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 201 meters 50 meters 25 meters
Person 707 meters 176 meters 88 meters
Vehicle 1713 meters 428 meters 214 meters

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