CCTV cameras / Axis
How wide the AXIS P3268-LV sees, its pixel density at distance, and how far out it can detect, observe, recognise and identify a person, at both ends of its lens range.

Distances are measured straight out along the centre of the view, with the camera level. A real camera is mounted high and tilted down, and its pixel density falls off towards the edges of the picture, so the useful range on the ground is usually shorter. Lighting, compression and lens distortion also cut real-world detail.
Plot-LV FOV allows for mounting height, tilt and walls, and shows the real coverage on your own floor plan. What DORI and px/m mean.
Drop in your floor plan, place the camera and check coverage room by room. Free, no sign-up.
