Coverage Area

Coverage Area

For a CCTV camera or IP camera, the angle of coverage is a feature that describes the angle range that a CCTV camera lens can image. In this, the video image circle is produced by the lens which is big enough to cover the CCTV camera image sensor completely. It is also possible to include some vignetting towards the edge.

If the angle of coverage of the lens does not completely fill the image sensor then the effective angle of view will be limited to the angle of coverage. For IP cameras and CCTV cameras, the angle of coverage is determined by the size of the image sensor and focal length of the size.
