Camera field of view is the range of images that the camera can capture. It can be used to describe the area or scene range that the camera can cover.
The size of the camera’s field of view depends on multiple factors, including the focal length of the camera, the size of the image sensor, and the installation position and angle. In general, smaller focal lengths and smaller image sensors result in a larger field of view.
The field of view is often described as a horizontal, vertical, or diagonal angle. For example, a camera may have a 100-degree horizontal and 60-degree vertical view, meaning it is able to see objects within 100 degrees in the horizontal direction and 60 degrees in the vertical direction.
Understanding the camera field of view is important to select the appropriate installation location and to determine whether the desired scene can be fully captured.
