They also say a lot of analysis can be made based on data collected from even sparsely placed microphones, and give an example:
ShotSpotter sensors detect gunfire at a range of one to two miles away from the sensors, and ShotSpotter systems have been shown to be accurate to within 25 meters over one to two mile ranges.
In addition, ShotSpotter performs real-time spooling of all signals captured at a sensor, to support later detailed forensic and intelligence analysis of events. Such information can include other non-weapons events, weapon type and direction of fire analysis, and even information related to the direction and speed of shooters on the move.
