David M.

We had H & R install a complete fire alarm system across our facility. Their Potter-certified technicians knew exactly what we needed and the inspection process has been seamless every year.
Karen T.
Fire Alarm Customer — Commercial Facility
The camera system they put in for our business has been invaluable. Remote viewing from my phone gives me real peace of mind. Great local company that actually picks up the phone.

After a break-in at a neighboring property, we called H & R. They had us set up with a full security system within the week. Fast, professional, and fairly priced.
