Cambridge Police are alerting residents that the department will be using gunfire sounds to test the city's ShotSpotter system Tuesday night.

Police said the department will conduct "live-fire gunshot training" on Tuesday between 8 p.m. and 9:30 p.m. in the Area 4 and Inman neighborhoods.

"The controlled testing is being conducted for sensor calibrations, quality of gunshot detection and validation of analysis purposes," police said. "The training exercise presents no danger to the public and we urge residents not to be alarmed."


The tests will consist of a sequence of gunshot sounds. Testing areas will be held in cordoned-off areas away from the public.

ShotSpotter, which is also used in Boston, detects the sound of the gunfire explosion as it radiates out from the point of origin and helps officers quickly locate the exact spot a gun was fired, police said.
