US Patent 7504942 Local verification systems and methods for security monitoring

A security monitoring system for reducing the number of false alarms through verification comprises a remote system at a first location remote from a second location and a local system located at the second location. The remote system comprises a remote database. The local system is electronically linked with the remote system to provide indication of alarm events to the remote system and comprises at least one camera operable to capture at least one image of a local object in view of the camera, a local database operable to electronically store at least one template corresponding to an authorized object, and an image processing system operable to perform a visual verification. The visual verification comprises comparing the at least one image of the local object with the at least one template corresponding to the authorized object and, if a matching result occurs from the visual verification, suppressing indication of an alarm event to the remote system.
