ADT home security systems are backed by more than 145 years of experience. As the leader in home security, ADT can help you customize a home security system with easy-to-use equipment and special security features to meet your safety needs. We have service centers nationwide that can install an ADT home security system within 24 hours in most areas. Once your home is equipped with our top-of-the-line system, it is connected to a network of ADT Monitoring Centers nationwide which deliver non-stop security monitoring 365 days a year. All of our installation technicians are internal employees, and not third-party contractors. You can count on your Security Advisor to take the time to set up your system properly, help you understand how the system works, and help make sure your home and family are thoroughly protected.
"The alarm, when it goes off, is very loud!!! This is a good thing. If we ever need to activate it, it will definitely scare off anyone trying to come into our home. We can set it off from our phone or from the keyboard control panel that we installed in our bedroom. We feel very safe with this purchase."

"I’ve had nothing but problems with SafeStreets. The installation was a mess—took hours longer than promised, and the technician seemed clueless about the system. When I called customer service, they were rude and unhelpful. The security system itself is glitchy and keeps going offline. Definitely not worth the hassle."
