Background and Importance

• Problems of Existing Video Surveillance System• Huge manipulation cost• Intensive human involvement• Location-restricted

Collaborative and Pervasive

• Our Group• Designed system architecture• Implemented core parts of COPS

Work from Previous FYPs

Ho Chi Wang, Jody

Yiu Ching Chak, Billy

• Not fulfill the requirements for the COPS– Only two components

• Centralized Server

• Simple Client Not effectively use the resources Not achieve a collaborative system

– Not optimized settings

• Not maintainable and flexible for extension– Code-and-Fix strategy– Highly coupled modules

• Lack of project management and documentation

System Architecture – Overview

• Our COPS - Distributed System Architecture was adopted– Real-time Video Streaming Server– Application-Level Multicast Server– Video Storage Server– Web-based Image Server– Dialogic Board Server

– Intelligent Client

System Architecture – Server and Client Structure

• Layered Model – 3 layers was introduced

• A set of well-defined interfaces between modules

• Implemented as Dynamic Link Library (DLL)

• Real-time Streaming Server• Multiple camera supports• Video encoding – H.263+

• 30 fps for QCIF

• 15 fps for CIF

• Video streaming – UDP, RTP and TCP

• Intrusion detection and event-driven alert service

System Functionalities – Streaming Server

• Successful System Re-engineering• A whole system architecture is designed• The system is modulized according to functionalities• Changes to each modules can be isolated• Functions-rich and high performance system is developed

• Good Project Management and Documentations

Conclusion – Major Accomplishments
