Surveillance Is All About Crunching the Data

Complicated software takes the inputs and "sees" patterns

One of the central elements in last week's Trapwire story involves the application of "behavioral recognition," also known as "video analytics," to camera feeds. What are we to make of this technology?

In essence, video analytics is a form of artificial intelligence that tries to automatically derive meaning from a video feed. Face recognition, license plate recognition, and red light cameras are each examples of the automated extraction of meaning from a video feed, but what I'm focused on here are technologies that aim to offer more general analysis of behaviors that are taking place in a camera's field of view. Examples include the tracking of people throughout an area, zone or perimeter protection, determination of (and detection of deviations from) "normal" patterns of movement in an area, and the detection of abandoned objects.
