We have had a Sentry Security home security system for several years. Technical issues are rare, but when they occur, Sentry quickly helps us resolve them. Technical support has always been good, and the technical personnel are always well trained and efficient.

Great service when one of my sensors was malfunctioning. They sent out a service tech the same day.

Sentry Security has provided our home security monitoring for about fifteen years. Prior to that we used another company for nearly forty years, so we have plenty of experience, all good! We asked Peter, the technician who advised us today, for information on upgrading our system because we are replacing our windows. His assessment of our current system and recommendations for changes were thorough and reflected thoughtful, well informed, and appropriate considerations. It is clear that we are still using an excellent security provider!
