I am a home automation enthusiast and a DIY guy. When I started out with home automation, I was using the open source OpenHAB for my hub. This was nice for having everything localized, but too get anything to work was a chore and I spent most of my time messing with the system rather than enjoying it. I was looking for a mature system that would give me a lot of the benefits that OpenHAB gave me without all of the time spent on configuring it. I was also looking for a decent home security system to incorporate into the home automation system. That's when I found this product, ADT is the name I trust when it comes to home security and the SmartThings Hub was always ranked #1 in all of the reviews I read.


Their Pulse app control is what I like best. I'm sure there is better equipment out there but the app ties in nicely with everything. Can add multiple accounts, see a log history of when the alarm system was turned on and off and by who. Can take a peek at the cameras during work to ease my mind that nothing is going on at home that I should be aware of. Good deal for $55 a month, a lot better than getting with a local company like I've seen my neighbors do just to switch to ADT a few years later.
If you’re renting or leasing, it may make a difference in whether you want a wireless setup or not. Wireless systems don’t require drilling, which your property owner may appreciate. But if you do end up needing to drilling, here’s a fun fact: in most cases you need only verbal permission from your landlord, so you won’t have to come up with a written agreement or anything like that.
One of the drawbacks of opting for GetSafe’s month-to-month contract is that you have to pay for equipment upfront. GetSafe’s one- and three-year contracts include the starter kit for free, and its three-year contract also includes a bonus hardware credit of $250. The starter kit costs $249 and, even though it’s less expensive than other providers’ equipment packages, it could be too pricey if you’re on a tight budget.

SimpliSafe doesn’t require contracts, which tells us that it is confident in the service it provides and doesn’t need to lock you down. SimpliSafe offers low-cost cellular monitoring starting at $15 to $25 per month depending on whether you want mobile access. The only company with a similarly low monitoring cost is Scout, but it doesn’t offer the same range of equipment that you can get with SimpliSafe.
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).
J comes in and starts looking around and does his ultimate security evaluation which would cover every window door and crack in my house against burglars.  $5,000 to cover all of that.  I said no and he went down the list to cover just the downstairs, then the back of the downstairs, then just the doors. This was the second issue of his high pressure sales tactics “I’m not trying to scare you, but…” That’s exactly what it felt like he was trying to do.
I really like the upgrade to their Pulse smart phone control app. It makes everything much easier. Got rid of the old crummy control panel, got a sleeker one and put it in the closet and then setup sub accounts for my kids and anyone I want to access the home security system. I don't feel ripped off by their pricing although I'm skeptical that it really costs $50 a month for monitoring. I suppose they need to make their money somewhere and this is where they do.
Are you considering an ADT security system but are curious how they stack up against other security providers? If you’d like to see a heads up comparisons of ADT and other companies that made our best home security systems list visit our ADT Versus pages. You can find links to these below. On these pages  you’ll find comparisons of both companies equipment, pricing, features, and key differences. If you’d like to save yourself some reading you can also scroll to the bottom of the comparison pages to see who was the winner.
The Canopy Mobile Panic service will work differently with different products. If you pair the service with a Ring Doorbell, you will still be responsible for monitoring the device, but will have ADT’s support. For example, let’s say someone rings your Ring. You check out the event, you don’t like what you see, you press the panic button, and ADT will call the police on your behalf. If you connect the Panic Response Service to your Samsung Gear S Smartwatch, you can use the watch app to press a panic button at any time to be connected to the ADT monitoring center.
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.

