The installation of the security system seemed to be all right until I had the first problem. One sensor is too sensitive. Something happened so it didn't clear. The installer said to call them if I had any problems. I called him, he was busy, and he couldn't do it. I called the other people and I haven't heard from a person since. I was satisfied to start with until they said someone would be calling me back and come out and I've never heard anything.
