It's probably not a shock to anyone, but the Department of Defense is funding a program to build Distributed Intelligent Video Arrays (DIVAs) to watch people and alert the authorities if they think that something is amiss.

The article from Wired continues on to describe the background of the Computer Vision and Robotics Research Lab at the UCSD and their ongoing project to build intelligent camera networks.

In the past, these cameras have been used to monitor traffic and provide additional security at the Superbowl.
