摘　　要：介绍了由专用运算放大器制作的有源适配器。利用低成本的五类双绞线作为传输基带视频信号的载体 ,降低了安防监控系统的安装和使用成本 ,同时也便于今后用跳线方法改变与增加监控点。An active adapter made of specific operation amplifier is introduced in this paper. The cheap twisted pair is used as a carrier to transmit the base band video signal, which reduces the installing and using costs of security surveillance system, and is convenient for using the jumper method to change and add surveillance site in future. An example of active adapter used in the security surveillance system is also given.
