Digital Video Provided Security For Olympics
30 August 2008Security was a high priority at the Olympics, as well as for the mass transportation systems that got thousands of people to and from the Games and related events. Beijing Metro, which operates the subway system in Beijing, deployed video security technology from ‘Nice Systems’ to help enhance security at more than 20 stations of the city’s subway system.
Nice’s real-time distributed digital video system, called NiceVision Net, can spot suspicious packages left behind on crowded subway platforms and automatically alert security personnel. The system is also used to automatically detect unauthorized entry into secured areas of the stations.
The video system includes NiceVision Analytics, which is comprised of video content analytics applications. NiceVision Analytics is integrated with a control center management application, providing real-time recording and review capabilities that can help security personnel make decisions about incidents.
All Beijing Metro stations connected to the security system are monitored from a station monitoring room and from a central command and control center. This gives security personnel the ability to identify risks and quickly take action if necessary.
‘Nice’ video security systems were used to monitor the two tunnels under Beijing’s main Olympic Stadium and the Olympic Swimming Pool.
In the tunnels, the security technology provides a variety of functions, including vehicle detection, to determine whether there are vehicles parked inside the tunnel; intrusion detection, to spot unauthorized entry into secured areas; counterflow, to automatically pinpoint vehicles moving in the wrong direction and immediately alert security officers; and vehicle counting, to estimate the number of vehicles passing through the tunnel at any particular time.
