Abstract
A visibility-impairing security device is disclosed for producing a gathering of air-suspended light-obscuring matter to obscure vision. The device comprises a body comprising an emission unit receiving portion for holding an emission unit having an outlet for emitting the matter; an opening for the passing therethrough of the matter from the outlet; and a door for closing the opening. The door is configured to move between a closed position in which the opening is covered and an open position in which the opening is at least partially open, thus allowing for the passing therethrough of the matter from the outlet when the door is in the open position.
