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

Some Christmas lights are marked as being “UL Safety Certified” or Underwriters Laboratories Safety Certified. This lab is a trusted source for determining the safety standards of electrical products—you should make sure your Christmas lights have this label. Brush up on other electrical safety tips before installing any lighting features. 

You should be able to use your smart doorbell and access your video feed without a subscription. Subscriptions give you special features, such as night vision, downloading, and automatically saving footage for a set amount of days. It’s a good idea to compare plans among different providers before you commit. 

Thieves can open almost anything with enough time and the right tools, but they also prefer easy targets that are unlikely to get them caught. Forcing open gates is loud and difficult, and to be able to open one electronically requires extensive knowledge of the system, which most thieves don't have. Electric and other security gates are great deterrents because the thief will move to an easier target. If the thief is determined to enter your property, they will most likely find a different entrance point.

Changing the alarm in your wireless security system is a perfectly reasonable DIY task that most people can complete on their own. Simply open the system’s control panel, remove the existing battery, and replace it with a new one. If you’re using a wired system, this may require disconnecting and reconnecting both the positive and negative wires attached to the battery, and you may want to call in a professional to help. 

It is possible to spend only $30 on a camera that can cover one particular area. You wouldn't need to buy software, hardware, cables, or anything else. Instead, it would connect wirelessly to an app on your phone where you could monitor the feed and take necessary actions at your own discretion.
