ARGUS-IS
The ARGUS-IS, or the Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System, is a Defense Advanced Research Projects Agency (DARPA) project contracted to BAE Systems.
ARGUS is an advanced camera system that uses hundreds of cellphone cameras in a mosaic to video and auto-track every moving object within a 36 square mile area.
ARGUS is a form of wide-area persistent surveillance system that allows for one camera to provide such detailed video that users can collect "pattern-of-life" data and track individual people inside the footage anywhere within the field of regard. This is accomplished by utilizing air assets (manned aircraft, drones, blimps, aerostats) to persistently loiter and record video of an area 36 square miles in diameter with enough detail to track individual pedestrians, vehicles or other objects of interest as long as the air asset remains circling above. Automated object-tracking software called Persistics from the Lawrence Livermore labs allows users to auto-track every moving object within the field of regard (36 sq miles) and generate geolocation chronographs of each individual vehicle and pedestrian's movements, making them searchable via geolocation query.
