The field of view of a security camera depends on the lens focal length and image sensor size. The longer the focal length, the narrower the field of view. The image sensor size plays a vital role in determining the width of the field of view.
For example, the Zosi C182 surveillance camera with a 1/2.49″ CMOS sensor and 2.8mm focal length offers a 101-degree field of view horizontally, providing a reasonably wide-angle view. However, if you’re looking for super wide-angle cameras, fisheye cameras and PTZ cameras can offer up to 360-degree wide views.
