Video Camera

A professional video camera (often called a "television camera" even though the use has extend) is a high-end tool for video recording electronic moving images (as opposed to a film camera, that records the images on film). Formerly developed for use in television studios, they are now normally used for corporate and educational videos, music videos, direct-to-video movies, etc. Not as much of advanced video cameras used by customers are often referred to as camcorders.

There are two kind of professional video cameras: High end portable, video recording cameras (which are, confusingly, called camcorders too) used for ENG image gaining, and studio cameras which lack the recording capability of a camcorder, and are often fixed on studio pedestals.

Professional video cameras confine and transfer two dimensional images serially, at specified capture rates, usually in the visible range of the electromagnetic spectrum.

Most studio cameras situate on the floor, usually with pneumatic or hydraulic mechanisms to regulate the height, and are usually on wheels. Any video camera when used along with other video cameras in a studio setup is controlled by a device known as camera control unit, to which they are joined via a Triax or Multicore cable.
