December 14, 2004 A microphone surveillance system based on brain cell research is being used to combat shootings on the streets of Chicago and Los Angeles. The SENTRI system developed by Theodore Berger, director of the University Southern California's (USC) Center for Neural Engineering, has been trained to instantly recognise the sound of a gunshot within a two-block radius with high accuracy. SENTRI can then tag where the shot was fired, zoom in and photograph the shooter with it's built in camera and even make a 911 call to the police station. Police can then remotely control the camera to track the offender and dispatch officers to the scene in an integrated human-computer crime response.
