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 529 meters 132 meters 66 meters
Person 1862 meters 465 meters 232 meters
Vehicle 4509 meters 1127 meters 563 meters

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