More about this technology

Gunshot detection is a technology law enforcement uses to receive alerts on where gunfire may occur in neighborhoods. This technology relies on a series of acoustic sensors mounted on street lights or on the sides of buildings. When a loud noise triggers the sensors, software triangulates the estimated location of the gunfire.
