近年来,视频监控的网络化发展日益普及,而网络监控是以网络为基础的,各行业应用的安防监控的网络化规划与建设越来越重要。在安防系统中,网络视频信号与日常的数据有比较大的差异,它具有不间断、连续性、大数据包传输的特性,一旦出现网络故障,会导致视频中断、丢失的现象,直接会影响日常监视和录像取证,此时发生异常情况,损失可能是无法估量的。因此,在条件许可的情况下,视频专网的建设非常必要,它保证了系统的稳定性、安全性,同时也是网
In recent years, the network development of video surveillance has become more and more popular. Network monitoring is based on the network. It is more and more important that the network planning and construction of security monitoring in various industries are used. In the security system, the network video signal and the daily data are quite different, it has a continuous, continuous, large packet transmission characteristics, in the event of network failure, will result in video interruption, loss of the phenomenon will directly affect Daily surveillance and video forensics, abnormal circumstances occur at this time, the loss may be immeasurable. Therefore, under the conditions permitting, the construction of video private network is very necessary, which guarantees the stability and security of the system, but also the network
