The Denver Police Department will work on its gunshot detection system Thursday evening, meaning people in northwest Denver and downtown might hear a series of cracks from the controlled fire.
Police are expanding the ShotSpotter technology into downtown for the first time, but first have to test it. Officers will also calibrate the existing system in northwest neighborhoods.
The gunshots will sound between about 6 p.m. and 11 p.m. Thursday, according to DPD.
ShotSpotter uses a network of acoustic sensors to detect when and where a gun is fired, alerting 911 dispatchers in less than a minute. DPD says the tech speeds up police response, helps save the lives of shooting victims and aids investigations.
DPD has sensors in Lowry, Montclair, East Colfax and South Park Hill as well.
