随着高速公路日趋成网,路网内视频监控系统联网势在必行,数字视频监控系统的广泛应用,高清视频监控在高速公路建设中的蓬勃发展,均对视频监控存储提出了新的要求。回顾了视频监控存储的不同阶段:模拟化阶段-VCR(模拟磁带录像机)、数字化阶段-DVR(数字硬盘录像机)、网络化阶段-网络存储技术(直连存储、附网存储、存储局域网)。最后提出目前最适合高速公路视频监控系统存储的技术及方式。
As the expressway becomes more and more networked, networking of video surveillance system in road network is imperative. The wide application of digital video surveillance system and the vigorous development of high-definition video surveillance in highway construction all put forward new requirements for video surveillance storage . The different stages of video surveillance storage are reviewed: VCR (Analog Video Recorder), Digital Phase-DVR (Digital Video Recorder), Networked Phase - Network Storage Technology (Direct Connect Storage, Network Attached Storage, Storage Area Network). At last, it puts forward the most suitable technology and method of video surveillance system for highway storage.
