Abstract
A TV camera wherein both the lens and its control system are completely enclosed in a casing of the camera to protect them from dust, dirt and damage. Massive control knobs are secured on the side wall of the casing for controlling the focus and the zoom. The iris is cable driven by a linear control mounted on the side wall of the casing and the indication of the iris setting is provided on the rear control panel having a viewfinder. A self-balancing cradle mount supports the camera slightly above its center of gravity. Independent pan and tilt friction adjustments can lock the camera in any desired position. A pan and tilt handle is located at the rear of the control panel.
