在视频监控系统中,监控图像的传输是整个系统的一个至关重要的环节,选择何种介质和设备传送图像和其它控制信号将直接关系到监控系统的质量和可靠性,传输部分是整个监控系统的中枢神经,传输网络的设计和选择决定了监控系统的可靠性和可扩展性。视频监控技术在我国的上世纪80年代开始逐渐兴起,基于传输介质的不同先后出现了在同轴电缆传输介质下的短距离传输方式,光纤介质下的模拟视频远距离模拟方式传输、模拟视频远距离数字方式传输和光平台传输方式。
In the video surveillance system, the monitoring image transmission is a crucial part of the whole system. Choosing which medium and equipment to transmit images and other control signals will directly affect the quality and reliability of the monitoring system. The transmission part is the whole monitoring System of the central nervous system, transmission network design and choice of monitoring system reliability and scalability. Video surveillance technology in our country started in the 1980s began to gradually rise, based on the different transmission media has appeared in the coaxial cable transmission medium short-distance transmission mode, the optical media analog video remote analog mode transmission, analog video Distance from the digital transmission and optical platform transmission.
