"I had issues with a den sensor. The first tech replaced the sensor but I was still having issues. When the second tech came out to install my cameras he replaced the main keypad which solved the sensor issue. 

I felt at ease that he took my concerns seriously and problem solved without having to call and ask for advice or permission."

"I don't know where to begin. My daughter in Murfreesboro, TN needed to upgrade the security system in her home. When she moved in, the security company told her that it was not possible to install an alarm horn or outdoor cameras. 

The eaves of her house are very high and the attic did not permit ready access to placement positions. Robert ** from ADT Security Services in Nashville worked for 6 hours one day and recruited Perry ** to help. Both of these installation technicians returned and worked another 6 hours!!! They came up with an solution that really demonstrated their skill, product knowledge, determination to deliver excellent service. These men accomplished what others had failed. They were friendly and maintained their sense of humor when I accidentally unplugged the camera while they were downloading its online installation. Thanks guys!!! You are wonderful!"

"I remember one cold night a few months back, my garage door would set my alarm off when the wind blew against it. The Attendant answered the alarm so quickly and after I told him that the wind blew against the door apparently because everything else appeared ok. 

The Attendant said, "I will send out a Police just to be sure at 3 am." They came out and looked around my home and one of the policemen told me, "Your Home is the most secured house on this block." I felt real good about that."

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.

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.

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.

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.
