How do I set up the “Motion Detection “settings and what is the specific relation between “Sensitivity” & “Percentage”?
There are two parameters in the motion detection settings: Threshold and Percentage. Pixel difference between two continuous images are calculated and compared to the parameter value “threshold.” If the difference is larger than the threshold, this pixel is marked as “alerted”. The processes will be done for all pixels in the motion detection window. A higher sensitivity will detect slow movement more easily while a low sensitivity will only detect fast movement. If the percentage of the “alerted” pixels is larger than the parameter value “percentage,” the window will be indicated as motion occurred. A low percentage will detect objects that are smaller relative to the window size and a high percentage will only detect objects that are larger relative to the window size. In the example, the pixels that are different from the first image and the second image are found (highlighted boxes). Each of these pixels is compared with their corresponding pixel in the other image and if the diffe
