CCTV Monitors


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 manufacturer's camera or cable.

The monitors in NTSC system have 525 vertical scanning lines regardless of their size. The horizontal 700 TV lines of B/W monitors represents medium level and more than 900 TV lines means high resolution in EIA system. The color monitor's horizontal resolution of 300 TV lines means medium quality and that of more than 450 TV lines means high resolution.

To maximize the system's resolution, it is recommended to choose a monitor which has better resolution than that of the camera.
