hi when in ir mode / night vision with external ipcam i am getting lots of what looks like dust particles blowing past the lense in all kinds of directions the best way i can describe it would be imagine a windy night and throwing handfuls of dust in the cams close field of vision the particles show up bright and as if "dancing" although i am sure it is not dust i cant figure out what might be the cause of this anyone know anything about this phenomenon? any help much appreciated thanks
