Fastest Gunshot Reporting Product

How it Works

The Guardian Active Shooter System detects gunshots immediately using both audio and infrared sensors, confirmed within one second.
Building occupants, first responders and occupants are notified of the emergency situation and lockdown protocols are initiated within the next 4 seconds. Live surveillance footage following the shots is displayed to ensure an accurate description of the shooters with their locations highlighted on a digital map in real time
Critical information can be relayed to building occupants using digital radios and mass notification systems to ensure control and safety as quickly as possible. Shot location data is used to predetermine appropriate messaging.

Immediate shot detection and alerts to building occupants and first responders

If an active shooter event takes place, it is imperative that the situation is quickly identified and communicated to emergency personnel and building occupants.

Hoosier Security provides gunshot detection systems that process all gunshot data within the sensor, removing the need for human interpretation or intervention and saving time when seconds matter most. When a shot is detected, the active shooter detection system instantly alerts users to the location of shots on a mapping interface and simultaneously sends this information by SMS text message, email and via other third-party alert systems. In an emergency, critical information is immediately relayed to building occupants and emergency personnel so that proper steps can be taken to control the situation as quickly as possible.
