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."

Many people believe that their car is the largest single source of air pollution for which they are personally responsible. But in fact, the average home causes the emission of more than twice as much carbon dioxide--the principal greenhouse gas--as the average car. This is because most of the energy consumed in our homes is produced by burning fossil fuels like coal, oil, and natural gas. This pollution is actually a hidden cost for the energy We use, over and above the dizzying $110 billion Americans spend each year on their home energy bills that's nearly $1,300 per house. Much of this energy use is unnecessary because there are a variety of proven, widely available products on the market today (heating, cooling, appliances, windows, lighting, etc.) to drastically reduce your home's energy bills, and accompanying pollution. What's more, many of these products actually improve the comfort and livability of your home.

"Andre was extremely helpful and kind with the install - I was having issues with my power in my rooms, he helped me navigate the issue, replace the needed sockets, and also gave me extra help regarding recommendations for electrical safety. Could not recommend enough, thanks Andre!"

Home Security Systems questions, answered by experts

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. 

Homeowners insurance can be voided in several scenarios. That can include making too many claims in a short period of time, leaving a home vacant for an extended period of time, renting out a home or room illegally, using a home as a business illegally, and any kind of criminal activity connected to the home.

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to. 

Yes, you can install a home security system in an old house. In fact, you can install a security system in any home. Some wiring may need to be added, but most home security systems do not require a lot of additional wiring. Wireless security systems can easily be installed with minimal additional wiring, if any at all. Most wireless security systems can be monitored and controlled from your smartphone, and the cameras and sensors operate on batteries.

Professionals optimize camera placement, integrate recording systems, and ensure tamper-proof security.
