2.3.2 Range of the field with
vertical sensor direction (barrier)
In this installation the visual field of the sensor is
approximately 30° along the horizontal plane and
70° on the vertical plane. It extends for a
maximum of 20 m, following the radiation pattern
of the antenna.

2.3.3 Calculation of the field of
vision
The actual field of vision of the sensor (detection
start and end,
s
1
and
s
3
) depends on:
l
sensor installation height (
h
)
l
sensor direction (horizontal or vertical)
l
sensor inclination (
α
)
Within the field of vision, discernment of animals is
guaranteed up to a certain distance from the
sensor (
s
2
). For details about discerning animals,
see "Set the tolerance level for animals" on
page 22.
Based on a specific installation height, there are
direction and inclination combinations that
guarantee optimum performance. Some
examples to better explain the effects of height
and inclination are presented as follows.
2.3.4 Sensor installation height
The sensor can be installed at any distance from
the plane to be monitored, from 0.5 and 3 m (from
1.6 to 10 ft). For example, it can be installed at 2 m
from the floor or 0.5 m from the jamb of the
window frame.
When installing the sensor, consider the risk of a
blind spot: if the sensor is too high, it must be
tilted downwards to reduce the undetected area.
However, this also reduces the maximum detected
distance. If the sensor is too low, the blind spot is
minimal, but it increases the risk of masking
caused by accidental passage of people.
2.3.5 Examples of the field of
vision with horizontal sensor
direction (volumetric)
NOTICE
: the detection start and end values do not
guarantee detection of a standing person. The
reported values may slightly vary based on the
installation conditions.
Note
: only some heights are reported, but every
intermediate value is allowed and guarantees optimum
performance.
The dimensions of the field of vision expressed in
meters and feet are as follows.
