5.2 Sensor field of view
5.2.1 Types of field of view
During the configuration phase, for each sensor it is possible to select the angular coverage of the field of view:
l 110°
l 50°
The actual detection field of the sensor also depends on the sensor installation height and inclination. See
"Calculation of position for sensor height ≤ 1 m" on page56 and "Calculation of position for sensor height > 1 m"
on page60.
5.2.2 Features of the 50° field of view
For the access detection function, the 50° field of view makes the sensor more resistant to interference from
materials such as iron and water, which reflect the radar signal (e.g. iron shavings, water splatters, rain). It is
therefore also suitable for outdoor installations.
WARNING! When the restart prevention function is active all the sensors have a 110° angular
coverage, regardless of the set angular coverage.
NOTICE: during the configuration phase, take this aspect into consideration to avoid generating undesired alarms.
5.2.3 Areas and dimensions of the field of view
The sensor field of view is composed of two areas:
l detection field [A]:where detection of objects similar to humans in any position is guaranteed.
l tolerance area [B]:where the actual detection of a moving object/person depends on the characteristics of
the object itself (see "Factors that influence the reflected signal" on page31).
