Wireless CCTV Surveillance System Protects Malaysian City

IndigoVision : 07 July, 2011  (Application Story)
Large scale wireless CCTV system with central monitoring based on Control Center from IndigoVision deployed in Subang Jaya in Malaysia
Wireless CCTV Surveillance System Protects Malaysian City


Subang Jaya Municipal Council (MPSJ) has deployed a fully-integrated wireless CCTV surveillance system using IndigoVision’s IP Video technology. MPSJ administrates the city of Subang Jaya, which has a population of 4.7 million and is located in the state of Selangor on the west coast of Peninsular Malaysia. This is the first large scale deployment of centrally monitored CCTV cameras by a local municipal council in Malaysia. The 100 camera system was designed and installed by IndigoVision’s approved Partner GTC Global Sdn Bhd, who specialise in deploying integrated wireless security solutions.



“We needed a reliable IP-based video surveillance solution that could be deployed across large areas using wireless broadband networks,” said Mr. Imran, Director of GTC Global Sdn Bhd. “IndigoVision has supplied wireless IP Video systems for many city-wide surveillance projects around the world, making them an ideal partner for this project.”



Video from 90 PTZ and fixed cameras, as well as 10 mobile units, is streamed back to MPSJ’s purpose-built command centre, where the council’s enforcement officers can observe in real-time traffic congestion, criminal activity and public safety. At the heart of the command centre is a large wall-mounted Graphical Information System (GIS) display that allows users to zoom in on individual residential and commercial addresses. Through an interface with the IndigoVision system, video can be overlaid on the GIS display to help improve situational awareness. Individual operators use multi-monitor PC workstations running IndigoVision’s ‘Control Center’ software, which provides a powerful suite of features to view and quickly analyse live and recorded video.



IndigoVision’s class-leading compression technology allows high quality video to be transmitted over an area in excess of 160km² using Motorola’s Wireless Broadband Point-to-Multipoint 100 Series system. The 10 mobile camera units can be temporarily installed at local hot-spots and be quickly operational using a wireless link. The command centre is also connected via dedicated wireless links to the Selangor police headquarters in Shah Alam and the Subang Jaya police district headquarters at Seri Kembangan. This allows live and recorded video from any camera to be viewed and analysed by the police using their own ‘Control Center’ workstations. This helps improve overall incident response without the need for police officers to be stationed in the command centre.



“The system has been delivered to MPSJ on a rental-lease basis, where we have purchased the equipment upfront and the council pays a yearly lease to operate the system,” continued Mr. Imran. “The reliability of the system and IndigoVision’s excellent technical support is of utmost importance to us as the lease would be terminated if the system does not work.”



‘Control Center’ incorporates integrated alarm management functionality, which has been put to good use by GTC Global Sdn Bhd. When the local equipment cabinet is opened an alarm is triggered via a digital input on IndigoVision’s IP Video transmitter unit, which is installed next to each camera. This instantly alerts an operator by identifying the location of the alarm on a ‘Control Center’ map screen. Video from the local camera can then be viewed to monitor the situation.



All cameras are continuously recorded using IndigoVision’s Windows Network Video Recorder (NVR) software with 30TB of Raid 5 storage, giving a 30 day archive. The overall storage requirement and bandwidth demand on the wireless network is reduced through IndigoVision’s advanced compression technology and a unique feature called Activity Controlled Framerate (ACF). Built into IndigoVision’s IP transmitters, ACF allows video to be streamed at a lower framerate when the camera scene is inactive and then instantaneously ramps to the maximum configured framerate when motion is detected.
