Abstract

A video surveillance system includes a video camera, a display device, and a control apparatus. The video camera is used for capturing video images. The display device is used for displaying the video images. The control apparatus is used for controlling the video camera. The control apparatus includes a detector and a processing module. The detector is used for detecting an event and generating an event detected signal corresponding to the event. The processing module is used for enabling the video camera based on the event detected signal.

Claims

1. A video surveillance system, comprising:

a video camera for capturing video images;

a display device for displaying the video images; and

a control apparatus for controlling the video camera, wherein the control apparatus comprising;

a detector for detecting an event and generating an event detected signal corresponding to the event; and

a processing module for enabling the video camera according to the event detected signal.

2. The video surveillance system as claimed in claim 1, further comprising a storage device for storing the video images.

3. The video surveillance system as claimed in claim 1, further comprising an indicator for indicating whether the video camera is capturing video images.

4. The video surveillance system as claimed in claim 1, wherein the detector is an infrared sensor.

5. The video surveillance system as claimed in claim 1, wherein the control apparatus comprises an amplifier for amplifying the event detected signal.

6. The video surveillance system as claimed in claim 5, wherein the processing module comprises a memory unit for storing a predetermined value.

7. The video surveillance system as claimed in claim 6, wherein the processing module further comprises a comparing unit for comparing the predetermined value with the amplified event detected signal.

8. The video surveillance system as claimed in claim 7, wherein the processing module further comprises a switching unit for enabling and disabling the video camera based on a comparison result of the comparing unit.

9. The video surveillance system as claimed in claim 8, wherein the switching unit enables the video camera if the amplified event detected signal is larger than the predetermined value.

10. The video surveillance system as claimed in claim 8, wherein the switching unit disables the video camera if the amplified event detected signal is smaller than the predetermined value.

11. The video surveillance system as claimed in claim 1, wherein the processing module comprises a graphic processing unit for compressing the video images.

12. A control apparatus for controlling a video camera, comprising:

a detector for detecting an event and generating an event detected signal corresponding to the event; and

a processing module for enabling the video camera according to the event detected signal, wherein the processing module comprising;

a memory unit for storing a predetermined value;

a comparing unit for comparing the predetermined value with the event detected signal; and

a switching unit for enabling the video camera based on a comparison result of the comparing unit.

13. The control apparatus as claimed in claim 12, wherein the switching unit enables the video camera if the event detected signal is larger than the predetermined value.

14. The control apparatus as claimed in claim 12, wherein the switching unit disables the video camera if the event detected signal is smaller than the predetermined value.

15. The control apparatus as claimed in claim 12, wherein the processing module comprises a graphic processing unit for compressing the video images.

16. The control apparatus as claimed in claim 12, further comprises an amplifier for amplifying the event detected signal.

17. A method for controlling a video surveillance system, comprising:

generating an event detected signal in response to an event;

comparing the event detected signal with a predetermined value and generating a comparison result; and

enabling a video camera if the event detected signal is larger than the predetermined value.

18. The method as claimed in claim 17, further comprising:

disabling the video camera if the event detected signal is smaller than the predetermined value.

19. The method as claimed in claim 17, further comprising:

amplifying the event detected signal.

20. The method as claimed in claim 17, further comprising:

compressing and storing the video images.
