Trigger threshold
Look at the moving object entering the area of motion detection: although moving quite
slowly, it caused motion activity – several pixel regions reported a motion that was faster than
allowed “speed limit” of sensitivity (70).
The blue graph on the right side of the image shows how many percent of pixels within the
motion detection region were considered as “currently in motion”. The activity panel itself is a
timeline – for each moment of time you can see the height of the blue bars. You may notice
that at certain moment the tallest bars in the activity graph reached about 25% (a quarter of
the total height in activity panel) – it means, 25% of this motion detection area were filled with
moving pixels at that moment. By visual observation you can also see that the object
standing inside the motion detection region indeed covers about 25% of its size.
What if the object is really small but moves rather fast (gets triggered by the current
sensitivity level)? For example, we want to detect people but not the cat walking in the room.
Although both people and cat may move with the speed that will trigger motion, they have
different size of triggered pixels. For example, a human passing by the motion detection
region will trigger 25% of pixels in that region while the cat would trigger only 2%. Since we
want to have a real alarm in case of human or vehicle passing by while ignoring birds, cats,
butterflies, mice, etc, we need a filter that can define how many percent of triggered pixels
will be considered as a real alarm. This parameter is called trigger threshold. The default
value of trigger threshold is 10%. It means, only the objects that are bigger than 10% of the
