Shooter Detection Systems is committed to protecting our communities with the Guardian Indoor Active Shooter Detection System. Guardian was built from gunshot detection technology credited with saving over 250 lives in military conflicts across the globe. Guardian is a system of smart sensors in wireless or Power-over-Ethernet (PoE) options that detect gunfire in buildings and report that a shot has occurred within one second and with ZERO FALSE ALERTS. Protecting sites across the nation today, Guardian immediately and accurately detects gunshots and communicates incident details to those exposed to the threat in real-time. This plug-and-play system is designed to work independently or integrate with existing technologies to provide security officers, local law enforcement, and occupants with immediate, actionable information to help make the best decisions to respond when seconds matter most.
