视频监控技术在我国的上世纪80年代就逐渐兴起来,先后出现过多种视频传输方式。历经了模拟视频的同轴传输方式、模拟视频远距离模拟传输方式、模拟视频远距离数字传输方式,到目前普通应用的数字视频传输方式。随着安防技术向网络化方向发展,数字视频与IP网络传输方式想结合。数字化是网络化的前提和必要条件,视频技术从模拟向全数字过渡是必然的发展方向。
Video surveillance technology in our country in the 1980s gradually rise, there have been many kinds of video transmission. After the analog video coaxial transmission mode, analog video remote analog transmission mode, analog video remote digital transmission mode, to the current common application of digital video transmission. With the security technology to the network direction, digital video and IP network transmission want to combine. Digitalization is the prerequisite and necessary condition of network. The transition of video technology from analog to full digital is the inevitable development direction.
