When seconds count…

Cornerstone provides around-the-clock alarm monitoring to multi-family, residential and commercial properties including industrial facilities, schools, retail stores, banks and elevators.

Our UL certified Central Monitoring Station uses hard and mobile phone lines, radio channels, computers, software and trained staff to monitor our customers’ fire and security systems and call the appropriate authorities in the event an alarm signal is received.  We monitor systems across the nation and around the world.

UL certified monitoring is the difference between an Investment and a Liability.
