DORI Distance Calculator

Calculate how far a camera can Detect, Observe, Recognize and Identify, based on resolution, lens and sensor format. Based on the EN 62676-4 pixel density standard.

DORI thresholds per EN 62676-4. Results are theoretical maximums and assume good lighting, focus and a subject facing the camera.
