GUNSHOT DETECTIONEnhanced Community Safety by Reimagining Gunshot Detection

Published 2 May 2023

A new gunshot detection system delivers new capabilities that significantly improve the response and management of outdoor shootings. The portable system employs two methods of detection for increased accuracy and reduced false positives.

New and improved gunshot detection technology will soon make American communities of all sizes safer. The Science and Technology Directorate (S&T) and its industry partner Shooter Detection Systems (SDS) developed SDS Outdoor, a gunshot detection system that builds on existing SDS technology to deliver new capabilities that significantly improve the response and management of outdoor shootings.

Among these new capabilities are portability and ease of system set up at any location, two-source detection—sound and flash—to confirm a gunshot, real-time alerts that provide near-instant situational awareness to law enforcement and emergency medical responders, and enhanced data recording that aids apprehension and conviction of alleged shooters.

Portability allows the system to be set up practically anywhere, including near outdoor events, and a single person can install it. Additionally, the enhanced system tells law enforcement when and where a gunshot originates, cutting response times dramatically and providing police officers actionable information—for example, data that helps them to determine if there is a single shooter or multiple shooters. Agencies can then use that information to coordinate resource response and counter an active threat.

“It takes about two to three minutes for an individual to call 911 after a gunshot. Gunshot detection technology cuts that time in half and sends a notification to local law enforcement. Police could then dispatch a unit quicker to either stop the incident that’s occurring or to assist in preventing any lives being taken,” said Wilhelm Thomas, officer with the New York Police Department’s (NYPD) Counterterrorism Division. “If we’re there first, we can lock down the scene. This will provide security for the emergency medical services (EMS) and thus help prevent the loss of more lives.”

Although gunshot detection technology is currently in use, it can only be installed at fixed locations. For outdoor public events, portable gunshot detection technology can add another layer of security to already installed security systems like cameras.

“This system does not prevent gunshots. It detects an ongoing shooting to help first responders get there faster,” said Anthony Caracciolo, S&T program manager for First Responder Technology. “The more details officers have about an incident, the quicker they can identify and eliminate the threat, and EMS can tend injured victims safely.”
