8.12.2 Particolar conditions
1.
Ground conditions:
It is inadvisable to install the equipment along sections with tall grass
(more that 10cm), ponds, longitudinal waterways, and all those types of grounds whose structure
is rapidly mutable.
2.
Obstacles:
the fences, are generally metallic therefore highly reflecting hence causing various
problems, for this reasons some precautions are suggested:
First of all, make sure that fence has been properly fixed in order that the wind does not
move.
If it is possible the microwave beam shouldn’t be placed in parallel to a metallic fence, is
necessary to create a corner with it
Metal fences placed behind the equipment night cause distorsions to the sensitive beam
especially, and might cause movement detection in unexpected spots, with subsequent
likely generation of false alarms.
In case of Mw barrier should be installed in a corridor between two metallic fences, the
width of the corridor should be necessary not less to 5m.
Along the section, within the area of the protectiion field, are allowed pipes, poles or similiar as long as
their dimensions, with respect to the protection beam, are not too excessive. The trees, hedges, bushes in
general, need very great attention if near or within the protection sections.
