FOV & PIXEL DENSITY
For Installers & Integrators
FOV.DENSITY
Work out a lens's field of view and check whether the pixel density at your target distance is enough to identify, recognise, or just detect a person — or flip it around and find the focal length you need.
!
Planning estimate only. Sensor physical dimensions are standard published "optical format" values and may vary slightly by exact sensor model. Pixel-density thresholds (Identify / Recognise / Detect) are a commonly used industry guideline, not a specific compliance standard — check your project's actual spec (e.g. AS4806, EN 62676-4, or client requirement) for the number that applies to your job.

02 Reverse: Find Focal Length
Want a specific pixel density at that distance? This works out the focal length (and matching HFOV) you'd need instead.
