The Defense Advanced Research Projects Agency (DARPA) has selected three companies to work on a research program that could dramatically lower the amount of bandwidth used by networks of cameras. The program, which is called Fast Event-based Neuromorphic Camera and Electronics (FENCE), aims to develop cameras that sense motion, but which are able also to determine what motion is important and represents a threat. According to the agency, the new technology could reduce latency and the usage of network capacity by transmitting only necessary information. Raytheon, BAE Systems and Northrup Grumman are the three defense contractors that have been chosen to work on the research project. Neuromorphic computer systems refers to silicon circuits that mimic brains.
