Free CCTV camera FOV calculator
Drop any camera on a satellite map and instantly see its field-of-view cone. Adjust focal length, sensor size, mount height and rotation — coverage updates in real time.
Try it: FOV & DORI calculator
DORI per EN 62676-4: detect 25 px/m, observe 63, recognize 125, identify 250.
Why visual FOV beats spec sheets
A 90° camera at 4 m looks great in the brochure and useless when an obstacle blocks the line of sight at 6 m. SightPlanr renders coverage on the actual satellite image of your site so you see the real picture before you buy.
DORI distances built in
Every camera shows Detect / Observe / Recognize / Identify ranges per the EN 62676-4 standard, so you know whether a face will be identifiable at the gate.
Bullet, dome, PTZ, fisheye
Switch lens types and watch the cone change. Fisheye renders as a 360° circle; PTZ as a rotatable beam. All coverage respects obstacles you draw on the map.
