Is the system is easily fooled by other loud noises, like cars backfiring and firecrackers?

While the ShotSpotter system detects many loud, impulsive sounds, we use sophisticated technology and well-known science to filter out sounds that are not likely to be gunfire. Those non-gunfire sounds are not published to customers as gunfire. ShotSpotter technology has a 97% accuracy rate for detections across all police department customers nationwide for the last 4 years. This statistic has been independently verified by data analytics firm Edgeworth Analytics.

This is why over 180 cities rely on the ShotSpotter technology to detect and alert law enforcement to instances of gunfire. With patented technology and highly trained human reviewers who can replay the sound, look at the direction of sensor participation, and analyze the audio waveform, the ShotSpotter system is highly accurate at distinguishing gunfire from other bangs, booms, and pops.
