San Francisco is installing video surveillance hardware and software that can find and track suspected criminals BEFORE they do the crime.

If the system spots a suspect acting strangely behind a fence, in the shadows, or while coming through a door, the software alerts the security personelle to look at that unusual portion of security video.

It’s then the job of the forensic video and audio expert to enhance and analyze the video evidence.
