The current analogue system has been expanded with the addition of 48 cameras using IndigoVision’s IP video system, creating a fully integrated 250 camera hybrid solution. The aim is to provide a platform for full migration to IP video in the future.
The migration project was designed and installed by Tung Po (HK) Technology Enterprise Ltd. Tung Po also developed bespoke software to create an integrated ‘front end’ for both the existing analogue system and IndigoVision’s IP video.
This was interfaced with ‘Control Center’, IndigoVision’s IP video and alarm management software.
Like many large analogue systems, Hong Kong’s CCTV surveillance consists of a number of isolated video control rooms which are not interconnected to form a single centrally monitored system – often referred to as ‘islands’ of video. The IndigoVision solution has created a fully scalable and distributed solution that will allow the future integration of these remote control rooms into one unified system, allowing Hong Kong’s Traffic Police to centrally manage and control the region’s traffic problems.
Expansion plans
Plans are in place to expand the system to over 700 cameras. The first phase of this expansion has been completed with the addition of a 48 camera IP-based system to monitor the Northern district of the city, which was previously not monitored. This region is close to the Chinese border and has significant traffic problems caused by 2 million people a day making cross border journeys.
Even though the new extension to the system is predominantly for traffic surveillance the Police also use it for monitoring public events in the area.
IndigoVision’s Software Interface Kit (SIK) was used to develop an interface for uploading video images to the Traffic Department’s website, allowing the public to view selected traffic cameras. IndigoVision uses the SIK to develop interfaces for many third party systems including leading access control systems, to create an integrated solution for IP security applications.
Each of the analogue camera feeds are connected to IndigoVision’s 8000 transmitter/receiver modules, which converts the signal to 4CIF 25 fps digital video for transmission over the network. The ‘virtual matrix’ can switch any camera feed to any PC or monitor, wherever they are located on the IP network.
