10.2.2 Distributed Platform

A distributed intelligent video system uses intelligent network cameras to analyze video content in real time so as to
enable prompt response. The architecture can be easily expanded by adding new cameras.

Video/Audio Compression
Compared with centralized architecture, a distributed intelligent video system provides benefits in deployment
costs, bandwidth requirements and content accuracy (Table 10.1).
