Hong Kong Area Traffic Control

Video surveillance for Hong Kong Island traffic.
UniVision was awarded contract TD86/2003 to provide the Hong Kong area a traffic control CCTV system for monitoring the Hong Kong Island traffic. This was the first large scale CCTV system using digital compression and transmissions. There are a total of six control centres including the main control centre in Habour Building Central, traffic control centre in Immigration Tower, regional command control centre of the Hong Kong police force in North Point, the regional office of the highway department in North Point, the regional office of the traffic engineer division in Immigration Tower and the traffic control division in the Habour Building.

Teleste MPEG-4 video encoders and decoders are used for digital video compression and transmission. An Ethernet network is provided for the HKATC CCTV system. The network will link up all the associated equipment of outstation, instation and HBCC central equipment. All the video streaming, camera control data, and equipment status information are transmitted through the network.
Customer need
