的“work flow” of a 色彩安全系统 begins with, and is really based on, the 数字视频 color 监视器. A 色彩安全系统 may have only one camera, or it can consist of as many as sixteen when the system utilizes one 硬盘录像机. 的camera or cameras send their color video data to the 硬盘录像机 unit which contains an on-board computer processor designed specifically to do work with color video data and coordinate the 色彩安全系统 functions. Once the processor has interpreted the digital data from the camera, it compiles the data into a 数字视频 file which can be viewed live if a monitor accompanies the system and/or saved for later use on the 硬盘录像机 硬盘驱动器.
的digital 11选5遗漏 in a 色彩安全系统 记录数字图像 by converting light energy into electrical energy. It does this using one of two different sensors that create measurable electronic charges when light strikes their photosites. 的sensors are known as 充电耦合设备 or CCDs or Complimentary Metal Oxide Semiconductors or CMOSs.
这些传感器在非常小的面积内具有非常小的二极管。大多数彩色安全系统相机’ sensor chips are less than 1/2 inch square in size. 的lens focuses the light image on this small area, which on a typical 1/2 inch CCD can contain 300,000 to 500,000 photosites. 的sensors’通常将photosite指定为检测红色，绿色或蓝色的光。这种配置通常称为拜耳滤波器。汇总来自所有红色，绿色和蓝色感测二极管或光敏二极管的数据时，将创建高质量的电子彩色图像。
的色彩安全系统 further processes the electronic image by passing it through an on-board circuit chip called an analog-to-digital converter. This converts the electronic analog signals into binary or digital data that is then transmitted in a variety of ways, one of the most common being along an RG-59 哄ial video transmission cable. (Signals can also be sent wirelessly via radio waves).
的other end of the cable is connected to the 硬盘录像机 unit. 的data from the 色彩安全系统 camera is still unrefined and it is the responsibility of the 硬盘录像机 unit with its accompanying 数字信号处理器 or DSP to add the finishing touches. It does this by using a utility, either in software form or contained in an on-board microchip, that reduces the size of the otherwise incredibly large 数字视频 file without sacrificing a significant amount of quality.
Digital video, like cinematography, actually consists of several photographs (digital-based in this case) that are taken in a very short period of time. 的human eye and brain are slow enough to fool into thinking they are seeing fluid, 运动 video if the photographs pass by quick enough. 的number of photographs taken in one second is usually called the “frame rate”并被指定为“frames per second”或fps，通常约为29 fps。
每个颜色安全系统都使用上述实用程序的一种形式。 H.264是最新，最有效的COmpression / DECompression或CODEC实用程序之一。使用编解码器可使文件更易于处理，并增加DVR的最大存储容量。
