EARS Fixed Site Sensor

Gunshot Localization System

The EARS® Fixed Site Sensor (FSS) Node incorporates QinetiQ North America’s EARS Gunshot Localization System sensors into a fixed-site location. The fixed site sensor provides protection by monitoring gunshot movement over a large area. This information is used to locate gunshots, guide an evacuation route, plan an armed response along with other uses.

Gunshots are detected in less than 1/4 of a second and alerts are broadcast on a tactical network of EARS sensors for large area protection.  These sensors are reliable and effective and have been combat-proven to protect Soldiers.  The system features a rugged enclosure with Ethernet connection and Power-over-Ethernet (PoE).
