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."

Home Security Systems questions, answered by experts

A deadbolt is one of the most secure locks you can install on your front door, so it is better in terms of home security than other types of locks. While deadbolts are typically more expensive than a regular lock, they’re still quite cost-effective and provide an additional layer of security that may even deter some intruders.

Window security film won’t prevent break-ins or stop your window from shattering from impact during extreme weather like hurricanes or tornadoes. However, applying security film is relatively inexpensive, and it can make breaking into your home significantly harder—often hard enough to deter burglars entirely—and keep your window from shattering on your floor after impact. For these reasons, window security film is often a worthwhile investment that helps protect your property.

Costs depend on system type, labor rates, and additional features like smart integration or professional monitoring.

Security camera prices vary widely, with individual cameras typically ranging from $125 to $450 on average, not including professional installation costs. The camera's quality also impacts what you pay. Expect to pay more for desirable features, including a resolution of 1080p or higher, a field of view over 110 degrees, and enhanced night vision. Remember, your out-of-pocket installation cost will increase significantly when purchasing a complete system to cover your property inside and out.

Faulty sensors, weak signals, false alarms, and control panel malfunctions are common problems requiring repair.
