DORI and Pixel-Density Analysis

Understand coverage quality by observation task

Visualize Detection, Observation, Recognition, and Identification zones across the design.

Benefit

Make coverage decisions based on pixel density and standard CCTV observation criteria.

How it works

The platform calculates pixels per meter at distance and displays color-coded DORI zones. Hover or select a zone to see the value, intended use, and the camera parameters driving it.

Typical user

Security consultants, enterprise reviewers, and integrators validating coverage requirements.

Example use case

A corridor camera is reviewed to confirm that the Identification zone reaches the door positions while the Detection zone covers the full corridor length.

Key inputs

  • Camera resolution, sensor, and lens
  • Mounting height and tilt
  • DORI threshold settings

Key outputs

  • Color-coded DORI zones
  • Pixels-per-meter readouts
  • Coverage suitability by task

Technical note

DORI thresholds are planning aids. Actual performance depends on lighting, compression, scene content, and manufacturer implementation.
