Concept
Fence
Summary
A fence is a structure that encloses an area, typically outdoors, and is usually constructed from posts that are connected by boards, wire, rails or netting. A fence differs from a wall in not having a solid foundation along its whole length.
Alternatives to fencing include a ditch (sometimes filled with water, forming a moat).
Agricultural fencing, to keep livestock in and/or predators out
Blast fence, a safety device that redirects the high energy exhaust from a jet engine
Sound barrier or acoustic fencing, to reduce noise pollution
Crowd control barrier
Privacy fencing, to provide privacy and security
Temporary fencing, to provide safety, security, and to direct movement; wherever temporary access control is required, especially on building and construction sites
Perimeter fencing, to prevent trespassing or theft and/or to keep children and pets from wandering away.
Decorative fencing, to enhance the appearance of a property, garden or other landscaping
Boundary fencing, to demarcate a piece of real property
Newt fencing, amphibian fencing, drift fencing or turtle fence, a low fence of plastic sheeting or similar materials to restrict movement of amphibians or reptiles.
Pest-exclusion fence
Pet fence, an underground fence for pet containment
Pool fence
Snow fence
School fence
A balustrade or railing is a fence to prevent people from falling over an edge, most commonly found on a stairway, landing, or balcony. Railing systems and balustrades are also used along roofs, bridges, cliffs, pits, and bodies of water.
Another aim of using fence is to limit the intrusion attempt into a property by malicious intruders. In support of these barriers there are sophisticated technologies that can be applied on fence itself and strengthen the defence of territory reducing the risk.
The elements that reinforce the perimeter protection are:
Detectors
Peripheral alarm control unit
Means of deterrence
Means for communicating information remotely
remote alarm receiving unit
Brushwood fencing, a fence made using wires on either side of brushwood, to compact the brushwood material together.