While most providers give you the option to add both indoor and outdoor cameras to your security package, SimpliSafe’s selection is limited to one indoor surveillance camera. The camera includes features like free streamable HD video and audio, 30-day storage, and night vision, but it doesn’t take snapshots of activity and can’t pan or move — basic features found on most surveillance cameras.
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!
I recently received a flyer in the mail with my change of address forms from the post office with an ad for Protect Your Home advertising a “free” alarm system with 5 wireless sensors, motion, panel, and key fob with the signing of a 3 year contract.  I thought, “Great!”  I called the next day and spoke to a very polite sales representative and his manager and was set up to get an alarm installed that very afternoon.  I specifically told him, his manager, and the scheduler that I would not be available until after 4pm.
Frontpoint captures the best of both DIY and do-it-for-me worlds, with self-installation and sophisticated equipment line-up coupled with professional monitoring. We built our package uber-cheap — a control panel, glass break sensor, and four access sensors costs as little as $100 upfront. Then we installed and arranged the system, and let professional monitoring services take care of the rest.
Actually, Jean's concerns are valid. I had spoken with ADT about this recently after purchasing their cameras. Apparently, the cameras are motion-activated and will only record for 30 seconds. Afterwards, the camera goes through a 4-minute resetting period before it can record again. Technically, an intruder can walk into a camera's view (thus activating the camera) then walk away and wait 30 seconds for it to finish recording. Afterwards, the intruder will have 4 full minutes to do whatever they want before the camera starts to record again. That's plenty of time to break in and out, and the only clues you'll have is footage of someone walking by. I ran this scenario by an ADT rep and they were stumped. The rep than told me that ADT does, allegedly, offer cameras that record constantly, but they require additional equipment and cost upwards of $350 per camera. Sorry, not gonna happen. For $350, I can buy 4 cameras at Home Depot and have them stream to an external hard drive. Don't get me wrong, I love ADT's window and door monitors, but the cameras are for the birds. I'll be replacing my ADT cameras with third party cameras that actually record 24/7.
If for any reason you’re unhappy, you’ll get a full, hassle-free refund* on installation and monitoring. *Subject to certain restrictions If during the six months following installation ADT is unable to resolve any installation/service-related concern, you may receive a refund of the installation price and all monitoring fees you paid within the first six months. Certain restrictions apply.

I am extremely disappointed with my most recent encounter with an ADT technician by the name of John C. for starters I greeted him kindly and he completely ignored me as if I was speaking to someone else in the room . Upon him asking me what issues I was having with my system, he kept cutting me off stating we were using the system incorrectly, and raising his voice at me to the point he was practically yelling at me answering me in a scornful manner. For someone whose job consists of interacting with other people and in this case required going into people’s homes where they are supposed to be helping a person, his behavior was very rude and unacceptable. The equipment, security system and ADT Pulse has been great. Just had a rough start with the tech but I suppose not all of them are going to be like that, he could've been having a bad day.
The equipment included with ADT includes a control panel, keychain remote, three entry sensors, an infrared motion sensor, a high-decibel siren, a backup battery, and yard signs and windows decals. Customers can purchase an available system, or an agent can help customize the perfect system for your home. ADT customers can add safety accessories such as medical pendants and panic buttons that can make the elderly, disabled, or people with certain diseases or ailments feel better protected.

