Professional camcorders

A professional video camera (often called a television camera even though the use has spread beyond television) is a high-end device for creating electronic moving images (as opposed to a movie camera, that records the images on film). Originally developed for use in television studios, they are now commonly used for corporate and educational videos, music videos, and direct-to-video movies.

There are two types of professional video cameras: High end portable, recording cameras (essentially, high-end tapeless camcorders) used for Electronic news gathering (ENG) and Electronic field production (EFP) image acquisition, and television studio cameras which lack the recording capability of a camcorder, and are often fixed on studio pedestals. Portable professional cameras are generally much larger than consumer cameras and are designed to be carried on the shoulder.Professional television camera history has two main lines: the gradual shrinking of the camera as it became more versatile and self-contained; and a progression of sensors from large insensitive video camera tubes to smaller, much more sensitive tubes and finally to very small, very sensitive solid state charge-coupled device (CCD) and active pixel sensor (CMOS) imagers. Betacam cameras that contained their own recording mechanisms did not appear until the early 1980s.
