Burglary Monitoring

Our home alarm security systems are constantly monitoring to ensure that once a burglary alarm is received at a Customer Monitoring Center, a trained ADT professional will notify you and first responders quickly.

Security Camera Systems

With an ADT wireless home security camera system, you can do more than monitor your home security remotely — you can manage your life. For example, looking in on the cable repairman from your office.

Fire and Smoke Monitoring

When a fire and smoke detector in one of our home security systems is received, a trained ADT professional will notify you and your local fire department as quickly as possible.

Medical Alert Monitoring

Never feel alone again with ADT medical alert monitoring in our home alarm security systems. Push a button to be connected to a trained ADT professional through the two-way voice intercom system. If assistance is needed, this professional will contact the appropriate emergency response services.

Carbon Monoxide Monitoring

A carbon monoxide (CO) leak can spell serious harm for you and your family since it can be impossible to detect without a warning device. Make your home a safer place with CO monitoring services available with most ADT home security systems.

"I've had ADT for a long time even before I moved to this area. I had ADT when I lived in Virginia and in Illinois. By the time I got ready to move into a new development, there had already been break-ins. And so, we contacted ADT 

to get set-up when we had the house built. Right now, I have door and window contacts, motion sensors, and cameras.

All of the interactions that I've had with the sales personnel at ADT had been pretty good. After I had ADT for a number of years, I was considering going to somebody else because of the price. But when I called them and talked to them about it, they actually gave me a better deal and lowered the price on the package that I had. Also, when the installers came out, I had a great interaction with them. They were knowledgeable, very professional, courteous and efficient. And when I got the upgrade, they made sure that they did a neat job. Overall, they did an outstanding job and conduct. I'd recommend them to anybody."

"Using ADT has been easy and it's not complicated at all. I haven’t had many problems except for the app, which I have so my two brothers and I can turn the device on and off. 

I check on my mom when I’m not here and she’s here alone, and one of my brothers is having problems installing the app. It’s downloaded on his phone but it won’t accept his password, which is very frustrating. But I’ve been a long time user and I'm satisfied. If I would move, I would take it with me or have one installed at a new house."
