A video security system for the remote verification and monitoring of conditions surrounding an alarm signal. A security gateway at the monitored premises detects alarm conditions and transmits information and video relating to the alarm condition to personnel at a central monitoring station in substantially real time for verification. Various embodiments of the system transmit alarm information to the central monitoring station through hybrid-fiber coaxial, DSL, fiber-optic, high-speed fixed wireless and mobile communications networks. The security system may include secondary alarm notification from the security gateway to the central monitoring station via a second network, such as IP, Ethernet, Internet, frame relay, public switched telephone, wireless, and mobile communications networks.
