IP video has been deployed as part of a CCTV central monitoring and recording project for First Capital Connect (FCC), one of the UK’s newest train operating companies, or TOCs.
FCC operates trains between London, Brighton, Bedford, Peterborough, Cambridge and King’s Lynn over the UK’s busiest rail network. As part of its five year, £8m, network-wide Station Improvements Programme, FCC selected IndigoVision and its partner ATEC Security to install a new IP-based video, recording and transmission system. Upgraded were 1,194 analogue CCTV cameras across 63 train stations, now all monitored at a new central control room at Enfield, using the company’s existing network infrastructure.
The challenge was to bring together the various local and independently monitored analogue CCTV, to monitor and manage them centrally. Existing CCTV had to be fully operational while the new IP-based solution was installed. IndigoVision’s compression and bandwidth management technology were vital for a project of this size, according to the firms. Multiple video streams from each camera can be configured for different applications, for example, high-framerate/high-bandwidth for recording and local viewing and low bandwidth for remote monitoring over the WAN.
Use of software
Control Center’ IndigoVision’s enterprise IP Video and alarm management software, is used by operators, both locally and in the central control room to view and analyse live and recorded video. A ‘Control Center’ workstation can be located at any point on the network and allow an operator with the right permissions to view video from any camera or NVR no matter where they are located. As ‘Control Center’ software is licence-free, workstations can be deployed for no more than the cost of an entry-level PC.
Thanks to research and development by ATEC Security, a new server platform enabled over 100 IndigoVision Windows-based Network Video Recorders (NVRs) to be installed at the 63 train stations and throughout the network, providing 31 days of recording using a total of 473 terabytes of RAID 5 storage. Special server configurations were developed that allowed physical discs to be replaced in the event of a major incident, where quality evidential video is required for analysis and investigation by police and others.
Some 947 fixed and 95 PTZ cameras are each connected to an IndigoVision 8000 IP Video transmitter/receiver module. The 8000 converts the analogue camera feed to DVD quality MPEG-4 digital video for transmission over the network. IndigoVision’s advanced compression technology allows low-latency video to be transmitted around the network using FCC’s WAN. The combination of the network and ‘Control Center’ creates a virtual matrix that allows video feeds to be ‘switched’ to any workstation or NVR. This replaces the many original local analogue hardware matrices and removes the ‘islands of video’ that have come to represent the fundamental shortcoming of large scale analogue CCTV systems, according to the IP firm.
This project is just one of many large-scale infrastructure projects that IndigoVision has deployed for the rail industry, including the Berlin S-Bahn, the Dutch National Rail network and the 900-plus camera system for SkyTrain, a light rapid transit system in Vancouver, Canada.
