"With crime and break-ins picking up around the city, we felt it was time to invest in home security. Using ADT for the entire process was excellent. They added an extra motion detector to our equipment package for being new customers. We also added the smoke and carbon monoxide detectors. All and all, a great overall security and automation system."

"Amazing system! Did a lot of research on alarm systems....so glad I went with 1st security! They came to my house and explained everything to me, were not pushy at all. Came and installed the system a few days later....took the time to explain everything to me and did an amazing job with the installation. And the price is excellent, both the installation fee and the month to month. So happy with my decision."
