This technology triangulates where a shooting occurred and alerts police officers to the scene, letting them know relevant information: including the number of shots fired, if the shooter was moving at the time of the incident (e.g., in a vehicle), and the direction of the shooter's movement. ShotSpotter enables a much faster response to the incident and the ability to assist victims, gather evidence, solve crimes, and apprehend suspects more quickly.
