required to generate an alarm.

feature of the video sensor.
Tracker
In the Tracker field you see an arrow, which indicates the current
motion in the video image. By means of check boxes in the four cor-
ners, the desired direction can be activated. If, for example, all
movements to the "left" and "upwards" are to activate an alarm,
then mark the top left corner. If all movement to the "left" is to acti-
vate the alarm, then check the left upper and the lower left corners.
"
Note the movements indicated by the arrow in the video image over
a long period and at all light levels likely to be encountered in prac-
tice.
"
Click the check box in order to activate the corresponding direc-
tional component.
