SpotShotter: New Technology Could Help Detect Gunfire

The SpotShotter tool is a gunfire detector gadget. Its wireless sensors pick up the sound of gunshots and differentiate sfrom other loud noises, such as fireworks. When a gun goes off, a sound wave registers on the device, which sends a message within seconds to the police dispatch computers. It can detect gunfire as close as 10 feet away in a two-mile range.

The SpotShotter provides law enforcement officials with an interesting means of forensic evaluation. By affixing acoustic sensors to trees, telephone poles, and other towering structures, the SpotShotter monitors the auditory signature of gunshots. When a shot is fired and detected, the SpotShotter calculates the position from which it was fired, based on acoustic information received by the sensors, then sends the data (via phone lines) to a central server, which law enforcement agents can access for their investigation.

A similar device used in the military is the “Boomerang” microphone, which is mounted to an army vehicle (HMMWV), and is an acoustic system designed to detect the range and elevation of incoming small arms fire. The “Boomerang” system is being developed by the Marine Corps Warfighting Laboratory in Quantico, VA and the Defense Advanced Research Projects Agency (DARPA).
