Perimeter installed a security system for my home 14 years ago and I've only had ONE problem in that entire time frame. At the time, they were one of the few security system providers in the area. I called around to the others, but Perimeter were the only company to know what they were talking about.
The install was the biggest job they completed and subsequent visits were for maintenance. The signal for the system is in a remote area and rats have a field day, pun intended.
The most recent issue I discovered rodents were chewing on the wires, causing the garage door to open and close on its own. It took a while to get someone on the phone, which was the first time that ever happened. Perimeter contacted me and they were out in no time to fix the issue. Like I said, this is the only issue I've had with them over 14 years.
I could do some of the maintenance myself, but being older means I can't do everything like I used to. I'm happy I can call Perimeter. I know they'll get the problem taken care of. Very polite and knowledgeable people.
