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 375 meters 93 meters 46 meters
Person 1319 meters 329 meters 164 meters
Vehicle 3194 meters 798 meters 399 meters

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