Multi-Camera Tracking Works?

Author: Carlton Purvis, Published on Jun 27, 2013

Being able to track people across cameras and buildings simply by using cameras and analytics is something of a 'holy grail' for the surveillance industry.

Two researchers from Carnegie Mellon University have developed just such a system that allows them use surveillance cameras to track a person's movements throughout a building, even when they are out of sight of the camera. The set-up combines three different datasets that allow them to tag and identify people and place their movements on a map. In this note, we interview one of the researchers and breakdown how the system works.

Very complexed and commercially not ready perhaps ...

These guys - 20220surveillance.com - (whom I've never heard of) claim to have an operational model of multi-camera tracking.
