Gunshot detection technology is a vital advancement in enhancing building security against active shooter threats. Utilizing acoustic sensors and intelligent analytics, these systems detect gunfire, determine its precise location, and immediately notify 911 dispatchers, significantly improving emergency response times. Many systems also integrate with building security controls to trigger automatic lockdowns, securing doors and restricting access to limit the shooter's movement. By delivering real-time information and enabling rapid defensive actions, gunshot detection technology greatly strengthens a facility’s ability to protect occupants and mitigate harm during critical incidents.
