随着世界安全形式的变化,社会稳定对公共安全的需求有了更高的要求。在一个大型的视频监控系统中,摄像机数量呈爆炸式增长(每个城市都达到了万个以上规模),电视监控系统要求能够大规模联网,做到视频实时/历史图像网内分发共享,图像资料要求保存的时间越来越长……CCTV从传统以“监视、控制”功能为主的监控系统,快速演变为以“监视、控制、存储、查询、点播/下载”等多业务系统。新业务需求的不断增加,致使传统的监控系统已不能很好的满足用户的需要。IP技术顺应这种发展趋势逐渐成为今后闭路电视监控系统的技术发展方向。
With the changes in the form of security in the world, social stability has higher requirements for public security. In a large video surveillance system, the number of cameras exploded (each city has reached more than 10,000), TV monitoring system requires large-scale networking, so that the video distribution of real-time / historical image network sharing, image The data requirements have been saved for longer and longer ... CCTV has evolved from a traditional monitoring system with the function of “monitoring and control” to “surveillance, control, storage, inquiry, on-demand / download” business system. The increasing demand of new business, resulting in the traditional monitoring system can not well meet the needs of users. IP technology to adapt to this trend has gradually become the future development of closed-circuit television monitoring system technology.
