Abstract

A security camera with an adjustable lens aiming mechanism comprises a dome base, an eyeball camera, a dome cover, and a fastener for fastening the dome cover to the dome base. The dome base comprises a camera seat. The eyeball camera comprises a lens and is movably seated on the camera seat. The dome cover covers the eyeball camera and comprises a bottom opening for engaging the dome base, a circular contact ring with a diameter smaller than the camera diameter and defining an opening through which the lens and a portion of the camera protrudes; and a fastener removably fastening the dome cover to the dome base such that when fully fastened, the contact ring makes contact with the camera and applies a sufficient pressure to fix the camera in place on the seat, and when partially or completely unfastened, the pressure is reduced such that the camera is movable on the seat and the lens is movable within the contact ring.

Claims

1. A security camera apparatus comprising:

(a) a base comprising a camera seat;

(b) an eyeball camera having a lens and being movably seated on the camera seat;

(c) a lens adjustment mechanism comprising a mount mountable to the base, a circular contact ring connected to the mount and having a diameter smaller than the camera diameter and defining an opening through which the lens and a portion of the camera protrudes; and

(d) a fastener removably fastening the lens adjustment mechanism to the base such that when fully fastened, the contact ring makes contact with the camera and applies a sufficient pressure to fix the camera in place on the seat, and when partially or completely unfastened, the pressure is reduced such that the camera is movable on the seat and the lens is movable within the contact ring.

2. An apparatus as claimed in claim 1 wherein the lens aiming mechanism comprises a cover which partially or wholly covers the eyeball camera, wherein the mount is a bottom opening in the cover, the contact ring is located at a front part of the cover, and the fastener is connected to the cover.

3. An apparatus as claimed in claim 2 wherein the cover is a dome cover and the base is a circular dome base.

4. An apparatus as claimed in claim 1 wherein the protruding portion of the camera comprises markings indicating an imaging plane of camera.

5. An apparatus as claimed in claim 4 wherein the markings are notches or protrusions on a rimmed opening encircling the lens and the indicated imaging plane is a horizontal plane.

6. An apparatus as claimed in claim 1 wherein the protruding portion of the camera comprises at least one finger grip.

7. An apparatus as claimed in claim 6 wherein the camera comprises multiple finger grips including one finger grip on a protruding portion of the camera located above the lens to indicate the top of an image taken by the camera.

8. An apparatus as claimed in claim 3 wherein the camera contains electro-optics and comprises a communications port and the apparatus further comprises a processing module containing processing circuitry and a communications cable coupling the processing module to the communications port on the camera, and the dome base further comprises a cable opening for routing the cable into the dome base.

9. An apparatus as claimed in claim 8 wherein the seat is located in a forward portion of the dome base and the camera and dome cover are sized such that a space is provided inside the dome cover to receive a sufficient length of communications cable to allow the camera to be rotated about a defined range on the seat.

10. An apparatus as claimed in claim 3 wherein the camera contains electro-optics and comprises a communications port and the dome base contains processing circuitry and comprises a communications port, and the apparatus further comprises a communications cable coupled to the communications ports of the camera and the dome base.

11. An apparatus as claimed in claim 10 wherein the seat is located in a forward portion of the dome base and the camera and dome cover are sized such that a space is provided inside the dome cover to receive a sufficient length of communications cable to allow the camera to be rotated about a defined range on the seat.

12. An apparatus as claimed in claim 1 wherein the camera contains electro-optics and processing circuitry.

13. An apparatus as claimed in claim 3 wherein the fastener comprises a locking tab on the dome cover and a tab opening on the dome base, and a screw and screw holes in the dome cove and dome base to fixedly receive the screw.

14. An apparatus as claimed in claim 1 wherein the eyeball camera comprises a weatherproof shell comprising a lens opening and a communications port that are both sealed to impede water from entering into the camera.

15. A method for adjusting a camera lens position on a security camera apparatus comprising:

a base comprising a camera seat;

an eyeball camera having a lens and being movably seated on the camera seat;

a lens adjustment mechanism comprising a mount mountable to the base, a circular contact ring connected to the mount and having a diameter smaller than the camera diameter and defining an opening through which the lens and a portion of the camera protrudes; and

a fastener removably fastening the lens adjustment mechanism to the base,

the method comprising;

(a) partially or completely unfastening the fastener from the base such that the camera is movable on the seat and the lens is moveable within the contact ring;

(b) moving the lens to a desired position; and

(b) fully fastening the fastener to the base such that the lens adjustment mechanism applies sufficient pressure to fix the camera in place on the seat.

16. A method as claimed in claim 15 wherein the protruding portion of the camera comprises markings indicating an imaging plane of camera, and the method further comprises moving the camera such that the markings are aligned with an imaging plane of interest.

17. A method as claimed in claim 16 wherein the markings are notches or protrusions on a rimmed opening encircling the lens and the indicated imaging plane is a horizontal plane, and the method further comprises moving the camera such that the indicated imaging plane is horizontally aligned with an external reference point.

18. A method as claimed in claim 15 wherein the protruding portion of the camera comprises at least one finger grip and the method comprises moving the lens by gripping the at least one finger grip.

19. A method as claimed in claim 18 wherein the camera comprises multiple finger grips including one finger grip on a protruding portion of the camera located above the lens to indicate the top of an image taken by the camera, and the method comprises moving the lens by gripping at least one of the finger grips such that the ginger grip located above the lens is vertically aligned with an external reference point.
