Virginia-based Shooter Detection Systems (SDS) has launched an outdoor public security system to detect gunshots in open air environments, such as parking lots, open-air campuses, and public spaces. The technology uses multiple sensor technologies to verify gunshots, minimising false positives.

The SDS Perimeter system utilises a patented multi-factor sensing approach that verifies firearm discharges through both acoustic signatures and infrared muzzle flash. This dual-verification method is designed to deliver alerts within seconds while minimising false alarms in complex outdoor settings. The system incorporates proprietary detection algorithms developed through machine learning to identify gunfire events before they reach populated areas.

“SDS Perimeter reflects how we’ve continued to evolve our technology to help security teams identify and respond to gunfire events before a threat reaches a populated area,” said Rich Onofrio, Chief Technology Officer for Shooter Detection Systems.

The system uses machine learning and proprietary detection algorithms. It verifies firearm discharges through acoustic signatures and infrared muzzle flash. The sensors do not record conversations to maintain privacy. The technology integrates with existing video management and access control platforms. It supports coordinated response across entire properties and campuses.

The technology originated from a development and testing initiative sponsored by the US Department of Homeland Security. The sensors are designed to operate without recording conversations, addressing privacy concerns associated with audio surveillance. The system is compatible with existing video management, access control, and mass notification platforms to support a coordinated emergency response.
