The noise level is used as a threshold for distinguishing between noise and motion., The noise level is used as a threshold for distinguishing between noise and motion.

This is different from the threshold parameter. This is changes at pixel level. The purpose is to eliminate the changes generated by electric noise in the camera. Especially in complete darkness you can see the noise as small grey dots that come randomly in the picture. This noise can create false motion detection. What this parameter means is that the intensity of a pixel must change more than +/- the noise threshold parameter to be counted
