ABSTRACT:
The apparatus for optical monitoring facility, wherein two circular elements are swivel-mounted at a support section. A television camera is fixed inside the first circular element, whereas the second circular element carries two dummy lenses. The apparatus is installed in a cover by which only the camera lens and the dummy lenses can be seen from the outside. The first circular element can be swivelled by a swivel motor, whereas the second circular element is swivelled in the same way by means of cables. The apparatus can be rotated around its vertically fixing axis by a motor. A control equipment allows the adjustment of the camera lens and of the camera's position. The control equipment comprises a programmable microprocessor in which an observation's sequence can be stored. The apparatus is arranged in such a way that the observation through only one lens cannot be recognized from the outside world.
