在视频监控的发展过程中,有两个方面的快速发展是大家公认的:一是清晰度,即从以CIF、D1为主的标清时代进入以720P、1080P为主的高清时代之后,摄像机的图像质量得到了很大提升;二是系统规模,基于成熟的以太网技术,大规模数字化视频监控系统的建设变得非常简单,拥有成百上千个前端点位的系统已经是随处可见,甚至拥有上万个前端点位的超大规模监控系统也不再是天方夜谭。而随着视频监控系统前端点位数的增加,在监控室中把所有摄像机的画面解码上墙已经变得不可能,对于安保人员而言,如何在第一时间发现摄像机画面中正在发生的事件成了一件头疼的事。在图
In the process of video surveillance development, there are two aspects of the rapid development is recognized: First, the definition, that is, from the standard definition of CIF, D1 into the 720P, 1080P HD era, the camera Image quality has been greatly improved; the second is the system size, based on sophisticated Ethernet technology, large-scale digital video surveillance system has become very simple to build, with hundreds of front-end point of the system is already everywhere, or even With tens of thousands of front-end super-large-scale monitoring system is no longer a fantasy. With the increase in the number of digits on the front end of the video surveillance system, it has become impossible to decode the picture of all the cameras on the wall in the control room. For security personnel, it is the first time to find out what is happening in the camera’s picture Has become a headache thing. In the graph
