Abstract

A speed dome camera includes a stationary unit, a moving unit rotatably mounted to the stationary unit, and a wireless signal transmission module. The stationary unit includes a mounting base and a signal processing module supported at the mounting base. The moving unit includes an image capturer and a controller module operatively linked to the image capturer, wherein the image capturer is adapted for obtaining an image signal when the image capturer is rotating. The wireless signal transmission module is operatively linking the stationary unit with the moving unit for wirelessly transmitting the image signal from the image capturer to the signal processing module. Therefore, the high definition image signal is able to be wirelessly transmitted from the image capturer to the signal processing module while the moving unit is rotating at its maximum rotational speed of 400 degrees per second without affecting an image quality during wireless transmission.

Claims

1. A speed dome camera, comprising:

a stationary unit which comprises an outer casing, a mounting base received in said outer casing, and a signal processing module supported at said mounting base;

a moving unit, which is rotatably mounted to said stationary unit, comprising an image capturer and a controller module operatively linked to said image capturer, wherein said image capturer is adapted for obtaining an image signal when said image capturer is rotating with respect to said stationary unit; and

a wireless signal transmission module operatively linking said stationary unit with said moving unit for wirelessly transmitting said image signal from said image capturer to said signal processing module.

2. The speed dome camera, as recited in claim 1, wherein said wireless signal transmission module comprises a wireless transmitter supported at said moving unit to operatively link to said image capturer for receiving an image signal obtained by said image capturer and for converting said image signal into a wireless signal, and a wireless receiver mounted at said mounting base to operatively link to said signal processing module, wherein said wireless receiver receives said wireless signal from said wireless transmitter and reverts said wireless signal back to said image signal to be sent to said signal processing module.

3. The speed dome camera, as recited in claim 1, wherein said image signal is a non-compressed data format to be wirelessly transmitted from said image capturer to said signal processing module.

4. The speed dome camera, as recited in claim 2, wherein said image signal is a non-compressed data format to be wirelessly transmitted from said image capturer to said signal processing module.

5. The speed dome camera, as recited in claim 3, wherein said wireless signal transmission module has a maximum transfer rate of said image signal at 30 frames per second.

6. The speed dome camera, as recited in claim 4, wherein said wireless signal transmission module has a maximum transfer rate of said image signal at 30 frames per second.

7. The speed dome camera, as recited in claim 1, wherein said moving unit is rotatably mounted to said stationary unit through an electric slip ring that allows said moving unit being rotated 360°

in a high speed manner.

8. The speed dome camera, as recited in claim 4, wherein said moving unit is rotatably mounted to said stationary unit through an electric slip ring that allows said moving unit being rotated 360°

in a high speed manner.

9. The speed dome camera, as recited in claim 7, wherein said moving unit has a maximum rotational speed of 400 degrees per second without affecting an image quality during wireless transmission.

10. The speed dome camera, as recited in claim 7, wherein said moving unit has a maximum rotational speed of 400 degrees per second without affecting the image quality during wireless transmission.

11. The speed dome camera, as recited in claim 1, wherein said image capturer is a high definition camera adapted for obtaining a high definition video signal as said image signal.

12. The speed dome camera, as recited in claim 8, wherein said image capturer is a high definition camera adapted for obtaining a high definition video signal as said image signal.

13. A method for internally transmitting an image signal of a speed dome camera which comprises a moving unit, a stationary unit, and a wireless signal transmission module, comprising the steps of:

(a) obtaining said image signal by an image capturer of said moving unit, wherein said image capturer is rotated in a high speed manner while image capturing;

(b) wirelessly transmitting said image signal from a wireless transmitter to a wireless receiver of said wireless signal transmission module, wherein said wireless transmitter is built-in with said moving unit to operatively link to said image capturer while said wireless receiver is built-in with said stationary unit; and

(c) sending said image signal from said wireless receiver to a signal processing module of said stationary unit.

14. The method as recited in claim 13, before the step (b), further comprising a step of converting said image signal into a wireless signal through said wireless transmitter so as to wirelessly transmit said wireless signal to said wireless receiver.

15. The method as recited in claim 14, before the step (c), further comprising a step of reverting said wireless signal back to said image signal through said wireless receiver so as to send said image signal to said signal processing module.

16. The method as recited in claim 15 wherein, in the step (b), said image signal is a non-compressed data format to be wirelessly transmitted from said image capturer to said signal processing module through said wireless signal transmission module.

17. The method, as recited in claim 16, wherein said wireless signal transmission module has a maximum transfer rate of said image signal at 30 frames per second.

18. The method, as recited in claim 15, wherein said moving unit is rotatably mounted to said stationary unit through an electric slip ring that allows said moving unit being rotated 360°

in a high speed manner.

19. The method, as recited in claim 18, wherein said moving unit has a maximum rotational speed of 400 degrees per second without affecting an image quality during wireless transmission.

20. The method, as recited in claim 15, wherein said image capturer is a high definition camera adapted for obtaining a high definition video signal as said image signal.
