We have had good luck with this company. They came and installed our alarm system several years ago and did a nice job. The one time that we had an issue we got an appointment quickly and the issue was resolved in a professional and timely manner by the owner Bob. Would highly recommend.

We had Cayer Security recently installed in our home. We have a big house with places I cannot see. I sleep better knowing we have Cayer Security watching over us.
