The Shanghai WorldExpo Culture Center, shaped like a flying saucer (the “spaceship”) and one of Shanghai’s new iconic buildings, is using Infinova cameras, modems and matrix switcher to provide security for the multiple six-story facilities that make up the complex, including an 18,000-seat theater.
The Shanghai WorldExpo Culture Center, shaped like a flying saucer (the “spaceship”) and one of Shanghai's new iconic buildings, is using Infinova cameras, modems and matrix switcher to provide security for the multiple six-story facilities that make up the complex, including an 18,000-seat theater.
“This is yet another Infinova installation at a prominent public facility,” said Mark Wilson, Marketing VP, Infinova. “From the Asian Games in Guangzhou to the Ertan Dam, Infinova is helping protect people and property.”
At the WorldExpo Culture Center, Infinova cameras are installed at entrances and exits, garages, fire control passages, stairways, control rooms, elevators, elevator halls and other important areas. Infinova fixed color cameras and minidome cameras are installed at indoor passages and halls. Areas with lighting fluctuations, such as the entrance and exit are installed with Infinova WDR day/night cameras. Infinova speed dome cameras are also installed at other important areas. All cameras are configured with auto iris lenses. WDR cameras also are used where needed. Video signals are managed at the control center, providing forensic image information for evidence recording and transmission. The system will automatically and dynamically adjust camera angles and select the most effective view and display.
Since the WorldExpo Culture Center site is expansive, distances between some cameras to the control center is far longer than standard coaxial cable can effectively handle. For transmission beyond 500 meters, Infinova fiber optic modems are deployed with signals from the cameras being transmitted to the control room via fiber.
The control center features an Infinova large-scale matrix switcher which supports up to 4,096 by 512 channels. WorldExpo Culture Center security personnel can predefine tours, time events and set alarm displays. Guards can view all parts of the center from the control room and respond quickly in case of an event.
With so many cameras deployed, it is impossible to display real-time video images for all cameras simultaneously in the control center. Instead, when an alarm occurs, an alarm handling routine is triggered and the matrix switcher calls the live video from the camera that triggered the incident and displays this on the monitor. Using this solution the video surveillance system can manage alarms from multiple inputs including the burglar alarm, access control and parking lot management systems.
