PTZ cameras can cover a very large area. Not only can they tilt up and down, they can usually rotate 360 degrees. Users can aim a live PTZ camera to any region at any time. This obviously does not work with recorded video or images; the camera does not record its entire 360-degree view. When used for surveillance, PTZ cameras are usually programmed to scan across a set area. This is called a 'guard tour'.
A fixed camera (with or without ePTZ) will usually have between 60-90 degrees of horizontal field-of-view. However, some fixed cameras have exchangeable lenses. This opens up possibilities for wide-angle or telephoto lenses.