Depending on your needs you can go with a system that you monitor yourself, or pay a subscription fee to have your home surveilled 24/7 by professionals who will contact your local fire and police departments when alarms are triggered. You can even take advantage of on-demand monitoring services for when you're away on vacation. Of course, the more coverage you have, the more you can expect to pay.
The ADT Essentials plan for basic digital monitoring service has a limited lifetime warranty on parts and labor, something that other competitors do not offer. If you want additional protection, the Essentials Plus package includes 2-way voice monitoring. Like all plans, this one includes monitoring for police, fire, and medical emergencies. However, both plans require customers to have access to their own landline phone.
I had service with ADT for a number of years. During that time, I had one minor kitchen fire and incorrectly entered my alarm code one time. I was able to put a lid over the pan to extinguish the fire, but ADT called almost before I had done that. The night I entered my security code incorrectly, I went straight into the shower and didn’t hear them calling. (Living in a condominium, I had a silent alarm.) By the time I finished my shower, the police were at my door.Fortunately, those were the only two times the alarm went off, but I was impressed with how quickly ADT responded. I had shopped around before getting the system installed, and they were also offering a very competitively priced package.
I have been with ADT since 2004. I work out of town and really like the peace of mind I get with ADT protecting my home. The only call I have had since 2004 was during a storm. It appeared that the storm set off the alarm. My only complaint is the monthly fees. There have been small increases in fees over the years, never more than one dollar. I received a letter that they are increasing the monthly fee by $3.00 next month. Are they upgrading my system? No. Has there been an increase in alarm activity on my system? No. I guess they need the increase to give an executive a pay raise. Well, they have raised their fees out of my house. I am now going to find another security firm that appreciates long term customers. Good bye ADT.
I got ADT for some reasons most don't think of. I am a business man and I know it takes years and years to build and structure a working business properly. I bought the ADT alarm because they have several monitoring stations throughout the USA all with backup features in case they get hit with a natural disaster. Their support is also levels deep in security and these are things you will not find in a review or hear about with newer companies. By them handling so many monthly customers has given them a reliable structure to handle big problems.
It's hard to beat the biggest and best. I started out with Guardian but worked my way over to ADT for practical reasons. Lots of companies aren't nation wide so if you have to move (like we do my husband is in the military) it is too much of a pain to try and get out of contract etc. My advice is go with a national company so you don't have to pay any early termination fees.
The installer came out and was polite and early. His manager showed up and seemed to rush him through everything. When setting up sensor they mis keyed motion sensor as door sensor which I caught later and had to have adt phone support fix. Then 24 hours later a window sensor fell off window. I reinstalled it and it functions as should now. When I paid for equipment I gave him credit card and I specified I wanted the monthly billing going to different card. He had both cards and whether he didn't enter is right or just didn't care it all ended up on one card. Low and behold a month later I have a hard pull showing up on my credit report. So now I have involved equifax credit bureau and have contacted defender security directly who was supposed to review things and get back to me in 24-48 via phone call and send letter via usps. After 5 days I had to call back to find out that they sent a letter and the person I was speaking to couldn't help me any further.
ADT doesn’t just monitor for potential break-ins, it also safeguards against hazards like carbon monoxide, fires and floods. Smoke detectors, carbon monoxide detectors and flood sensors can be added to your security system to monitor for hazardous conditions. The company even offers a variety of panic buttons that can be worn or placed in your home and pushed to alert first responders. Wearable and key fob panic buttons are also accessible when you’re away from your home.

ADT Pulse monitoring offers all the features of basic security and adds home automation into the mix, giving you power to personalize your system to your needs, whatever they might be. For anyone looking for more than just alarms and monitoring, this is the way to go. That way, you can add things like a video doorbell (Ring) or speech control with Amazon Alexa and Echo.
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.
Known for its innovative home automation features, Vivint offers professional 24/7 monitoring to homes across the U.S. Vivint’s cutting-edge technology includes add-ons like an intuitive smart thermostat, an indoor camera with two-way communication and a garage door control that lets you close it from your smartphone. One major pain point is that Vivint requires long contracts, which can be a problem if you don’t want to be locked into a long-term commitment. But, if you’re fine with a four- or five-year contract, Vivint’s worth a look.
There are many points at which a home security company can disappoint its customers. This may account for the large number of critical comments about ADT security systems. Customers complain about undisclosed fees, prices that are sharply higher than quoted, punitive cancellation policies, relentless upselling, incompetent technicians, malfunctioning and obsolete equipment, and poor customer service. A minority of commenting customers, however, are very satisfied with the service.
With a $49.99 per month Pulse package, you get all the basic home security coverage you need. You also get to control your system with a tablet, smartphone, or via a web portal. With the ability to remotely arm/disarm your system, set up email and text alerts, and create rules, ADT Pulse makes life easier. So, in short, is ADT Pulse worth the extra monthly fee? Yes, it’s worth it.

