Motion detection function
The detection of movements is done through the "passive infrared" principle ("PIR"). The device
generally reacts to heat radiation changes within its detection area. This is achieved with the
help of the so-called PIR sensors, which are highly sensitive in the infrared range. The
geometry of the detection field is ensured by a lens system that lets infrared light pass through
and concentrates incident radiation on the sensors. So-called "detection radiation" are formed
through the lens system and cause a clear signal jump to be detected when they enter.
Note: The term "detection radiation" refers to the imaginary line that begins in the sensor, goes
through the lens system and continues in a straight line outside of the device. The device itself
does not emit any radiation.
Figure 3: Thermal image of a person and their reflection on the ground
The detection of heat sources through a motion detector is influenced by the following criteria:
- Geometry of the detection field:
A motion detector that faces downwards at an angle is different from one that looks straight
ahead into infinity (Figure 4).
- Distance between heat source and motion detector: the further away the heat source is
from the sensor, the weaker the evaluable signal on the sensor (Figure 4).
- Size of the heat source, e. g. adult or child (Figure 5)
- Temperature of the heat source: surfaces at 37 °C radiate more intensely than at 10 °C
(Figure 5).
- Contrast between the heat source and the environment: if the heat source radiates just as
intensely as the environment. detection will be significantly more difficult (Figure 5).
- Speed of movement: a faster moving object produces clearer signals in the sensor.
- Direction of movement: if detection radiation passes tangentially, this typically results in an
abrupt sensor signal which can be evaluated well. However, if a heat source moves radial
to the sensor, the sensor signal changes happen more slowly. This makes differentiation
from the background noise significantly more difficult.
- Concentration of the detection field: the number of sectors and switch segments of the
detection field determines the the concentration of the scan and therefore the response
behaviour.
- Sensor sensitivity: the sensor sensitivity can be adjusted according to application and
environment. Low heat contrasts outdoors may require a high sensitivity that is far to high
for indoor use. The sensitivity should be decreased in this case.
- Environmental medium: high humidity or rain can negatively influence the permeability for
infrared radiation.

distance law)

Interference sources for motion detection
In addition to the mentioned effects, other objects within the detection area could also trigger
the motion detector, e.g.:
- Heat sources such as heating units, outlets from ventilation openings or air conditioners,
copiers, printers, coffee machines, etc. (Figure 6)
- Draughty doorways
- Incandescent lamps when switching on or off
- Animals, e.g. stray cats
- Reflections on reflecting surfaces (Figure 3)

Some of the mentioned effects can be compensated for using intelligent filter switches by
calibrating the received signals with typical motion patterns. Selecting the device and
installation location should be made so that the detection field is suited for the intended
purpose.
Technical information and statements
On the one hand the effective range of motion detector applications is affected by a wide range
of factors – however, specifications in the technical data typically come out very precise. These
specifications generally refer to the normal area of use of the device. For flush-mounted motion
detector we assume the typical interior situation in a functional building with moderate ambient
conditions, at a temperature of about 18 °C, average humidity, used in a hallway with walking
people.
Higher ranges are to be expected for:
- lower ambient temperature (note season specific clothing)
- more intense movement of persons
- reflective surfaces
Lower ranges are to be expected for:
- higher ambient temperatures, where people move less and there is more heating, such as
is the case with meeting rooms, classrooms, waiting areas and office environments
- significantly cooler ambient temperature, when clothing has a thicker insulating effect
- Direction of motion to the motion detector for ("radial detection")
- rising terrain that limits the geometry of the detection field.
