CA 2296784

An exit guard system automatically detects movement of a subject along an exit path in an unauthorized direction. A first video camera is positioned for video imaging movement of a subject along the path, while a second video camera images the subject for identification. Multiple video motion detectors operate in conjunction with the first video camera to determine direction of movement of a subject along the path. A CPU operates with the video motion detectors under an exit guard program to provide a watching mode, during which frames of the second video camera are continuously grabbed and saved. Audible and/or visual alarm signaling devices are operated by the CPU in an alarm mode in response to traffic of a subject in the unauthorized direction. A video monitor displays modes of operation of the system and control devices allow operator selection and control of modes of operation of the system. Remote access to the system for control, monitoring or other purposes is provided by data modem feature. Method of using such system for guarding movement of a subject along the path is disclosed.
