DRI Ranges

DRI stands for Detection, Recognition and Identification and is based on the widely used Johnson's criteria.

  • Detection Detect if an object is present
  • Recognition See what type of object it is (i.e. person, vehicle, airplane)
  • Identification For example see if someone is a friend or foe
Detection Recognition Identification
Rabbit 750 meters 187 meters 93 meters
Person 2638 meters 659 meters 329 meters
Vehicle 6388 meters 1597 meters 798 meters

Please note that these values are calculated, always consult the manufacturer for official range numbers.
