The story: Founded in 1874 by Edward Calahan. They started out as a messenger/alarm service but quickly added fire and local authorities. In 1909, they were purchased by AT&T (a name you surely recognize). Shortly thereafter, AT&T sold ADT again. Fast forward some years to 1969 and ADT went public. In 1984, the were renamed and ten years later passed their one-millionth customer. In 1997, Tyco International Ltd. bought them out and since then they have acquired dozens of Ma & Pa security companies as well as big ones such as Brinks and Broadview Security.
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.
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.

Most SimpliSafe customers report high levels of satisfaction, though SimpliSafe’s customer service is pretty unremarkable. There’s not a lot that stands out, but there’s nothing really wrong with it either. It’s just kind of there. SimpliSafe does do a great job, however, in presenting customers with a product that is so easy to use that there’s rarely a need to contact customer service in the first place. This creates a positive experience by itself, especially for a DIY system.


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.

I work for a company that uses ADT in our office for security. We had trouble with a couple sensors for which an ADT tech came to fix. Whatever he did completely messed up the system. We were without an alarm system for over a week because they didn’t have any techs that could come till then. Why do they not treat this as a necessity much like someone that is on 24/7 to fix your furnace if it goes out in the winter. They didn’t care that the office was with out security for over a week. As far as I’m concerned a security company that doesn’t care if you don’t have security is useless. ADT is useless. I’m looking in to Frontpoint to replace ADT in our company. My warning to those seeking ADT for your home. If they don’t care about a business they aren’t going to care about your home.
Terrible sales, installation, and service, especially for someone providing such critical installation and monitoring. They're great at acting nice, then following up with nothing or (at best) a bait-and-switch with extra charges, going back on their word, and requiring that you pay more money to get what was sold on the front end. I read the promotion fine print, read the contract, discussed with the technician and branch manager to clarify all the pieces. Then got passed through no less than two disjointed and loosely affiliated call centers which continued to require additional forms, contracts, and payments in order to get the original payment terms and rebates that drove the initial sale. You should pay more for service from a different company, because ADT will end up costing you more before the dust settles.
Hey Steve., Your right that the Pulse app is a big selling point for most customers. I think what she meant by that is that when the app isn't functioning; your security system still is and monitoring is working. That is the core and luckily during the Pulse app updates the primary function (being monitored 24/7 by ADT) is still in LIVE mode. Thanks and best of luck, we have heard it's back to working smoothly.
It was the most recent technical problem that convinced me that using ADT was a big mistake. When we installed our system, we added a new feature to automate the garage doors (this was brand new and NOT using any of the old equipment left by the prior homeowners). After about 3 months, one of the garage doors went “offline” and couldn’t be reset. The technician that was sent out replaced the associated equipment, and iit started working again. A few weeks later, the second garage door went offline and couldn’t be reset. This time, the technician that was sent out informed me that my garage door opener brand is incompatible with ADT equipment and will continue to short circuit and burn out as a result. There was no recommended fix for this problem, and that ADT only learned of this issue about a year ago. However, this equipment had been installed only a 3 or 4 months prior, so I do not understand why ADT would have allowed this installation if they knew about this issue. Nobody has been able to explain why they moved forward with the installation, so my conclusion is that it resulted from ADT’s inability to communicate with their sales force and technicians (keep in mind that the technician that came out to service garage door #1 wasn’t aware of this situation, while the technician that serviced garage door #2 DID know).
We live in an area with relatively low rates of home invasions and break ins so who is to say whether or not the ADT sign and stickers really discourage potential criminals. We’ve never had a window break or excessive heat, or even needed to connect with customer service so I can’t really say how they respond, or how accurate the system is, unfortunately.
Before they contact the authorities, the monitoring company has to make contact with you. If you don’t answer, they call a backup contact first and will contact the authorities if that person doesn’t answer. If you do answer, it’ll be up to you to determine if you want the police sent to your home. Police response time may vary depending on how busy the police department is.
YES! There is always an ADT special. Not only ours, but our price match policy assures that if you do see a better ADT discount out there, be it an on-line offer or in writing, when you bring it to us, we'll match it. So whether your question is: Is there an ADT special offer? or just how much is ADT? The answer is we've got a great value for you. Check these ADT special offers out:
We have been very grateful for the last two years having ADT in our lives. We had a situation and then we contacted ADT and we feel so much more secure. Whenever we have a question, they are so wonderfully pleasant to talk to and to figure out everything. Someday soon we would like to give an "ADT contract" to our daughter, son-in-law & children.... Big thank you!!!

