Abstract

Video collected from a video monitored area may be analyzed based on a passback direction of the video monitored area to detect any passback events in the video monitored area.

Claims

32-1. A computer-readable medium as in claim 1, wherein said initiating said action comprises initiating a triggered response for each detected passback event.

34. A computer-readable medium as in claim 33, wherein said triggered response comprises at least one of initiating an alarm, controlling an audible alarm system, controlling a silent alarm system, accessing an alerting device, accessing an alerting system, sending an alert, logging alert data to a database, taking a snapshot of each detected passback event, culling a snapshot of each detected passback event from said video, recording video of each detected passback event, controlling a camera to zoom in on each detected passback event, controlling a camera to track each detected passback event, performing recognition of each detected passback event, closing at least one door, and controlling an access control system to at least one of lock, unlock, open, and close at least one portal.

37. A method to detect passback events comprising:

defining a passback direction for a video monitored area;

accessing video collected from said video monitored area;

analyzing said video collected from said video monitored area to detect any passback events in said video monitored area based on said passback direction; and

initiating an action based on any detected passback events.

38. A system to detect passback events, comprising:

at least one video camera to monitor at least one video monitored area and to obtain video of said video monitored area;

an analysis system coupled to said video camera, said analysis system comprising a computer system and a computer-readable medium, said computer-readable medium comprising software to control said computer system according to a method, said method comprising analyzing said obtained video to detect passback events in said video monitored area based on a passback direction for said video monitored area; and

a user interface coupled to said analysis system.

39. An apparatus to detect passback events adapted to perform operations comprising a method of:

defining a passback direction for a video monitored area;

accessing video collected from said video monitored area;

analyzing said video collected from said video monitored area to detect passback events in said video monitored area based on said passback direction; and

initiating an action based on any detected passback events.

40. The apparatus of claim 39, wherein said apparatus comprises application-specific hardware to emulate a computer and/or software adapted to perform said defining, said accessing, said analyzing, and said initiating.
