Effective Law & Order
Law enforcement officers can use mobile devices to capture face recognition-ready photographs of people they stop on the street; surveillance cameras boast real-time face scanning and identification capabilities; and federal, state, and local law enforcement agencies have access to hundreds of millions of images of faces of law-abiding citizens.

Verification Through Database
Face is auto - matched against blacklist, whitelist or crime database for potential threat identification & prevention action, rather than simply post-mortem.
Frame Slicing
Video feeds are searched and automated alerts are given out if any suspicious behaviour or individual is found.
