一、全球视频监控设备市场现状在目前的全球监视设备市场中,模拟摄像机仍占据主流,然而监视设备市场正在发生转变。如图1所示,模拟的监控摄像头增长非常缓慢,而高清电视和更高清晰度的监控设备正在快速增长。1.如何实现高清监控?在实际应用中,高清监控的实现主要有两种方式,一种是通过高清视频监控HDcctv,另一种是通过以太网。一般传统的方式是将百万像素摄像机经过压缩的电视信号通过以太网传输 First, the global video surveillance equipment market status In the current global surveillance equipment market, analog cameras still dominate the mainstream, however, surveillance equipment market is changing. As shown in Figure 1, the analog surveillance cameras grew very slowly, while HDTVs and higher definition surveillance devices are growing rapidly. 1.How to realize high-definition monitoring? In practice, there are mainly two ways to realize HD monitoring, one is HDcctv through HD video monitoring and the other is via Ethernet. The traditional way is to pass a megapixel camera compressed television signal over the Ethernet
