作为最近几年崛起的新产品，网络视频服务器已经成为第三代全数字化视频监控系统的核心产品并日益被工程商和用户所熟知。但是，在基于宽带ADSL网络的应用中，如何低成本地实现在动态IP地址环境下监控中心对监控前端的实时访问，仍是困扰诸多工程商和系统集成商的难题之一。本文将就此问题提出完整的解决方案-The rise in recent years as new products, network video server has become the third-generation all-digital video surveillance system, the core of products and projects are increasingly well-known manufacturers and users. However, in the ADSL-based broadband network applications, how to realize low cost in a dynamic IP address environment surveillance center to monitor real-time access to the front end is still a lot of engineering problems and systems integrator, one of the problems. In this paper, this issue will be a complete solution
