Abstract

The present invention relates to an enclosure for recess mounting of a camera or camera head in a recess of a surface, the enclosure comprising an attachment portion, a cable sealing portion being adapted to seal against an outer surface of the cable extending through the cable sealing portion, and a circumferential wall portion adapted to extend along a closed path in a circumferential direction and in a first direction extending from the attachment portion towards the cable sealing portion, wherein at least a portion of the circumferential wall portion is formed of a flexible and/or elastic material such that the cable sealing portion is movable relative the attachment portion. The present invention also relates to an arrangement for recess mounting of a camera or camera head in a recess of a surface.

First claim

What is claimed is:

1. An enclosure for recess mounting of a camera or camera head in a recess of a surface, the enclosure comprising:
an attachment portion, which when in use is fixed relative to said recess;
a cable sealing portion having an opening allowing a cable attached to said camera or camera head to extend through the opening and out of the enclosure, the cable sealing portion seals against an outer surface of the cable extending through the cable sealing portion; and
a circumferential wall portion that extends along a closed path in a circumferential direction and in a first direction extending from the attachment portion towards the cable sealing portion, which first direction in use of the enclosure extends into the recess,
wherein the enclosure in use provides a cavity inside which a camera or camera head located in the recess is positioned, and
wherein at least a portion of the circumferential wall portion is formed of a flexible and/or elastic material such that the cable sealing portion is movable relative the attachment portion.

2. An enclosure according to claim 1 , wherein the cable sealing portion is formed of a material which is flexible and/or elastic.

3. An enclosure according to claim 1 , wherein the cable sealing portion in a released state has an inner circumference being smaller than a circumference of the cable that extends out of the enclosure.

4. An enclosure according to claim 1 , wherein the cable sealing portion is formed of an elastomeric material having hardness between 20 and 60° Shore A.

5. An enclosure according to claim 1 , wherein the cable sealing portion is movable relative to the attachment portion in the first direction and along a plane parallel to a plane defined by a mouth of said recess.

6. An enclosure according to claim 1 , wherein said at least a portion of the circumferential wall portion being formed of a flexible and elastic material comprises a bellows portion shaped as a bellows tapered along a first direction extending from the attachment portion towards the cable sealing portion.

7. An enclosure according to claim 6 , wherein the bellows portion comprises a plurality of annular undulations each comprising a first major portion extending in said first direction and a second major portion extending in a second direction opposite said first direction, wherein the undulations are non-overlapping such that the bellows portion may be collapsed in said second direction.

8. An enclosure according to claim 1 , further comprising an annular cover sealing portion that forms a seal with an annular sealing portion of a cover such that the enclosure and said cover form a closed, sealed compartment that houses said camera or camera head.

9. An arrangement for recess mounting of a camera or camera head in a recess of a surface, the arrangement comprising:
a cover; and
an enclosure comprising:
an attachment portion, which when in use is fixed relative to said recess;
a cable sealing portion having an opening allowing a cable attached to said camera or camera head to extend through the opening and out of the enclosure, the cable sealing portion seals against an outer surface of the cable extending through the cable sealing portion; and
a circumferential wall portion that extends along a closed path in a circumferential direction and in a first direction extending from the attachment portion towards the cable sealing portion, which first direction in use of the enclosure is adapted to extend into the recess,
wherein the enclosure in use provides a cavity inside which a camera or camera head located in the recess is positioned, and

wherein at least a portion of the circumferential wall portion is formed of a flexible and/or elastic material such that the cable sealing portion is movable relative the attachment portion.

10. An arrangement according to claim 9 , wherein the cover comprises a window and an annular sealing portion that forms a seal with an annular sealing portion of the enclosure, whereby the cover and the enclosure form a closed, sealed compartment that houses said camera or camera head.

11. An arrangement according to claim 9 , further comprising a camera support that supports said camera or camera head.

12. An arrangement according to claim 11 , wherein the camera support is movable such that a camera or camera head supported by the camera support is movable to provide a pan movement, a tilt movement and/or a rotation movement.

13. An arrangement according to claim 9 , further comprising a camera, including optics, an image sensor and an image processor, supported by said camera support.

14. An arrangement according to claim 9 , further comprising a camera comprising a camera head including optics and an image sensor, a cable extending from the camera head to a main unit including an image processor, wherein the camera head is received in the sealed compartment, the cable extending through the cable sealing portion, and the main unit being located outside the sealed compartment.

15. An arrangement according to claim 9 , wherein the window is formed of a material allowing electromagnetic radiation within a wavelength interval detectable by an image sensor of the camera to pass from an outside into the camera such that the camera may provide a representation of the scene based on electromagnetic radiation within said wavelength interval.
