DENVER — If you hear gunshots in downtown Denver Wednesday night, it could be because of a test Denver Police is conducting.

The department will conduct live-gunfire tests between 5:30 p.m. and 11:30 p.m. to calibrate the ShotSpotter system, which detects when a gun is fired and where it happens. The system then alerts police so that officers can respond to the area quickly.

The tests will consist of a sequence of gunshots followed by validation of sound detection by the system. No bullets will be fired into the air or ground, and there is no danger to the public, DPD said.

"By quickly notifying police with precise information, the system helps to speed police response, has the potential to save the lives of shooting victims, increases weapons-related arrests, and enhances neighborhood safety," DPD said in a news release. 

ShotSpotter is a system that DPD has been using since early 2015. It captures and triangulates the sound of gunfire and pinpoints the location of where a gun went off to within 25 feet.

The ShotSpotter system expanded to downtown Denver in July, making it the fifth area in the city to be served the technology. The expansion is part of DPD's comprehensive gun violence reduction strategy.

The department said the technology has already been effective in other areas of Denver.
