I have a camera in a staircase which always triggers motion detection when the staircase lighting turns on and off. Back when using zone minder I did solve that by using a "negative" zone. When pixel changed there, it did ignore motion in the other zones of the image. By using a small area up the wall that nobody would reach, I got perfect results. Hence it would be great if NX Witness could implement the same. On the motion page, one could introduce a -1 sensitivity, which would then show the same behaviour.