My experience with ADT was very bad from the beginning. After somebody broke into my house while I was sleeping I found necessary to get a security system. The first company I called was ADT, because it was very well rated on the internet. Over the phone, the person I spoke with told me that the equipment is free and I will pay between $28 and $58 a month depending on how I customize my package, and the installation time will be around 2-3 hours.
Nest Secure offers an innovative twist on common security sensors, packing multiple functions into its Nest Detect sticks that serve as both door and window sensors and motion detectors in one. These devices also add nifty features like Quiet Open—where you can deactivate a single door to let the dog out—and Pathlight motion sensor lights. It’s pretty pricey as far as starter kit security systems go at $499, but if you’re already heavily invested in the Nest ecosystem, this might be the perfect flexible security system.
ADT Security Services Customer Monitoring Centers help protect the people and things you value most, 24 hours a day, 7 days a week. There is a comprehensive network of five interconnected command centers strategically located throughout the United States. The investment made in technology - and the systems in place to back it up - illustrates a deep commitment to customers' safety and security.  
If This Then That or IFTTT for short, is a service that allows you to connect other services and applications together (using what IFTTT calls “applets”), letting you accomplish almost any task imaginable. For instance, you can use IFTTT to automatically cut off your phone’s WiFi when you leave home to save power. Just remember that if you use IFTTT to automatically disarm your system when you enter your home, your phone’s location service must be powered on. Otherwise you’ll get a loud surprise.
Backup System: If your power goes down or your phone line is cut, this backup system will kick in. Alarm systems also come with a backup system, which can keep your alarm going for up to 72 hours by using battery power. If your home uses Voice over Internet Protocol (VoIP) phone system, backup systems are crucial because a lot of alarm systems aren’t compatible with this. Alternatively, if you provide cell phone backup, this will allow the monitoring company to get in touch with you via this.
This would not be an issue if the reset time wasn’t so RIDICULOUS; 5 minutes!?! This might be acceptable for a cheap stand-alone camera, but ADT is supposed to be a SECURITY vendor. Its widely known any time you see a camera and an ADT logo on the house, you just need to toss something in front of the camera, and then come back 30 seconds later. You now have 4:30s to do whatever you want, and if that’s not enough time, just repeat the same process. How embarrassing to say the least.

ADT cameras do not pick up movement at night. I called ADT customer service and told the rep that thieves had broke into my car TWICE in the past five months. The ADT cameras are literally pointed directly at my car but there was absolutely no footage found by me or the police. The rep said that ADT cameras do not have night vision or infrared so the cameras cannot pickup movement at night. That is KEY INFORMATION that none of the ADT reps told me when they were so vigorously pushing there products and services. Then, just to check the response time for a call from ADT, I tripped the alarm to our house. It took someone from ADT 12 minutes to call. When I answered, the lady from... Read More
Hello Kai-We apologize for any issues that you encountered with the ADT authorized dealer. When you installed your services in CO, you would have signed and been provided with a copy of your residential services agreement, that clearly spells out the term of the agreement, 36 months. Should you have any further concerns, please feel free to email ADT at AlwaysThere@adt.com. Thank you. -Gabe
The worst service! I just moved in to my home not even 2 months and my home was broken into, I was told one thing when I purchased services and when Safe Haven their contract dealers came, it was something totally different. The burglar came through the windows cause no motion sensor where there, and the screen was broken to the main box! When the tech came out he told me I was not covered and I had to pay 400 dollars up front or buy 1100 dollars worth of equipment in order to protect my home that I pay them every month to monitor. Buyers please be aware! YOU ARE NOT PROTECTED BY THIS OVER PRICED SCAM COMPANY!!! DO NOT PURCHASE YOU ARE BETTER OFF BUYING YOUR OWN SECURITY SYSTEM
If we are counting rankings then my vote is 4/5. I just got them cause I felt I knew them best. My family had ADT growing up and so I followed suite. I didn't really compare it to other companies so can't say I know ADT is #1 or anything but the tech that installed our system did it quick and they showed us how to work it. Their pulse app took some getting used to as I don't really care for a "smart" home and I usually end up using the key remote they got me instead of my phone.
When it comes to home security I'm a basic kind of guy. I just want it to know if someone breaks in my house so I can have my gun ready and protect my family. I use ADT, it seems the most logical and they have treated me great. I moved once with them which cost a little money but they installed the new Pulse system at my new place since I was due for an upgrade to cellular anyways. I don't do the cameras etc. but I do turn it on and off from my phone and that is easy with their ADT app.
SimpliSafe’s wireless security system makes for a painless DIY installation. The keypad and sensors, for instance, are mounted with sticky pads, eliminating the need for drilling. Its step-by-step guide walks you through the entire process, making it relatively simple to follow along and get your system running in no time. And, if you get stuck during your installation, a customer service rep is only a phone call away.
Their Pulse app control is what I like best. I'm sure there is better equipment out there but the app ties in nicely with everything. Can add multiple accounts, see a log history of when the alarm system was turned on and off and by who. Can take a peek at the cameras during work to ease my mind that nothing is going on at home that I should be aware of. Good deal for $55 a month, a lot better than getting with a local company like I've seen my neighbors do just to switch to ADT a few years later.

