Video noise
Video noise.
Description
Video noise
When the camera captures video frames in a dark environment, it is possible that the electrical background noise of the CCD video cell creates fake motion detection events.
It is possible to reduce the sensitivity of to the video noise by enabling the ReduceVideoNoise property.
Usually this saves about one point of grid sensitivity (e.g. if motion detection occured with a grid sensitivity starting from 9, when enabling this property it occurs only with a grid sensitivity starting from 8).
