Abstract
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 stroring 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. 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.
