Image clarity is simulated, not a guarantee of readable faces or number plates. Lighting, camera optics, movement and compression affect actual detail.

DORI Distance Analysis

Indicative maximum distances using traditional detection, observation, recognition and identification pixel-density thresholds.

Detection 38.6 m
Observation 15.4 m
Recognition 7.7 m
Identification 3.9 m

*Coverage height uses a nominal 16:9 active image, and width × height represents approximate scene-plane coverage at the selected target distance — not the ground footprint. Camera installation height is an informational input only. Nominal sensor widths and optical projections vary by camera. Clarity illustration is simulated; results depend on lens, lighting, compression and installation. DORI uses traditional 25/62.5/125/250 px/m thresholds.
