• Distances
  Ports cover significant areas, which result in substantial transmission distances. To achieve sustained and reliable operation the systems had to rely on an optical fibre infrastructure.
  
  
• Harsh Environment
  Sea water, high tides and bad weather, are all elements that had to be taken into account when deciding on the appropriate external components such cable, cabinets, transmission equipment, etc.
  
  
• Resilience
  Ports are industrial units where heavy-duty machinery is commonplace and accidents can cause major disruptions. To provide a secure and resilient network, a self-healing fibre optic ring topology was proposed and established for both the Access Control and CCTV elements of the design.
  

A CCTV fibre optic system was the ideal solution to meet these issues. The many Benefits of CCTV technology include:

• Optical Fibre Ring Topology
  Any point of failure does not result in a total loss of service when the transmission equipment incorporates a self-healing mechanism. Transmissions in a clockwise direction will simply be re-routed in an anticlockwise direction.
  
  Each fibre core has two routes between any termination point on the ring and the controller – clockwise route and anticlockwise route. This effectively halves the fibre core count required on each site and makes full us of the available capacity.
  
  
• Real-time Full Bandwidth Video
  All video transmissions have been installed using a point-to-point connection between the camera location and the control room. This approach retains a full bandwidth high quality video signal, which is continually available.
