作为安全防范系统的重要组成部分—视频监控系统,一直以来,备受广大用户和各大厂家的关注。从早期的模拟系统发展到今天的网络视频监控系统,视频监控行业正面临着一次前所未有的变革,呈现出以由“弱电集成商”唱主角向以“IT系统集成商”为主力的趋势。网络设备生产商、网络存储设备生产商、数字化编解码器生产商的介入,促成构成视频监控系统的各组成部分(采集、编码、传输、存储)正在向“智能化、网格化”的方向发展。随着一些新技术、新架构、新产品的大规模使用,视频监控技术发生了“质”的转变,冲突与挑战,风险与机遇,视频监控迎来了新的发展“春天”。传统的视频监控图像存储方式从早期的硬盘录像机的机内硬盘存储到外接磁盘柜存储,直接连接存储(DAS)、网络附加存储(NAS)、存储区域网络(SAN)等名词让人眼花缭乱,各种存储解决之道到底孰优孰劣呢?本文进行逐一分析。
As an important part of the security system - video surveillance system, has always been the majority of users and major manufacturers of concern. From the early simulation system to today’s network video surveillance system, the video surveillance industry is facing an unprecedented change, showing a “lead by the” weak integrator “to” IT system integrator “as the main force trend. The involvement of network equipment manufacturers, network storage equipment manufacturers and digital codec manufacturers has contributed to the ”intelligent, gridded“ implementation of the components that make up the video surveillance system (acquisition, encoding, transmission, storage) The direction of development. With some new technologies, new architectures and large-scale use of new products, video surveillance technology has undergone ”qualitative“ changes, conflicts and challenges, risks and opportunities, and video surveillance has usher in a new development. ”Spring" . Traditional video surveillance image storage methods From the early hard disk recorders in the hard disk storage to external disk storage, direct attached storage (DAS), network attached storage (NAS), storage area network (SAN) and other terms dazzling, each Which kind of storage solution is better? This article analyzes one by one.
