Before arriving on the scene, the tech tells police the exact location of the shooter or shooters, the type of weapon, and number of shots fired. The ShotSpotter tech uses a similar acoustic approach, but in a system designed to protect civilian neighborhoods. Since the tech has been introduced, there have been a number of times that the tech detected a gunfire incident before a 911 call was made for help. This sort of tech can save lives of victims and potential future victims by accelerating the speed of first responders. While proponents say that tech like ShotSpotter can reduce gun violence, critics cite concerns like privacy.
