Infinova provides cameras and a fiber optic backbone to upgrade the video surveillance system at Shanghai Metro, China\'s largest metro rail system
Solution: Infinova Cameras, Matrix Switches and Fiber Optic transmission

Shanghai Metro, the largest metro subway rail system in China, upgraded its security system utilizing 59 Infinova Networked Matrix Switchers, 70 PTZ dome cameras, over 1400 fixed and fixed minidome cameras, and fiber optic transceivers.

This critical upgrade offered many challenges for the integrators including very large open spaces with multiple entrances and exits, a high volume of rail traffic and large crowds spread throughout many locations on metro lines 1, 2 & 3. The security integrators needed a system that met multiple requirements from the specification including very large scalability, high reliability, precise camera control and a robust architecture.

Shanghai\'s South railway station, serving downtown Shanghai, was one of the largest stations upgraded. It is one of the busiest stations connecting three major areas of the city, the Yangtze River, the Pearl River Delta, and southern cities regions. The South railway station, with the south & north station square, occupies over 60 hectares and during a typical day has large crowds to monitor with high traffic density. The main building consists of a 47 meter high dome with a steel structure that is over 200 meters in diameter. The dome covers about 50,000 m2 and at anytime over 10,000 people can be waiting or moving through the area. Although the South Station was the largest, the security and surveillance system had to cover many other stations spread over long distances throughout the city.
