ABSTRACT:
A surveillance device consists of a video camera, a shutterless objective, a transmission optic element with an automatically controlled cat's eye shutter, and reflecting mirrors, for projecting an intermediate image generated by the objective into the video camera. The objective can swivel about both axes of the image, while a deflecting mirror is coupled to the objective in such a way that the intermediate image is always located in the same place.
