purchase a system from ADT 7/17/2011

I think many folks who purchase a system from ADT should first call up Corporate at 877-536-0433 and see what the best current deal is directly with them as opposed to just a random licensed distributor. You might even get a better deal with going directly with ADT. more

this saved my girl 5/1/2011

ADT's critical conditions system saved my daughter’s life! My daughter was home alone and left some dinner heating in the oven. The heat from the system triggered the alarm to go off and within minutes a fire truck was on its way to our house. more

Cheapest 4/29/2011

Safewatch Quickconnect package is the cheapest for the installation and all. We have this one and up till now we like how it works. We never had false alarms or break ins yet and I hope never in the future. more

Concentrate Working 4/25/2011

The alarm system that was installed to our house last Monday is great. There are changes in terms of feeling secured with the system. We can sleep better at night and when we go to work, we can concentrate more on working. Thank you ADT! more

Widely Used 4/11/2011

ADT is the best company when it comes to security. They have a lifetime warranty on all equipment, 36 hour service call response time (try getting those other companies to do that) world class service!! what do you expect? ADT is securing the White house, The Pentagon, and Fort Knox!! Everyone i have talk to that has ADT (about 100 people) has the same feeling about this great company. remember, people only like to talk when they have a bad experience, very seldom do people share their good ones. Thats the only reason these other reviews are bad, not because ADT is a bad company by any means. more

Thanks to the Camera 4/8/2011

We have a big backyard and we put up one security camera there. One time, there was this strange looking person who keeps on peeping from our fence and thanks to the camera, we get to report him and he never came back. more
