The ShotSpotter system is an interesting new technology that police have been using in various cities across the U.S and in a couple places internationally. They’re more commonly used in cities with high gun crime.
ShotSpotter listening devices are placed on top of buildings throughout the city where they listen for gunshots within their radius. When gunfire is identified, the police station is notified of where it occured and can help the police respond to the scene much more quickly.
If you watch the video below, you’ll see how the system works. I wish we had this in Denver.
