“This is yet another Infinova installation at a prominent public facility,” reports Mark S. Wilson, Infinova vice president, marketing. “From the Asian Games in Guangzhou to the Ertan Dam, Infinova is helping protect people and property.”

At the Worldexpo Culture Center, Infinova security cameras are installed at entrances and exits, garages, fire control passages, stairways, control rooms, elevators, elevator halls and other important areas. Infinova V1025 fixed colour cameras and V5411 minidome security cameras are installed at indoor passages and halls. Areas with lighting fluctuations, such as the entrance and exit are installed with Infinova V1033 WDR day/night security cameras. Infinova V1728 and V1748 speed dome cameras are also installed at other important areas. All security cameras are configured with auto iris lenses. Wide Dynamic Range (WDR) cameras also are used where needed. Video signals are managed at the control centre, 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 security cameras to the control centre is far longer than standard coaxial cable can effectively handle. For transmission beyond 500 metres, Infinova N3759 fibre optic modems are deployed with signals from the security cameras being transmitted to the control room via fibre.

The control centre features an Infinova V2060 large-scale matrix switcher which supports up to 4096 x 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 security cameras deployed, it is impossible to display real-time video images for all cameras simultaneously in the control centre. Instead, when an alarm occurs, an alarm handling routine is triggered and the matrix switcher calls the live video from the security 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.
