Abstract

A camera module is described that incorporates a rear portion, a front portion, a camera, a wireless antenna, and a wireless transceiver. The rear portion has a substantially circular cross section with a first diameter and includes a front surface and a rear surface. The front portion has a substantially cylindrical body with a second diameter that is smaller than the first diameter and extends from the front surface of the rear portion of the camera module. The front portion also includes a front surface that is arranged opposite the rear surface of the rear portion of the camera module. The camera is configured to capture video data and is exposed at the front surface of the front portion of the camera module. The wireless antenna is arranged within the camera module. The wireless transceiver is coupled to the wireless antenna and the camera and is configured to communicate video data captured by the camera to a wireless network.

Claims

1. A camera module, comprising:

a rear portion having a substantially circular cross section, the circular cross section of the rear portion having a first diameter, the rear portion including a front surface and a rear surface;

a front portion having a substantially cylindrical body, the cylindrical body having a second diameter that is smaller than the first diameter, the cylindrical body extending from the front surface of the rear portion of the camera module by a length that is substantially larger than a thickness of the rear portion to allow the camera module to be held at the front portion, the front portion including a front surface that is arranged opposite the rear surface of the rear portion of the camera module;

a camera configured to capture video data, the camera being exposed at the front surface of the front portion of the camera module;

a wireless antenna arranged within the camera module; and

a wireless transceiver coupled to the wireless antenna and the camera, the wireless transceiver being configured to communicate video data captured by the camera to a wireless network.

2. The camera module of claim 1, wherein the front surface of the front portion of the camera module has a convex shape with respect to the rear portion of the camera module.

3. The camera module of claim 2, further comprising one or more infrared light emitting diodes (IR LEDs), wherein the one or more IR LEDs are enclosed in the camera module and located behind the front surface of the front portion of the camera module, and the front portion of the camera module includes IR-transparent material configured to conceal the one or more IR LEDs.

4. The camera module of claim 3, further comprising a status light arranged at the front surface of the front portion of the camera module, the status light being configured to provide visual indications regarding a status of the camera module.

5. The camera module of claim 1, wherein the rear portion includes beveled edges around its periphery.

6. The camera module of claim 5, wherein the edges are beveled such that the cross section of the rear portion increases from the rear surface of the rear portion to a midpoint between the rear surface and the front surface of the rear portion, and decreases from the midpoint to the front surface of the rear portion.

7. The camera module of claim 6, wherein the second diameter is smaller than the diameter of any circular cross section of the rear portion.

8. The camera module of claim 7, further comprising a speaker arranged at the rear surface of the rear portion of the camera module, the speaker being configured to output audible sounds.

9. The camera module of claim 7, further comprising a reset pin arranged at the rear surface of the rear portion of the camera module.

10. The camera module of claim 7, further comprising an electromechanical port arranged at the rear portion of the camera module.

11. A system, comprising:

a camera module, including;

a rear portion having a substantially circular cross section, the circular cross section of the rear portion having a first diameter, the rear portion including a front surface and a rear surface;

a front portion having a substantially cylindrical body, the cylindrical body having a second diameter that is smaller than the first diameter, the cylindrical body extending from the front surface of the rear portion of the camera module by a length that is substantially larger than a thickness of the rear portion to allow the camera module to be held at the front portion, the front portion including a front surface that is arranged opposite the rear surface of the rear portion of the camera module;

a camera configured to capture video data, the camera being exposed at the front surface of the front portion of the camera module;

a wireless antenna arranged within the camera module; and

a wireless transceiver coupled to the wireless antenna and the camera, the wireless transceiver being configured to communicate video data captured by the camera to a wireless network.

12. The system of claim 11, further comprising:

an arm configured to receive and hold the camera module;

a base; and

a joint mechanically coupling the arm to the base, the joint being configured to provide at least one degree of motion for the arm and the camera module held thereby with respect to the base.

13. The system of claim 12, wherein the arm includes a cutout having a diameter approximately equal to the second diameter.

14. The system of claim 13, wherein the arm has a first width at the cutout and a second width at the joint, the first width being greater than the second width.

15. The system of claim 14, wherein the arm includes side surfaces that are tapered from the cutout to the joint.

16. The system of claim 15, wherein the arm is substantially flat.

17. The system of claim 12, wherein the base includes a top surface and a bottom surface, the bottom surface is substantially planar, and the top surface has a convex shape with respect to the bottom surface.

18. The system of claim 12, wherein the arm includes a front surface facing in the same direction as the front surface of the front portion of the camera module, and a rear surface facing in the same direction as the rear surface of the rear portion of the camera module.

19. The system of claim 12, wherein the joint is configured to provide only one degree of motion for the arm and the camera module held thereby with respect to the base, wherein the one degree of motion enables the front surface of the of the base to rotate towards the top surface of the base in a first direction and enables the rear surface of the base to rotate towards the top surface of the base in a section direction opposite to the first direction.

20. The system of claim 12, further comprising a wall mount having mounting screw holes, the wall mount being configured to mechanically receive the base.
