F.A.Q.
7.3 F.A.Q
Some further questions and doubts may be raised during the Area Monitor
operation.
Where to place an area monitor?
The placement of an area monitor is a compromise between a non-easy
access site, to avoid possible vandalism, and a place that requires
continuous monitoring.
Normally a roof, a very large terrace, an open place and on a straight
surface, is the place that is most advisable.
For example, in case of a hospital or a kindergarten, why not put the
instrumentation where people are?
As already explained, the instrumentation must be in a place not easy to
access.
This is to avoid accidental damages from children’s games such a balls or
something else, possible signal influences caused by the passage of people
with special equipment or who simply speak on the cell phone. Possibly
avoid placing the control unit where it can be easily subjected to vandalism.
We also have to consider that signals we are going to monitor come from
antennas, high voltage trellis, a technology that radiate even for miles. If the
signal, we are detecting, on a roof is already low, it will be even more inside
the building or at a distance greater than the emission point.
Instead, if the detected signal is near or exceeds the limits that is the area
where we will have to investigate with more specific, selective equipment.
Exactly, once on a roof or a terrace, where and how does the control
unit be installed?
First of all we must remember that the area monitor is powered by batteries
that are recharged during the day thanks to its solar panel. Then the first
thing to do is to choose a sunny place and point the solar panel in the SUD
direction, if possible, or at least avoid positioning it completely toward
NORTH.
Verify the presence of any objects or constructions around them does not
create a shadow that will undermine the work of the solar panel.
Avoid places too close to large metal objects, or any objects that may
interfere with the electromagnetic field, invalidating the measurement.
Where possible, it is good to install the area monitor at a certain distance
from walls, palaces, pillars, high voltage trellis or other similar objects.
