Summary

The purpose of Recommendation ITU-T H.626 is to define a visual surveillance system based on IP networks. The visual surveillance system provides the display and storage of the multimedia (such as video, audio and image) captured by multiple remote cameras over an IP network for multiple users. It also provides other functionalities, such as remote control, alarm and linkage actions, recording and playback.

This Recommendation defines the functional requirements, model, architecture, entities, reference points and service-control flow of the visual surveillance. This document also describes the hierarchy model for deployment, the visual surveillance management system, and the interworking and service convergence between the visual surveillance system and other multimedia systems.
