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.

Claims

1. Apparatus for optical monitoring, comprising:

camera means;

camera lens means;

dummy lenses means;

control equipment means;

fixing axis means;

the apparatus being rotatable around said fixing axis means, said camera means being optically connected with the camera lens means, said control equipment means regulating said camera and movement functions of the apparatus and said camera lens means and

dummy lens means being movable relative to each other.

2. The apparatus of claim 1, wherein said camera lens means can be swivelled in a first plane going through said fixing axis and said dummy lens means can be swivelled in a second plane going through said fixing axis and crossing said first plane in an approximately right angle.

3. The apparatus of claim 2, wherein at least one more dummy lens is mounted in each of said swivel-planes and can be swivelled there.

4. The apparatus of claim 2, wherein said camera means is fixed within said first circular element which can be swivelled around its axis, said dummy lens means being fixed at said second circular element which has a different radius from the first one, said swivel-axes of both circular elements crossing each other in an approximately right angle, said cover containing both circular elements in such a way that said camera lens means and said dummy lens means cannot be distinguished from the outside.

5. The apparatus of claim 4 having between said dummy lenses or between said dummy lens and said camera lens, wherein each pair is mounted on the same said circular element, an angle of 90°

to 135°

.

6. The apparatus of claim 4, wherein said first circular element is moved by said swivel-motor, said second circular element is mechanically coupled with said first circular element by means of said cables in order to carry out approximately the same movement as said first circular element.

7. The apparatus of claim 4, wherein both said circular elements are swivel-mounted at said support section.

8. The apparatus of claim 7, wherein said motor is mounted at said support section in order to rotate the apparatus around said fixing axis.

9. The apparatus of claim 8, wherein said motor has at least two rotation speeds.

10. The apparatus of claim 1, wherein said camera lens consists of a zoom-lens with variable focal length.

11. The apparatus of claim 1, wherein said camera means comprises a television camera.

12. The apparatus of claim 10, wherein said control equipment means regulates the rotation of the apparatus, the swivel-movement of said camera lens and said dummy lenses, and said variable focal length with said detail focusing of said zoom-lens.

13. The apparatus of claim 12, wherein said control equipment means contains said programmable microprocessor.

14. The use of the apparatus of claim 13 for the observation of a room, wherein a mirror is mounted at least at one place of the room, said control equipment means regulating said camera lens into the direction of said mirror and adjusting said focal length with said detail focusing of said zoom-lens in order to observe the room.

15. The apparatus of claim 10, wherein said camera zoom-lens contains adjustable rings for the continuous adjustment of said focal length and said detail focusing, whereby said adjustable rings can be rotated by said gear-drives of said electromotors.

16. The apparatus of claim 15, wherein said electromotors are fixed in said mounting which is removably attached to said adjustable rings of said camera lens.

17. The apparatus of claim 1, wherein said camera lens means is mechanically coupled to said dummy lens means.
