A pan-tilt mechanism for a video conferencing camera may be provided. The pan-tilt mechanism may comprise a base, a bracket, a tilt motor, and a pan motor. The tilt motor may be fixed to the base and may be configured to cause the bracket to tilt along a horizontal axis. The pan motor may be fixed to the base and may be configured to cause the bracket to pan about a vertical axis without affecting the tilt of the bracket.

1. An apparatus comprising: a tilt motor fixed to a base and configured to cause a bracket to tilt along a horizontal axis; anda pan motor fixed to the base and configured to cause the bracket to pan about a vertical axis and to cause a bracket to tilt along the horizontal axis. 2. The apparatus of
1. An apparatus comprising: a tilt motor fixed to a base and configured to cause a bracket to tilt along a horizontal axis; anda pan motor fixed to the base and configured to cause the bracket to pan about a vertical axis and to cause a bracket to tilt along the horizontal axis. 2. The apparatus of claim 1, further comprising: a lift nut operatively fixed to the tilt motor; anda tilt arm operatively fixed to the lift nut, wherein movement of the lift nut causes the lift arm to apply a force to the bracket, the force operative to cause the bracket to tilt along the horizontal axis. 3. The apparatus of claim 1, further comprising a lift nut operatively fixed to the tilt motor and the bracket, wherein movement of the lift nut causes a force to be applied to the bracket, the force operative to cause the bracket to tilt along the horizontal axis. 4. The apparatus of claim 1, further comprising a pan gear operatively connected to the pan motor, wherein rotation of the pan gear causes the bracket to rotate about the vertical axis. 5. The apparatus of claim 1, further comprising a lens housing connected to the bracket. 6. The apparatus of claim 1, further comprising a camera connected to the bracket. 7. An apparatus comprising: a tilt motor fixed to a base;a pan motor fixed to the base;a bracket operatively connected to the tilt motor and the pan motor;a memory; anda processor in electrical communication with the tilt motor and the pan motor, the processor configured to: output a first signal to the tilt motor, the first signal configured to cause the bracket to tilt about a horizontal axis to a tilt angle, andoutput a second signal to the pan motor and a third signal to the tilt motor, the second signal and the third signal together being configured to cause the bracket to pan about a vertical axis and to simultaneously move a lift arm to maintain the tilt angle of the bracket. 8. The apparatus of claim 7, wherein the processor operative to output the first signal and output the second signal comprises, the processor operative to output the first signal and the second signal simultaneously. 9. The apparatus of claim 7, wherein the processor operative to output the first signal and output the second signal comprises, the processor operative to synchronize a tilt motor speed with a pan motor speed such that the tilt angle remains constant. 10. The apparatus of claim 7, further comprising a camera. 11. The apparatus of claim 10, further comprising the processor operative to: receive a video signal from the camera, andoutput the video signal to a display. 12. An apparatus comprising: a spur gear;a tilt body configured to rotate about a vertical axis passing through the spur gear, the vertical axis being substantially perpendicular to the spur gear;a bracket connected to the tilt body and being configured to tilt about a horizontal axis being substantially perpendicular to the vertical axis;a tilt motor configured to, when the tilt body is held stationary, rotate the spur gear about the vertical axis causing the bracket to tilt about the horizontal axis; anda pan motor configured to, when the spur gear is held stationary, rotate the tilt body about the vertical axis and simultaneously causing the bracket to tilt about the horizontal axis, the tilt motor and the pan motor being fixed to a base. 13. The apparatus of claim 12, further comprising a lift nut operatively fixed to the tilt motor and the bracket, wherein movement of the lift nut causes a force to be applied to the bracket, the force operative to cause the bracket to tilt along the horizontal axis. 14. The apparatus of claim 12, the tilt body further comprising a geared section operatively connected to the pan motor. 15. The apparatus of claim 12, further comprising a lens housing connected to the bracket. 16. The apparatus of claim 12, further comprising a camera connected to the bracket. 17. A method comprising: rotating, when a tilt body is held stationary, a spur gear about a vertical axis causing a bracket connected to the tilt body to tilt about a horizontal axis, the vertical axis being substantially perpendicular to the horizontal axis, the vertical axis being substantially perpendicular to the spur gear; androtating, when the spur gear is held stationary, the tilt body about the vertical axis simultaneously causing the bracket to tilt about the horizontal axis. 18. The method of claim 17, wherein rotating the spur gear comprises rotating the spur gear using a tilt motor. 19. The method of claim 17, wherein rotating the tilt body comprises rotating the tilt body using a pan motor. 20. The method of claim 17, wherein rotating the spur gear comprises rotating the spur gear using a tilt motor and wherein rotating the tilt body comprises rotating the tilt body using a pan motor, the tilt motor and the pan motor being fixed to a base.
