Purdue University researchers have developed a prototype system that can tap into thousands of cameras located in numerous venues, including parking garages, college campuses, national parks, and highways.

The system is a combination of the existing Visual Analytics Law Enforcement Toolkit (VALET) and Continuous Analysis of Many CAMeras (CAM2) systems. VALET can visualize multiple sets of data, including crime locations, calendar events, and weather, while CAM2 is an interactive visualization and analysis tool that shows the locations and orientations of public network cameras.

The new system integrates public and closed-circuit TV cameras, and quickly finds which area is covered by which camera.

Purdue professor Yung-Hsiang Lu notes many organizations have deployed cameras for a wide range of purposes, and they are accessible to the public without the need for a password. CAM2 locates public-network cameras and identifies certain properties, such as location, orientation, whether it is indoors or outdoors, the frame size, and frame rate.

Information is displayed on a map so law enforcement and the general public can visualize which locations are monitored by the public network cameras.

The system also could be used to quickly find damage, plan rescues, and other operations during natural disasters.
