"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."
