An acoustic sniper-detecting system that works well even in complex urban environments is now available. The system, called PinPtr, uses a wireless network of many low-cost sensors to determine both a shooter's location and the bullet's trajectory by measuring both the muzzle and the shock wave. When the system detects an event, it measures the time of arrival and uses a specially tailored data aggregation and routing service to propagate the information through the network to the base station.
