Faster awareness, faster response

The standard timeline in an active shooter event runs like this: shots are fired, surviving witnesses call 911 if they can, dispatch verifies the call, and officers are deployed. FBI active shooter studies consistently document that these events unfold and typically end within minutes, often within seconds of the first shot. Every second between that first shot and the moment your building begins its response is a second during which people are making decisions without information. SDS collapses that gap, identifying the event in under a second and triggering your configured response automatically before anyone has dialed a phone.

Traditional security infrastructure records and documents incidents but doesn't accelerate the response. A camera feed requires someone to be watching it. A panic button requires someone to reach it. Shooter detection requires nothing from the people in the building at the moment of the event. Each sensor combines a microphone listening for the acoustic blast with an infrared sensor looking for the heat signature of a muzzle flash, and both must trigger simultaneously to generate an alert. That dual-confirmation is what produces the system's greater than 99% accuracy rate and near-elimination of false alarms. Acoustic-only systems are tripped by a car backfire through an open loading dock door, a heavy dropped object, or a slammed dumpster lid. Those sounds have the acoustic profile of a gunshot but no muzzle flash. A camera strobe or heat source has infrared signal but no acoustic event. Only an actual gunshot produces both at once, which is why false alarms with SDS are exceptionally rare. Each sensor covers 2,500 square feet without requiring direct line-of-sight to the event.

For businesses in higher-risk environments, the liability question is increasingly relevant. Property owners and employers have a duty of care obligation to provide a reasonably safe environment, and documented investment in appropriate safety infrastructure matters when incidents are reviewed by insurers, regulators, and in litigation. A business with gunshot detection, automated lockdown procedures, and a documented emergency response plan is in a materially different position than one that relied on witnesses calling 911. This technology complements staff training and emergency procedures, not replaces them. But "we had the technology and the training" is a meaningfully different position than "we had the training."
