I have had a great experience Perimeter Security Systems. We have a retractable gate that kept getting stuck open, and the company had no problems coming by to fix it. They even walked me through the process to see if I was able to master it so it wouldn't be a problem in the future. The staff is more than friendly and I appreciate their hard work and willingness to come out to do the work. I'd definitely recommend their services to other people in the future!
