摘　　要：多点位、远距离、强干扰,一直是闭路电视监控系统设计和工程实施中的难题。寻求一种经济、传输质量高、传输距离远的解决方案十分必要。通过对双绞线及其传输系统的实测,分析了双绞线及双绞线传输系统的视频传输特性,并结合对双绞线传输方式经济性的分析,总结出了双绞线传输方式在闭路电视监控系统中的适用场合、优势与发展前景。Multi-spot, long distance and strong disturbance are the problems during the design and construction of the closed circuit television （CCTV） system. It is necessary to find an economical scheme with good transmission quality and long transmission distance. Firstly, the video signal transmission performances of the twisted pair have been measured and analyzed in this paper. Then, the economic advantage of the twisted pair has been analyzed. Finally, summary of the application situation, advantages and prospect of the twisted pair applied in the monitor systems of CCTV are given.
