Abstract

A video monitoring system for a plurality of sites. A site security system is located at each site and includes one or more video cameras each outputting a video signal and a processor configured to receive a video signal from each camera, detect predetermined events based on the video signal, generate a video alarm signal upon the detection of an event, transmit the video alarm signal to a central station, and establish a video signal link either with the central station or one of a plurality of satellite stations according to a predetermined protocol upon the transmission of a video alarm signal. A central station includes a router for routing any received video signal to one or more workstations and for routing the video alarm signal to a server configured to associate the video alarm signal with a particular satellite station and to forward the video alarm signal to that satellite station. The satellite station includes a workstation configured to receive the video alarm signal from the central station and to receive the video signal from the site security system.
