“With such a significant number of ShotSpotter published gunfire incidents in the past year, it’s clear to see that urban gunfire continues to be a challenge for many communities across the United States,” said ShotSpotter President and CEO Ralph A. Clark.

“But knowledge is power, and we believe the local agencies’ understanding and use of this data is critical in enabling them to partner with communities in reducing gun violence and improving the safety of residents.”

How ShotSpotter Works

ShotSpotter uses sophisticated acoustic sensors to detect, locate and alert law enforcement agencies of illegal gunfire incidents in real time.

The acoustic sensors are strategically placed in an array of 15-20 sensors per square mile in order to reliably detect and accurately triangulate gunshot activity.

Each sensor captures the precise time and location associated with boom and bang sounds (impulsive noise) that may represent a gunshot.

This data is first filtered by machine algorithms that are then further qualified by expertly-trained staff in the 24×7 Incident Review Center (IRC) at ShotSpotter, to ensure the events are in fact gunfire.

This process takes less than 45 seconds, between the actual shooting and the pushed digital alert, which includes a precise location on a map (latitude/longitude) with corresponding meta data such as the address, number of rounds fired, type of gunfire, etc. delivered to any browser-enabled device or mobile device. 

Utilizing the gunfire audio clip, and tactical information, officers can approach the precise location of the gunfire incident quickly and safely to engage the shooter, interview witnesses, and collect key evidence at the crime scene.
