspection.
