Abstract: The Active Shooter Response Capability (ASRC) integrates the ASRC application software, heads-up-display (HUD) smart glasses, ASRC processor/transmitter/controller (PTC) and antennas, with either an existing or ASRC provided CCTV/video surveillance, gunshot detection system (GDS), and loudspeaker (1MC). The PTC provides connectivity for multiple devices to accommodate dedicated processing for multiple response teams. ASRC system enables real-time situation awareness providing first responders the ability to visually locate and track an active shooter while executing a breach entry into the scene. When first responders approach the site of a reported active shooter or gunshot detection system alert of gunshot, the ASRC app is accessed on the squad car onboard computer or optional ASRC tablet which remotely syncs with the facility's PTC. This interaction enables the scroll thru each CCTV/Surveillance camera view to locate and lock-on/auto track the shooters movements.
