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 525 meters 131 meters 65 meters
Person 1847 meters 461 meters 230 meters
Vehicle 4472 meters 1118 meters 559 meters

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