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.

Protect Your Home’s third plan is called ADT Pulse Monitoring. It costs $52.99/month, or around $13/week. In addition to everything in the previous plan, ADT Pulse Monitoring also includes Home Automation. With home automation, you can use the ADT Pulse App to stay connected to your home security system anywhere at any time. Arm and disarm your system, monitor your home and receive real-time updates and notifications while away from home.

I had a representative from one of ADT's subcontracted sales companies come to my house last year in August. He gave us a whole spiel about how if he could put a sign in our yard we could get a security system for free. My husband and I both specifically asked him how long the contract was for for the monitoring monthly fee and were told that it was 1 year. We specifically asked what it would cost it us to cancel after a year and he told us it wouldn't cost us anything. He told us that when a year was up we should call and tell them we were going to switch companies and they would lower our monthly payment or we could just stop it anytime after a year.
What makes the best home security system comes down to the experience that a home security company provides. A good company will show genuine interest in providing you with a solution that fits your needs. This means it won’t try to upsell you on unnecessary equipment, pressure you into spending beyond your budget, or hit you with hidden costs, policies, or other unwanted surprises after you’ve signed a contract. It should simply give you peace of mind.
“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
Frontpoint’s DIY installation process was surprisingly user-friendly. Because it’s a wireless security system, there’s no drilling required to run a phone line, making the process less invasive. A personalized mobile website walks you through how to get the control panel connected and online, how and where to place your door sensors, and what to do if you get stuck.
Average contracts: Customers sometimes complain that the 36-month contracts for ADT monitoring are too long. We should point out that a 36-month contract is fairly standard in the home security industry. However, customers who care about shorter contracts with more flexibility could look into other companies. For example, Vivint customers who pay for all their security equipment up front don’t need monthly contracts, and Link Interactive offers shorter contract options (starting at 12 months).
If you move into a place that has ADT security already installed, just pay the $19.99 activation fee with ADT. The only problem is you might have equipment that is no longer compatible, considering ADT has largely grown by acquiring other companies. The only way to know is to call ADT for a free consultation—or as we like to think of it, free advice.
Wow,  I am blown away here. Did anyone read the ad you got in the mail, on the internet? Did you listen to the recording when you called in? It say’s free setup of 2 door sensors, 1 motion sensor and 1 keyless remote. NO WHERE does it say they cover all of your windows extra doors ect at no extra charge. These are all upgrades you can add to your account just like a smart phone VS a little flip phone or a neon VS a viper. You pay for what you get. You are getting 99 dollars worth. They have to pay for the parts, pay the installer pay for the advertising ( That flyer you called in on is not free)
A new ADT Customer will be able to take advantage of its lowest monitoring plan (Traditional) at $28.99 per month, however, this plan does not come with free equipment installation or the extended limited warranty. You will be required to sign a 36-month monitoring contract (24-month if you are a resident of California) which is unfortunate if you become dissatisfied with the alarm system after the 6-month money-back guarantee period.
This unit is constantly losing connectivity with its connected sensors, even if it's right next to them (I moved them all to be together for several days to test this). In addition to the complete loss of being able to know when there's O2/Fire, the hub only notifies you of a loss in connection at around 2 am the next morning, regardless of when it lost the connection. This is a super annoying series of beeps that continues until you get out of bed, put in your code, and tap through all the menus to tell the hub to "ignore the problem." No matter how many times you do this, this exercise is repeated several nights a week. You also cannot change the time or date on the device unless you have an ADT professional install it (what??). I finally sent it back and got the combination Samsung Smart Things hub and Nest solution which was way less expensive, way easier to set up, way nicer-looking and is way more reliable.

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.
