The camera is mounted on a slide, which crosses access to the understage area at high speed downstage. Previously, flashing lights had warned of the approaching slide camera. The idea was to optimise this concept, to increase the safety of the stage technicians and exclude manipulation. Today, the danger zone is secured by Pilz’s Type 3 light curtains PSENopt II with hand resolution. Should anyone reach or run into the first pair of light curtains while the camera is moving, the camera slide is stopped immediately. Only once the person has passed through the second light curtain is the zone reset automatically and the slide camera enabled. With this adaptation, the Ehrlich Brothers can happily concentrate on the dramatic composition of their show – for the perfect illusion. http://www.pilz.com
