VideoJet 100
Average n(frames):
Here the number of pictures is set, in which a motion has to be
detected to trigger an alarm. This is to prevent the triggering of an
alarm e.g. because of a bird passing by quickly.
Object min size [n*n blocks]:
Here you choose how many cells in the frame a moving object must
fill at least to trigger an alarm. You can set values between 1*1 and
6*6, but it is requested to set a minimum value of 2*2.
Alarm indicator:
The sensitivity of the video sensor can be adjusted so that an
alarm is only triggered after exceeding the threshold you can pre-
set in this window. By this you can filter the noise of the camera for
example.
To do so control the movement of the curve for a sufficient time
with changing lighting after you have set the parameters. Then
click on the threshold (blue horizontal line) with the left-hand
mouse key and drag it to the height at which you want the alarm to
be triggered when the curve is traversing (displayed in red); all
movements below the threshold (displayed in green) don’t trigger
an alarm:
