We had a Protection 1 system put in several years back after someone stole a bunch of patio furniture and may have tried to get into the house. My daughter had not been feeling well that night and she went downstairs to sleep on the couch and she told us she thought she heard someone messing with the door that same night after we discovered the stuff missing. So we wanted to act as fast as possible. We've been pretty happy with the system. Almost no problems at all (a couple minor ones with bad sensors, but they were fixed fast) and it gives us peace of mind. Of course, we also added a 100# GSD, so there's an added layer of alarm there.

We looked at ADT at the time and they were more expensive and we really felt like they were preying on fears a lot more. I don't know if they just high-ball out of the gate as a matter or practice or if they are just that much more. But the Protection1 guy who came out to talk with us was much more down to earth and seemed more interested in getting us a decent deal without playing games right from the start.
