Abstract

In a video surveillance apparatus having

a) a dome camera (14) with a housing (15) and a first dome (16) in which a video camera with a lens (18) is disposed which is adjustable about a vertical axis of rotation (A-A) and a horizontal swiveling axis, having

b) a plate system (6) with electrical components and a mounting for the dome camera (14), a first plane of separation (E1-E1) being disposed between the plate system (6) and the dome camera (14), and having

c) a protective housing (19) which surrounds the plate system (6) and the dome camera (14) and which has a second dome (21) near the first dome (16),

to improve the accessibility of electrical parts and components, retrofitting, the making and breaking of mechanical and electrical connections such as screw, plug and soldered connections, the design is configured such that

d) the plate system (6) is disposed on the bottom of a supporting flange (3) and underneath its outer margin, and that

e) the second dome (21) is prolonged upward in the direction of the axis of rotation (A-A) by a housing jacket (20) which surrounds the plate system (6) and has an upper margin which is releasably connected to the supporting flange (3), a second plane of separation (E2-E2) being formed which lies above the first plane of separation.

Claims

1. Video surveillance apparatus comprising:

a dome camera with a housing and an at least partially radiation-permeable first dome in which a video camera with a lens is disposed whose optical axis is adjustable about a vertical axis of rotation and a horizontal swivel axis, with

a plate system with electrical components and a mount for the dome camera a first plane of separation being disposed between the plate system and the dome camera and with

a protective housing which surrounds the plate system and the dome camera and which has a second radiation-permeable dome near the first dome wherein

the plate system is disposed on the bottom of a supporting flange and at least substantially below its outer margin,

the second dome is prolonged in the direction of the axis of rotation upward through a housing jacket which surrounds the plate system and has an upper margin which is releasably fastened to the supporting flange, a second plane of separation being formed at the junction point, and lies above the first plane of separation.

2. Video surveillance apparatus according to

claim 1

, wherein in the housing a rotary drive and a swiveling drive are disposed for the remote-controlled movement of the optical axis of the lens.

3. Video surveillance apparatus according to

claim 1

, wherein the supporting flange has a coaxial surface onto which the upper margin of the housing jacket can be placed.

4. Video surveillance apparatus according to

claim 1

, wherein the supporting flange is substantially discoidal in form and connects a mounting pipe to the housing jacket of the protective housing.

5. Video surveillance apparatus according to

claim 1

, wherein on the bottom of the supporting flange at least one supporting plate is fastened through at least one set of spacers and to it the dome camera is fastened, the first plane of separation being disposed between the supporting plate and the dome camera.

6. Video surveillance apparatus according to

claim 5

, wherein between the supporting flange and the supporting plate an intermediate plate is disposed, the intermediate plate being connected through a first set of spacers to the supporting flange and the supporting plate being connected through a second set of spacers to the intermediate plate.

7. Video surveillance apparatus according to

claim 5

, wherein the plate system is fastened removably as a component group to the supporting flange.

8. Video surveillance apparatus according to

claim 6

, wherein the plate system is fastened removably as a component group to the supporting flange.

9. Video surveillance apparatus according to

claim 7

, wherein the plate system is fastened by means of keyhole-shaped openings to the spacers of the supporting flange.

10. Video surveillance apparatus according to

claim 8

, wherein the plate system is fastened by means of keyhole-shaped openings to the spacers of the supporting flange.

11. Video surveillance apparatus according to

claim 6

, wherein a heating element is fastened to the supporting flange and a blower for circulating the heated internal atmosphere of the protective housing is fastened to the intermediate plate.

12. Video surveillance apparatus according to

claim 5

, wherein a heating element is fastened to the supporting flange and a blower for circulating the heated internal atmosphere of the protective housing is fastened to the supporting plate.

13. Video surveillance apparatus according to

claim 1

, wherein the housing jacket has a ring on its bottom, and that the second dome has an outwardly bent margin which is fixed against the ring by a snap ring with the interposition of a gasket.

14. Video surveillance apparatus according to

claim 1

, wherein the housing jacket is surrounded by an additional jacket.

15. Video surveillance apparatus according to

claim 1

, wherein above the supporting flange an upwardly removable protective roof is disposed, whose outer margin overlaps the upper margin of the protective housing.

16. Video surveillance apparatus according to

claim 1

, wherein the housing jacket of the protective housing is configured as a hollow cylinder.

17. Video surveillance apparatus according to

claim 14

, wherein the length of the housing jacket amounts to at least 0.5 times its outside diameter.

18. Video surveillance apparatus according to

claim 15

, wherein the length of the housing jacket is at least 0.8 times its outside diameter.

19. Video surveillance apparatus according to

claim 1

, wherein the outer dome consists of a partially spherical shell from whose margin a hollow cylindrical prolongation of the same diameter as that of the margin extends toward the housing jacket.

20. Video surveillance apparatus according to

claim 17

, wherein the outer dome consists of a hemispherical shell and of a hollow cylindrical prolongation of the same diameter.
