System uses a processor unit connected to the sensitive cable via a variable length of non-sensitive fibre optic cable.
This makes the system extremely flexible in hardware configuration, with options to locate the processors centrally or distributed around the fence line, dependent on the site cabling infrastructure.

The system is particularly suited to deployment in the protection of gas, water and oil pipelines and can use spare fibres contained within existing optical cables currently used for data transmission along the pipe, above or below ground. It can also be used to protect very long perimeter fences and to detect the theft of copper cables from underground ducts.

SUN is a fibre optic system that gives protection against removal of solar and photo-voltaic panels. The system protects the panels by joining them together using a low cost fibre optic cable.
