  • 13. TI WiFi is used to access the on board CCTV system, download of pre- recorded CCTV, IP TV (Commercial adverts), backup of critical video files (SAN), transmission of vehicle alarms. An operator at the Command and Control or Police HQ can view the CCTV cameras live or access pre-recorded material from the on board CCTV Server.. The system uses the IEEE 802.11g standard (2.4GHz) translated to proprietary band. A series of access points deployed along the track provide continuous radio coverage. The train ‘hops’ from access point to access point to provide seamless IP communication between the train and ground at a minimum of 6MBps throughput. Each access point (AP) is connected to an adjacent station via fibre optics and layer 2 switches. The Wireless LAN Controllers are allocated to control and manage the flow of data from each access point. The data is then forwarded to the operator for viewing.

  • 19. The Voice and Video Recorder provides recording and archiving of audio and video from the TETRA, Telephone and CCTV. Build up based on FCH SAN architecture and principles. All telephone and TETRA calls involving ‘Command and Control’ operators are recorded. CCTV ‘events’ are recorded (with adjustable pre-amble) which are either operator initiated or automatically triggered from events such as EC calls, IAS alarms etc. The VVR is four ‘layer’ architecture as follows: Recording Layer, Backup Layer, Archive Layer and Playback Layer. Once the files are recorded at the Recording layer, they are passed to the Backup layer where they are processed before being stored at the Archive layer. The Playback layer provides search and retrieval functionality and synchronizes the video and audio from ECB calls. The Archive has been dimensioned for 30 days worth of recording. Statistical assumptions have been made in order to calculate the size of the disks. Approx 27TB of storage is provided at both the ‘Command and Control’.
