More than four million tons of cargo and over four million passengers pass through the port every year, so safety and security are paramount to the port’s operation. 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.
The CCTV system includes numerous dome cameras, providing high-quality digital images via a wireless WiMAX LAN, which spans about a six-mile area around the port. Cameras provide surveillance for the main entrance, parking lots, the port’s rail network, the docks and the approaching seaways.
A mobile CCTV vehicle is also in operation, providing flexible surveillance quickly and easily to any area around the port. The vehicle is based on a standard sedan and is equipped with a range of environmental sensors, for measuring parameters such as radioactivity and toxic gases, as well as a wireless 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.
‘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. Recording is carried out using three of the company’s 800Gb RAID-configured networked video recorders (NVRs). Each dome is pole-mounted and connects to an IndigoVision 8000 transmitter/receiver unit installed with the camera. The 8000 unit converts the camera signal to high-resolution digital video for transmission over the wireless LAN.
The system also features an Activity Controlled Framerate (ACF) function. This reduces the video frame rate during periods of scene inactivity, which minimises bandwidth demands on the wireless LAN and NVR storage requirements.
