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 (see figure 1) up
to (see figure 10)
Direction of movement : Passing the motion detector tangentially results in a heat
signal which can be evaluated well. If movement is radial to the sensor, the heat sig-
nal 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 environ-
ment and the intensity of the heat motion.
