Blanking-out mask for a monitoring device like a camera has a lens enclosed by a telescopic tube, a lighting device outside the tube and/or a movement sensor

摘要

From outside a blanking-out mask (1) for a monitoring device is as good as invisible to an observer and consequently well camouflaged. Large powerful imaging lenses (3) can be inserted for a monitoring camera (2) because of the good camouflaging properties. A simple structure is produced because the blanking-out mask forms just a single piece. A surface pointing outwards has a flat shape.