The Samsung SmartThings ADT Home Security Starter Kit is compatible with both Alexa and Google Home, as well as Zigbee and Z-Wave communication protocols.

(Not compatible with NEST, Sonos, D-Link, and Blink devices.) Ensure every inch of your home is covered with the Samsung SmartThings ADT Home Safety Expansion Pack or add to your smart home with individual accessory devices such as the SmartThings Carbon Monoxide Alarm, SmartThings Water Leak Detector, and the SmartThings Smoke Alarm as you need them!

I had ADT come in and have their system put in my home I had just purchased. It took 3 hours to install. They had a promotion going on with a free ring camera. But keep in mind. The home when I bought it had a security system already hard-wired into the home. Which was working. I just needed to have a security company come in and take over the system. The salesman told me they would piggy back my system. They did exactly what they said. 45 minutes after the installation was done. I tried to arm the system. It came up with multiple error codes. I called ADT and the salesman who set this up. He said the tech who installed it will call me back in 30 mins. This was a Saturday. Well no call.
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.
I'm fortunate enough to live in a house I spent a lot of time in while growing up. It has an old security system that hasn't had service for years. I remember watching a crew of installers come and drill holes into doors, window frames, and fish wire through the drywall for the motion detectors. It took two people an entire day and many tools to install the now-archaic system.
Since buying this hub I am pretty happy with it. Still getting everything setup just the way I like it, but a lot less of a headache. I am having an issue with the battery being no good, but I opened a ticket for it and I am sure it's as easy as sending a new one out to replace it. It is a bit price, but I had ADT come out to give me a quote and just for the bear minimum it was about $1200. So, $400 is not too bad from that point of view and also no long-term contract. I can start and stop my monitoring at any time. I also got all of my sensors and motion detectors at 50% off during a sale so that was pretty good too.

Frontpoint captures the best of both DIY and do-it-for-me worlds, with self-installation and sophisticated equipment line-up coupled with professional monitoring. We built our package uber-cheap — a control panel, glass break sensor, and four access sensors costs as little as $100 upfront. Then we installed and arranged the system, and let professional monitoring services take care of the rest.


We’ve been extremely pleased since our switch to ADT. Our business is attached to our residence, and our alarm system covers both office and living spaces. With two keypads and several trigger spots (doors, windows and a motion detector), we are fully protected at all hours of the day or night. We’ve had a few technical glitches, but our local response service has been very efficient in fixing the problems. And always so friendly!
Actually, Jean's concerns are valid. I had spoken with ADT about this recently after purchasing their cameras. Apparently, the cameras are motion-activated and will only record for 30 seconds.

Link Interactive offers 12-, 24-, and 36-month contract options, which makes it great for renters and anyone who isn’t ready for a long-term commitment. Alarm monitoring prices start at $31 and go up to $41 per month, making it more affordable than Frontpoint or Vivint and one of the more competitively priced professionally monitoring services on our list.
The most common type of motion sensor is the infrared sensor. These sensors emit infrared light and are triggered when they detect body heat. They identify intruders by comparing the heat of inanimate objects with the heat of anything moving in its field of detection— like a human. Many motion sensors are designed with Pet Immunity to avoid false alarms being triggered by small pets in the home.
