数字化网络安防系统在楼宇自控中的设计与实现

传统模拟技术的日趋淘汰和先进数字设备的高成本成了许多领域亟需解决的一大难题。为了充分利用已有的楼宇控制系统中的模拟控制设备，文章介绍了一种基于MPEG-4的数字化网络安防系统应用在楼宇自控（BA）领域中的解决方案，并给出了具体设计实现及其关键技术，实现了低成本、低带宽条件下楼宇的智能化管理，具有较强的实用性和通用性。

Application and Implementation of Digital Network Security-Monitoring System in BA

The trend of fading analog technique and the fact of expensive advanced digital devices constitute an emergent problem to be settled. In order to play a full role of the existent analog monitoring devices, this paper introduces the scheme and implementation of a digital network security-monitoring system based on MPEG-4 in the BA field. This scheme provides an automatic, functional and universal management way within the limited bandwidth for the building at low cost.
