Motion detection
The detection of heat sources through a motion detector and thus the extent of the detection
field is influenced by the following criteria:
Geometry of the detection field, assembly height and set sensitivity (Figure 1) up to (Figure 8)
Direction of movement: If motion detector passes tangentially, this results in a heat signal which
can be evaluated well. If movement is radial to the sensor, the heat signal is smaller and thus
harder to evaluate, resulting in a smaller range.
The following specifications on the extent of the detection field are general guide values.
Discrepancies can occur depending on the installation environment and the intensity of
the heat motion.
