Field notes
Camera & DORI
Camera coverage you can prove: DORI (IEC 62676-4) pixels-on-target per zone, lens projection, IR reach from datasheets, and shadow-cast fields of view.

Glass Is Not a Wall
To Wi-Fi, glass is nearly transparent. To a camera, it reflects and refracts. Modeling glass as a plain wall gets both the coverage and the camera view wrong.

Fisheye and Panoramic Coverage
A fisheye lens does not see in a straight line, so a triangular coverage wedge lies about it. How to estimate real coverage for 180 and 360 degree cameras.

Night Blindness: IR From the Datasheet
A camera that reads faces at noon can go dark at 2 a.m. Its infrared reach is a datasheet number, not a lux rating — design night coverage before you install.

PPF Is the Floor, Not the Ceiling
A pixels-per-foot number draws a clean wedge on a flat plan. Fisheye lenses, night IR, and shadows from walls and racking are where camera coverage breaks.

What DORI Actually Means for Cameras
DORI (IEC 62676-4) grades camera coverage in pixels per metre: Detect, Observe, Recognize, Identify. What each tier needs, and why one PPF number fails.
Prove your camera coverage, day and night, before you install.
Design on real floor plans, walk it in 3D, and prove the coverage — then hand off to the field. Talk to us about what your team needs.
