Highway surveillance solution solves the problems brought by the dispersed front end cameras, centralized management 

and distributed toll station storage. Highway surveillance system has long laying distance,unified laying mode and high 

demand for transmit reliability. Facing those requirements, DSD Technology put up with EPON (Ethernet Passive Optical

Network) and RRPP (Rapid Ring Protection Protocol) to satisfy them. Toll stations are equipped with NVR (Network 

Video Recorder) while highway lanes with High-definition IPC. Through Uniview intelligent photo capture system, vehicles

' high-definition photograph and video, high-definition video storage couldbe integrated together in front of users. 

Moreover, the management platform has the functions of vehicle driving trace analysis and vehicle laws violation intelligent 

analysis. Moreover, by using advanced NGN structure, the malfunction of central management platform would not 

influence the surveillance of subordinate toll stations.
