said lens means and said pickup means are pivotal relative to a first direction.

4. A surveillance assembly in accordance with claim 3 wherein:

said first direction is the horizontal direction.

5. A surveillance assembly in accordance with claim 3 wherein:

said mounting means mounts said lens means, said pickup means and said camera body means so as to be rotatable about a second direction.

6. A surveillance assembly in accordance with claim 5 wherein:

said first direction is the horizontal direction and said second direction is the vertical direction.

7. A surveillance assembly in accordance with claim 5 wherein:

said mounting means comprises;

a first plate mounted to said housing so as to be rotatable about said second direction; and

second plate mounted to said first plate so as to be pivotable about said first direction;

said camera body means is mounted to said first plate;

and said lens means and pickup means are mounted to said second plate.

8. A surveillance assembly in accordance with claim 7 wherein:

said second plate has an aperture therethrough;

and said lens means and pickup means are mounted to said second plate so as to extend through said aperture.

9. A surveillance assembly in accordance with claim 7 wherein:

said first plate includes first and second arms extending in a direction outwardly of said housing;

and second plate is pivotally supported between said arms.

10. A surveillance assembly in accordance with claim 9 wherein:

said camera body means is mounted to said first plate in spaced relationship to said arms.

11. A surveillance assembly in accordance with claim 10 wherein:

the longest dimension of said camera body means parallels the direction between said arms.

12. A surveillance assembly in accordance with claim 1 further comprising:

cable means for connecting said pickup means to said camera body.

13. A surveillance assembly in accordance with claim 1 further comprising:

a means for covering said housing to enclose said viewing, camera and mounting means and for allowing said viewing means to view outward of said housing.

14. A surveillance assembly in accordance with claim 13 wherein:

said mounting means pivotally mounts said viewing means to said housing; and

said cover means has a region which is at least partially transmissive to light and through portions of which said viewing means views as said viewing means is positioned by said pivoting.

15. A surveillance assembly in accordance with claim 14 further comprising:

means for blocking the transmission of light through portions of said region other than the portion through which said viewing means is positioned to view.

16. A surveillance assembly in accordance with claim 15 wherein:

the portions of said region for which the transmission of light is blocked are those below the portion through which said viewing means is positioned to view.

17. A surveillance assembly in accordance with claim 16 wherein:

the portions of said region for which the transmission of light is blocked are substantially all portions of said region below the portion through which said viewing means is positioned to view.

18. A surveillance assembly in accordance with claim 15 wherein:

said cover means comprises a dome-like shroud, said dome-like shroud having a sector forming said region;

said blocking means comprises a shutter;

and said mounting means mounts said shutter to move through and block said sector in response to pivoting of said viewing means.

33. A surveillance assembly in accordance with claim 2 wherein:

the length of the longest dimension of said camera body means is transverse to said viewing direction.

19. A surveillance assembly comprising:

a housing;

means for viewing outward of said housing and producing an image;

camera means for receiving the image produced by said viewing means;

mounting means for mounting said viewing means and camera means to said housing;

means for covering said housing to enclose at least said viewing means and camera means, said cover means having a region which is at least partially transmissive to light and through portions of which said viewing means views outward of said housing;

and means for blocking the transmission of light through portions of said region other than the portion through which said viewing means is positioned to view.

20. A surveillance assembly in accordance with claim 19 wherein:

the portions of said region for which the transmission of light is blocked are those below the portion through which said viewing means is positioned to view.

21. A surveillance assembly in accordance with claim 20 wherein:

the portions of said region for which the transmission of light is blocked are substantially all portions of said region below the portion through which said viewing means is positioned to view.

22. A surveillance assembly in accordance with claim 19 wherein:

said mounting means pivotally mounts said viewing means to said housing;

said cover means comprises a dome-like shroud, said dome-like shroud having a sector forming said region;

said blocking means comprises a shutter;

and said mounting means mounts said shutter to move through and block said sector in response to pivoting of said viewing means.

23. A surveillance assembly in accordance with claim 22 wherein:

said mounting means pivotally mounts said shutter to said housing so as to cause said shutter to follow the contour of said shroud adjacent to said sector.

24. A surveillance system in accordance with claim 23 wherein:

the pivot positions of said viewing means and said shutter are offset.

25. A surveillance assembly in accordance with claim 24 wherein:

said mounting means comprises a first plate pivotal about a first direction and mounted at a first point of said mounting means;

said viewing means is mounted to said first plate;

and said shutter means comprises;

an arm having one end pivotally mounted to said mounting means at a second point and being responsive to said first plate; and

a shutter mounted to a second end of said arm so as to be adjacent to said shroud.

26. A surveillance assembly in accordance with claim 25 wherein:

said arm includes a slot;

and said mounting means further includes a drive bar connected to said first plate and passing through said slot.
