Japanese Patent JP4101655

B2

A security monitoring system including; an exit and entrance camera located at the exit and entrance of a structure; a detector for detecting the exit or entry of an individual; an image recording system for storing images from the exit and entrance cameras; and a computer vision system for analyzing the stored images using a predetermined criteria to determine if the exiting and entering individuals are the same. Preferably, the cameras are video cameras and the detector is either a door contact sensor or an infra-red. The system preferably transmits an alarm signal and/or at least a portion of the stored images to a remote site if the exiting and entering individual is determined not to be the same. In a preferred implementation, the system also includes a database for storing face image data for each authorized individual of the structure; and a face recognition system for comparing the stored images from the entry and entrance camera with the stored image data in the database and for determining if the exiting and entering individual is one of the authorized individuals. In this implementation, the alarm signal and/or at least a portion of the stored images is transmitted to a remote site if the exiting and entering individual is or is not determined to be the same and the exiting and entering individual is determined not to be one of the authorized individuals.
