Many large sites provide unique challenges.
Often they have very large perimeters, contain potentially explosive or corrosive materials, or are located in both remote and residential areas. The Fiber Defender Series 200 is ideal for use on these perimeters to detect cutting and climbing of a fence. Alternately, the sensing cable can be buried to detect vehicular approach in open areas or walking trespass in beach areas. The fiber-optic sensor cable is jacketed with a tough polyurethane cover to ensure a long life in the presence of water, salt water, and many corrosive chemicals. The sensing cable is mounted in a PVC split conduit to mount on long zones of this refinery fence.
