Abstract

A television or film camera is attached to an overhead ceiling structure, etc., on a support member which is capable of rotating or panning the camera about a vertical axis and tilting the camera about a horizontal axis. The camera and its movable support structure are enclosed in a stationary housing having a base portion adjacent the ceiling structure and a transparent dome suspended below the base portion. The dome is coated on its inside concave surface with a fine layer of chromium which renders the dome transparent from its relatively dark inside area and opaque or reflective from the lighter area outside the housing. The camera is thus able to assume an infinite number of positions and focus on various objects in its vicinity about the housing without visual detection from without the housing.

Claims

1. In combination, a camera, support means connected to said camera, a housing enclosing said camera, said housing comprising a generally hemispherical transparent cover coated generally uniformly with chromium or the like of a density sufficient to reflect a portion of the light from outside said housing away from said housing whereby the cover is transparent from its darker side and generally reflective from its lighter side so that said camera is usually substantially invisible from outside said housing.

2. The combination of claim 1 and wherein the camera support means is constructed to rotate said camera about a vertical axis.

3. The combination of claim 1 and wherein the camera support means is constructed to rotate said camera about a vertical axis and to tilt said camera about a horizontal axis.

4. The combination of claim 1 and wherein the housing includes an opaque base portion surrounding at least a major portion of the camera support means.

5. The combination of claim 1 and wherein said generally hemispherical transparent cover is hingedly connected to said base portion, whereby when the cover is swung open, the camera and support means are physically exposed.

6. The combination of claim 1 and wherein the reflective coating is of sufficient density to attenuate the light transmitted through the transparent cover at least 50 percent.

7. The combination of claim 1 and wherein said camera is a television camera, and further including a television monitor capable of receiving a signal from said camera and arranged to display the image received by said camera.

8. A housing for concealing a camera or the like comprising hollow base defining a circular opening and a generally hemispherical transparent cover of a radius less than the height of said base, the circular edge portion of said cover including an outwardly extending flange member sized and shaped to engage said base at said circular opening either with said cover extending inwardly through said circular opening of the base for storage or extending outwardly from said circular opening of the base for confining a camera or the like in the enclosure defined by the base and cover.

9. The housing of claim 8 wherein the concave surface of said generally hemispherical transparent cover is coated with a light reflective substance wherein the cover is transparent from its darker side and generally reflective from its lighter side.

10. The housing of claim 8 and further including hinge means for pivotally connecting said cover to said base.

11. The housing of claim 8 and further including a camera, support means situated in the base of said housing and connected to said camera and arranged to rotate said camera about a first axis parallel to the longitudinal axis of said base and to pivot said camera about an axis approximately normal to said first axis and approximately at the center of curvature of said hemispherical transparent cover, said support means being constructed and arranged to maintain the lens of said camera oriented toward and adjacent said transparent cover, whereby said camera and its support means substantially eclipse any back light.

12. In combination, a camera, support means connected to said camera constructed and arranged to rotate said camera about a vertical axis and to tilt said camera about a horizontal axis, a stationary housing enclosing said camera comprising an opaque base portion surrounding at least a major portion of said support means and defining a downwardly facing opening, a generally hemispherical transparent cover removably connected to said base portion adjacent the downwardly facing opening whereby said camera is movable to an infinite number of positions with its lens facing said transparent cover, said transparent cover being coated generally uniformly with chromium or the like of a thickness sufficient to reflect a portion of the light from outside said housing away from said housing so that said camera is usually substantially invisible from outside said housing.

13. The combination of claim 12 and further including means for remotely controlling the camera support means for rotating the camera about a vertical axis within said housing.

14. The combination of claim 12 and further including remote control means connected to said support means for pivoting said camera about a horizontal axis.

15. The combination of claim 12 and wherein said camera is a television camera, and further including a television monitor capable of receiving the signal of said camera and arranged to display the image received by said camera.

16. A housing for concealing a television camera or the like comprising an opaque hollow frusto conical base for mounting on a supporting object, and a generally hemispherical transparent cover of a radius less than the height of said base, the circular edge portion of said cover being sized and shaped to engage the smaller end of said generally frusto conical base with the convex portion of said cover extending either inwardly of said base a distance less than the height of said base for storage purposes or the like or outwardly of said base for confining a television camera or the like in said housing, said cover being coated with chromium or the like of a generally uniform density to reflect a portion of the light from outside said housing away from said housing so that the camera inside said housing is normally invisible from outside said housing.

17. In combination, a camera, support means connected to said camera, a housing enclosing said camera, said housing comprising a base portion of hollow frusto-conical configuration with an annular edge portion about its smaller diameter opening, a generally hemispherical transparent cover with an annular edge normally positioned adjacent the smaller diameter opening of said base portion, said hemispherical cover being coated generally uniformly with chromium or the like of a density sufficient to reflect a portion of the light from outside said housing away from said housing whereby the cover is transparent from its darker side and is generally reflective from its lighter side so that said camera is usually substantially invisible from outside the housing.
