C-MOS

Complementary Metal -Oxide Semiconductor. A video image sensor chip that produces much lower quality picture than CCD chip.

Camera Sensor

Video image sensor, Video image sensor CCD or C-MOS chip.

CCD or C-MOS chip

<More details>

CCD (charge coupled device) consists of several hundred thousand individual picture elements (pixels) on a tiny 1/2", 1/3", or 1/4" chip. Each pixel responds to light falling on it by storing a tiny charge of electricity. The pixels are arranged on a precise grid, with vertical and horizontal transfer registers carrying the signals to the camera's video processing circuitry. This transfer of signals occurs sixty times per second. The 1/3" CCD chip is the most widely used sensor format these days; its size is 5.5mm (diagonal), 4.4mm (horizontal) and 3.3mm (vertical). The 1/4" sensor format, recently being used in color cameras, is 4mm (diagonal), 3.2mm (horizontal) and 2.4mm (vertical).

CCTV

Closed Circuit Television

It does not broadcast TV signals but transmits them over a closed circuit through electrically conducting cable or wireless transmitter and receiver.

<More details>

CCTV, Closed Circuit Television, is a TV system that does not broadcast TV signals to public but transmits them over to limited monitor(s). CCTV system usually utilizes CCD video cameras (to produce the video), cable or wireless transmitters / receivers or Internet (to transmit the video), and monitors (to see the video). CCTV system is not only applied to serve the security and surveillance purpose but also to other fields like laboratory in schools or in private companies, even to production lines in factories. As the application of CCTV system increases, the CCTV industry has developed various of CCTV equipment such as time lapse VCRs, combiners, infrared illuminators, pan / tilt, etc. The most recent development is web camera server that uses the Internet for remote surveillance.

Camera

A part of the CCTV system that captures the video pictures.

Monitor

A part of the CCTV system that receives the video pictures from a camera and displays them.

B/W Monitor and Color Monitor

In the past, 9 to 12 inch (diagonal) B/W monitors were widely used in the field. These days, many people are looking for 14 inches for color monitor and 17 inches for B/W. As the color monitor needs 3 different color dots to produce one pixel of information on the monitor, it usually has lower resolution than B/W monitor.

Single Monitor, Quad Monitor and 4-CH. Monitor

Single Monitor is usually professional monitor with one video input of BNC jack. Quad splitter, video switcher or multiplexer can be connected to single monitor to combine multiple cameras. Quad monitor has built-in quad splitter and usually has 4 DIN jacks for video inputs. 4-CH Monitor has built-in 4 channel video switcher and usually has 4 DIN jacks for video inputs. Quad Monitor or 4-CH. Monitor is usually a part of packaged observation system and is not compatible with other Manufacturerr's camera or cable.

CRT

Cathode Ray Tube

The vacuum tube part of a monitor or television.
