Camera Angle of View Calculator for Surveillance Cameras, C mount lens, and M12 Lens. AoV Calculator.

This camera angle of view calculator takes your scene requirements and determines the viewing angle required by your camera.

People frequently use the term angle of view and field of view interchangeably.

Our angle of view calculator assumes that the camera is centered relative to the scene or object. The object is assumed to be flat and normal relative to the camera.

This calculator can also be used to calculate the angular subtense of a region of interest that is centered in the field of view.
