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

• 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
