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 108 meters 27 meters 13 meters
Person 380 meters 95 meters 47 meters
Vehicle 920 meters 230 meters 115 meters

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