Moving crosswise toward the device
1m
Fig. 19: Detection crosswise to the device
The detection range is at its highest when the person to be detected moves crosswise toward
the device. This is called a tangential direction of movement.
The detection of the infrared change functions best when the person to be detected moves
crosswise to the viewing field of the device. Here, for example, it crosses several sectors at a 1
m path. If the person moves directly towards the sensor, it takes longer before the person is
detected by the device in other sectors.
In the right example graphic, the person touches 6 new sectors at a 1 m path.
