The CCTV system includes numerous dome cameras, providing high-quality digital images via a wireless WiMAX LAN, which spans an area around the port of over 10km2. The cameras provide surveillance for the main entrance, car parks, the port's rail network, the docks and the approaching seaways. In addition the port operates a mobile CCTV vehicle that provides flexible surveillance quickly and easily to any area around the port. The vehicle is based on a standard saloon car and is fitted with a range of environmental sensors, for measuring parameters such as radioactivity and toxic gases, as well as a wireless CCTV camera and monitor. Should a large or unusual ship enter the port the vehicle can be dispatched to monitor the event in areas that are not covered by the fixed cameras. Local systems integrator Taitotekniikka worked with IndigoVision to design the system which resulted in considerable savings for the port operator compared with a traditional analogue CCTV solution.
'Control Center', IndigoVision's enterprise video and alarm management software, allows the security staff at the central control room to view live and recorded video from any of the cameras. In addition the control room staff use analogue monitors and keyboard/joysticks to complement 'Control Center'. Recording is achieved using three of IndigoVision's 800GB RAID configured Networked Video Recorders (NVRs).
Each dome is pole mounted, high above the ground, and connects to an IndigoVision 8000 transmitter/receiver unit installed with the camera. The 8000 converts the camera signal to DVD quality, high-resolution digital video for transmission over the wireless LAN. IndigoVision's advanced compression technology ensures that the security staff can view and record CCTV images that are indistinguishable from analogue whilst minimising bandwidth on the wireless LAN. The system also uses IndigoVision's Activity Controlled Framerate (ACF) built into the 8000s. This reduces the video frame rate during periods of scene inactivity, which minimises bandwidth demands on the wireless LAN and NVR storage requirements.
