This is a IR cut 2.5mm 0.8MP M12 with 1/3" COMOS sensor board lens for CCTV cameras. The IR cut lens is used during daylight to filter IR light so that it does not distort the colours of images as the human eye sees them.It can be used to provide an extremely wide field of view. However, the picture will have an "artificially" wide field of view with a fairly severe curvarture of the video image. Unfortunately, there is no way to provide such a wide viewing angle without this type of distortion. This is a fixed lens with one specific field of view. There is no way to adjust the lens focal length for a dynamic viewing angle.
