The CCTV subsystem is designated for local and remote surveillance of station areas (entrances, paid and unpaid areas, platform and access to platform), depots (entrances, garage shed, handover platforms), extra-sites as for security reasons (depot fence, emergency call points). The coverage quality philosophy is developed based on the ROTAKIN Standard that uses a 1.6m target high and giver %R of the height of the screen: 5%R – Monitor, 10%R – Detection, 50%R – Recognition and 120%R – Identification. The system concept is based on full IP CCTV (Generation 3) and comprises the following equipment: Station/Depot/extra-sites– Cameras, NVR, SEB, CCTV LAN Switch, Decode Vega Box; emergency exit points cameras, Electro-optical encoders; Control Centre– CCMS, Management Workstation. The system will be operated from ‘Command and Control’ Workstations located at: Station , Depot, Extra-sites, Control and Command Centre, Police Headquarter. The images will be displayed on dedicated monitors of the ‘Command and Control’ Workstations (system integrator). Parameters proposed through design: 10%R coverage for platforms and concourse area, 50%R at the entrances, 120%R in front of cash points. Technical solutions in modern transport infrastructure 6

  13. 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.

  17. 17. The TDS is designated to provide an accurate time synchronisation for all systems and display the time information for the public and operating personnel in Transport Infrastructure. In order to ensure accurate clock synchronisation, the system is equipped with a GPS-synchronised that distribute the correct time under NTP v3 protocol. Analogue and digital clocks will be synchronised from either Master Clock / Sub-Master Clock and be installed at Station, Depots and MPS. Synchronization hierarchy includes the following chain: GPS → Mater Clock, Master Clock → Sub Master Clock, Sub Master Clock → Slave Clocks. The interface to other subsystems will take place via NTP protocol and ‘Data Network’ physical connection. Technical solutions in modern transport infrastructure 17

  19. 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’.

The Intruder Detection is designated to provide the functions of access control, access management and intrusion detection to critical areas in: Command and Control, Stations, Depot, Extra-sites. The aim of intrusion is to detect unauthorized access or authorized person trying to gain access inside controlled areas and raise alarms. Deployment of sensors, controllers, detection devices and locking mechanisms is done wherever is required. Field elements utilized: Motion Detector, Glass Break Detector, Magnetic Contact Door, Proximity Card Reader, Override Key Switch, Exit Push Button, Intrusion Zone Key Switch, Reader Module, Input Module, Electromagnetic Lock.

  24. 24. The FON is build in order to provide the necessary capacity of cable and transport all required communication between the different sites of the Transport Infrastructure: Stations, Depots, Command and Control, Extra-sites. The FON provided is fully resilient, including two segregated cable routes named ‘Seaside’ and ‘Landside’. If a failure occurs, the second cable will ensure there will not be communication disruption. The FON comprised following types of cables: Operational, designated to connect station and support connectivity of MSN. The FON is designed to ‘100% spare capacity principle. In some particularly areas, the Contractor’s design indicates dual resilience by employing two separate and diverted routes to the SER. All fibre optic cables are terminated into ODF inside of SER, MPS, DCER, CCER, EEP/EES. The WiFi design cater for intermediate FO distribution boxes. The ‘Operational Fibre Optic Cable’ size is variable, between 24 to 60 cores. Technical solutions in modern transport infrastructure 24

  26. 26. Commercial advertising allows advertising and information to be displayed at all stations and trains. A central server at the ‘Command and Control’ collects either live television through cable, or imports media files from DVD, external hard drives etc. The central server distributes the files to each station and train for localized playback (IP TV). Each station and train own a local server capable of storing up to 12 hours video and audio, various formats. The system also supports pseudo-live streaming of television from the ‘Command and control’ to all displays. Data Network is employed for transfer of live images or update of recorded video content between ‘Command and control’ and Station.
