Note: The table is only for reference and the performance may vary according to different environment. Note: The optimal detection, recognition, and identification distances are calculated according to Johnson’s Criteria. Detection Range: In order to distinguish an object from the background, the object must be covered by 1.5 or more pixels. Recognition Range: In order to classify the object (animal, human, vehicle, etc.), the object must be covered by 6 or more pixels. Identification Range: In order to identify the object and describe it in details, the object must be covered by 12 or more pixels. | ||||
