They tell you you need things that you don’t. Example, told me I needed a different motion detector since I have dogs. He said the detector works if the dogs are under 100 lbs each and won’t go off if it detects the dogs. So since one dog was 50 and one 75 and he said that the system could be armed in away mode with the special motion sensor I bellieved him. After he left(2 smoke sensors, one motion sensor, and a cell phone conversion box, $ 800.00 ! And there already was a wired system installed.) I read that the TOTAL weight of the dogs has to be under 100 lbs. so he charged me $ 135.00 for nothing. I called five times and left messages to ask that the needless charges be credited to my account and got no return call. I accidentally opened a door and set the alarm off 3 times in the first few weeks and received no calls whatsoever. I don’t even believe that it is monitored! I think they are a big rip off with incredibly poor customer service. They get as much from you as they can as fast as they can and then you can’t get in touch with them. All the while talking about how great their church is! STAYAWAY from them! Now I have to switch to another company(with integrity) and pay again to have their equipment installed. STAYAWAY from them!
