The Sentinel™ gun shot detection technology determines a gunshot in less then 500 ms and reports it to your Security System, Alarm System, VMS and/or Alarm Panel! It operates wirelessly by allowing your security cameras to take a video of a shooter within milliseconds of a gunshot. Our solution also identifies the shooters physical location, can lock or unlock doors, and sends footage directly to first responders within seconds of a bullet being fired from the chamber of any firearm.
