IndigoVision IP Video monitors National Rail Network
IndigoVision's IP Video technology is being used as part of a new CCTV system for Amsterdam's Central Station complex
IndigoVision's IP Video technology is providing an innovative integrated wireless CCTV solution for Amsterdam's Central Station.
The requirement to extend the existing analog CCTV system at the station with an additional 20 dome cameras highlighted the drawbacks with traditional cabled video systems. The cost to install these remote cameras, with traditional fibre/coax cable, around the vast station complex was prohibitive. Q-CAT, a local Dutch security and communications specialist, in co-operation with IndigoVision developed a scheme using an extension to the existing IT network infrastructure. The analog video-feeds from the new dome cameras are converted to MPEG-4 high quality digital video by IndigoVision's 8000 transmitter units. The IP datastream from the 8000 devices is then transmitted via Wavesight's WaveMAX wireless Ethernet bridges to the Station's Security Control Centre (CTR). Here, several WaveMAX receivers/antennas convert and feed the digital transmissions from each camera onto the new local IP network. The system is bi-directional allowing camera control data to be sent to each camera over the wireless network.
This innovative wireless approach allows the existing network to be extended to all parts of the station complex without the need to install cable. Within the station CTR both IndigoVision's 'Control Center' video and alarm management PC software and dedicated Network Video Recorders (NVR) are installed on the IP network. Four NVRs provide continuous recording at 25fps from each of the dome cameras. The 'Control Center' software allows the operators to view live and recorded video from any camera on the network, either directly from the camera or from the NVR. An IndigoVision IP video receiver rack is also installed on the network in the CTR to convert the camera feeds back to analog so they can be connected into the matrix hardware of the existing CCTV system.
The dome camera feeds are also transmitted over a point-to-point wireless link from the CTR to the local police control center 600m away. Again IndigoVision's 'Control Center' software is installed and is integrated with the existing CCTV monitoring equipment. The police can view live and recorded video and control the cameras independently from their remote control center. The new camera feeds are also made available to the main CCTV system of the Dutch Rail System.
This project highlights the flexibility and benefits of a wireless IP Video solution. It provides a very cost-effective way to expand existing systems and provides a simple interface into any traditional CCTV configuration.
