Protect your passengers with state of the art gunshot detection certified by the U.S. Department of Homeland Security and proven in the transportation environment.

Transportation terminals are intended to be open and accessible environments where thousands of people can be gathered at one time, a fact that unfortunately makes these facilities vulnerable to targeted acts of violence. Our transportation customers know they can trust the Guardian Indoor Active Shooter Detection System to perform in the oftentimes complex terminal environment safely and securely and with 100% accuracy, providing a common operating picture that provides situational awareness when immediate, real-time incident information is needed most.
