Mounting
the device is not limited to a mounting height of 3 m.
To reduce the risk of a false alarm being triggered,
the device must not be exposed to incident light
e.g. caused by sunlight or car headlights, nor
must it be mounted in the vicinity of a heat source
(above a radiator, for example).
The eectiveness of the detection procedure de-
pends on the temperature dierence between
the moving object and the relevant background.
The detection range should be aligned to the
floor, but not directly to a window, radiator or
other heat source.
In general, it is not possible to detect motion
through glass. False alarms caused by moving
heat sources behind a window cannot be
excluded by 100 %.
