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 like having ADT. My experiences with them have been mostly positive. When one of my wires was loose, a nice gentleman came by and repaired that. 

He called me ahead of time before he came and cleaned up after himself when he was finished with the job. I would recommend ADT because I’ve had success with it so far."

"I'm 82 years old and when my husband passed away in September, my children told me that they wanted to get me an alarm security for a Christmas present to make them feel more secure that I was alright.

 My house has been broken into three different times where all my guns and antique clocks were stolen. I also work at Walmart from 1:00 to 10:00 at night and my kids said that they didn't want me coming home at night and not feeling like I was secure at the house. 

They got me an alarm system with ADT and when it was installed, the tech was a very nice person. I feel safe and very secure having them, and so far, I'm very well pleased with their service. I also feel that when I come home, pull in the driveway, and into the garage, there would be no one that had broken in to the house and be waiting for me to come home like I hear on the news. I appreciate ADT and I couldn't find a better company. I would highly recommend them to anyone. As a matter of fact, my neighbor over here on the corner stopped by to ask me about my security system and I told her about what my experience with ADT. She said she was going to call them and have them install one for her, and she did."
