Abstract
An apparatus includes an interface and a processor. The interface may be configured to receive pixel data corresponding to an entrance of a secured area. The processor may be configured to process the pixel data arranged as video frames, perform computer vision operations to detect objects, extract characteristics about the objects, determine a number of people in the video frames, receive an authorization signal from an access control device and generate a control signal. The authorization signal may be used by the access control device to grant access to the secured area. The number of people in the video frames may be determined after the authorization signal is received. The control signal may be generated when the number of people is greater than a number of entrants permitted by the authorization signal. The control signal may provide an indication of unauthorized access to the secured area.
