IndigoVision, the leading supplier of end-to-end IP Video solutions, is providing its technology as a backbone for a new integrated traffic monitoring system for Bangkok's outer ring road network. Existing toll plaza CCTV surveillance systems located across 75km of the ring road have been integrated into a new central control room. Staff in the control room can now view high-quality video from inside and outside of the four toll plaza complexes, providing central monitoring for traffic management and staff safety.
Analogue video feeds from the 64 existing dome and fixed cameras are connected to IndigoVision's 8000 transmitter/receiver modules locally at each toll plaza. The 8000 converts the camera signal to DVD quality, high-resolution digital video for transmission over the newly installed gigabit Ethernet LAN. IndigoVision's advanced MPEG-4 compression technology ensures that the control staff receive CCTV images that are indistinguishable from analogue while minimising bandwidth on the LAN. Further 8000 modules are installed in the control room to convert selected camera feeds back to analogue for display on one of the 16 wall mounted monitors. The system was supplied by Industronics and their partners in Thailand, Smart Traffic Co. Ltd.
"This application is one of many traffic monitoring systems that IndigoVision has recently implemented," said Dr Oliver Vellacott, IndigoVision's CEO. "Traditional analogue CCTV technology is just not suited to the long hauls involved in wide-area surveillance such as with road and rail networks, ports and airports. IP Video systems are extremely scalable, for example a new camera can be added at any point on the network, at any time, without new cabling."
IndigoVision provides end-to-end standalone solutions for digital video management for systems of any size through its Network Video Recorders (NVRs) and ‘Control Center'
enterprise video and alarm management software. However, as this application demonstrates, IndigoVision's IP Video technology is also suited to the simple point-to-point transmission of CCTV images over large distances. This enables video from remote cameras to be simply converted back to analogue and interfaced into existing control rooms.
