众所周知,安防视频监控技术的发展变迁经历了三个阶段:模拟化、数字化、网络化。而与之相匹配的监控数据存储也经历了三个阶段:VCR模拟存储、DVR数字数据存储、网络集中存储。近年来,在很多平安城市项目建设中,前端监控更多地采用高清摄像机,并且大规模联网应用,未来建设比例或将更高。如高分辨率1080P(1920×1080)或500万像素(3744×1408)的超高清摄像机,存储的数据量将更大。同时,由于高清视频
As we all know, security video surveillance technology has undergone three stages of development and changes: analog, digital, network. The matching monitoring data storage has also gone through three stages: VCR analog storage, DVR digital data storage, network centralized storage. In recent years, many safe city project construction, front-end monitoring more use of high-definition video cameras, and large-scale networking applications, the proportion of future construction or higher. Such as high-resolution 1080P (1920 × 1080) or 500 megapixel (3744 × 1408) ultra-high-definition camera, the amount of stored data will be greater. At the same time, thanks to HD video
