网络传输技术——安防信息的高速公路

Network transmission technologies build the highway for security information

随着安防应用的飞速发展,越来越多的网络技术尤其是网络传输技术被大量应用到了城市报警联网、机场周界防范、道路交通监管、特殊场合视频监控等领域,被人们称为"安防信息的高速公路"。目前,网络传输技术的种类繁多,有以太网无源光网络(EPON)技术。

It's well known that the network transmission technology is developing very fast and every year there are new mechanisms of network transmission are being researched and developed.These technologies and products become more and more widely applied in the security system to provide more efficient solutions.For example, the city alarm and surveillance system,the airport perimeter protection and anti-intrusion system,the traffic and transportation security management system and the special site video surveillance system,all these solutions need the up-to-date network transmission technologies.Nowadays the so-called EPON,HFC,XDSL and the wireless transmission are most popular.In this issue we will discuss some focused trends in this field.
