Indexing a video surveillance stream to match an access control credential or token with best facial image detected at a security portal method of operation and system

Abstract

Video still frames with highest facial detection scores are matched and displayed to a security operator console with identity indicia retrieved upon a credential submission event from a physical access control system. An apparatus couples a security operator console to a surveillance camera at a physical access control portal. A video clip containing a frame with highest facial detection score of all frames captured in propinquity to the time of credential submission, is matched to and displayed with the identity indicia. Credentials from a group of people entering together are presented to a security officer console along with video clips simultaneously containing a plurality of faces or perspectives which may be accepted en masse or in part. Time shifting still frames to reconcile with credential submission time stamps concentrates content in a display console. The apparatus retrieves and presents identity indicia in conjunction with a face in the selected frame.
