LINE_Fence 2
Optical fiber woven into the meshLINE_Fence 2 turns your fence into a sensor. The optical fiber is woven through the openings of the chain-link mesh, and the analyzer raises an alarm as soon as movement of the mesh reaches the fiber.
The operating principle.
When someone pushes, pulls or cuts the mesh, its wires exert small forces on the optical fiber. The analyzer measures the change in light and raises the alarm.
The fiber doesn’t need to be touched directly. It is enough for the movement of the mesh to act on it. That is what sets the technique apart from vibration sensors, which also react to sounds from a distance.
The level of protection is set in the site study by the number of fiber lines. For a 2 m fence: one line for basic monitoring, two for the standard application, three or four for higher requirements. There is no upper limit.
Typical applications
- Solar parks
- Industrial sites and warehouses
- Water and fuel tanks
- Mobile telecom sites
- Remote sites without CCTV
What you get with LINE_Fence 2.
Alert before entry
The alarm is raised while the intruder is still on the fence.
In all weather
Detection relies on mechanical disturbance of the fiber, not on sound or vibration from a distance. The fiber carries no current and is immune to electromagnetic fields.
Follows the terrain
The fiber follows slopes, corners and curves in the fence without extra analyzers.
Takes up no space
Mounted on the existing mesh. No security strip is needed inside the property.
Chain expansion
The fiber returns to the same analyzer or continues to the next. Analyzers are not electrically connected to each other.
Easy repair
No connectors, no expensive instruments. The fiber is cut with the tool and goes straight into the device.
Key specifications.
Full details in the datasheet.
In a solar park, LINE_Fence 2 guards the perimeter and INFI_Sense 2 guards the panels. SUB_Sense 2 covers gates and openings where there is no mesh.
