Secret Service conducts live test of ShotSpotter system at White House

With the president at Camp David for most of the weekend, the United States Secret Service decided that now would be a good time to fire off a few live rounds on the grounds of the White House—so it can evaluate a gunshot-detection technology known as ShotSpotter.

The mounted microphone and computer system is designed to detect gunshots via their audio signature and send prompt alerts to local authorities.
