Abstract

A protecting system is to protect a camera. When the protecting system detects heat which reaches a predetermined value, the protecting system outputs a first signal. The protecting system further magnifies the first signal to output a second signal. A controlling circuit starts a buzzer when the controlling circuit receives the second signal.

Claims

1. A protecting system for protecting a camera, the protecting system comprising:

an infrared sensor to sense heat, wherein the infrared sensor outputs a first signal upon the condition that the infrared sensor detects heat which reaches a predetermined value;

a magnifying circuit to magnify the first signal and output a second signal;

an annunciator; and

a controlling circuit to receive the second signal to start the annunciator.

2. The protecting system of claim 1, wherein the controlling circuit comprises a switch connected between the annunciator and a power supply.

3. The protecting system of claim 1, wherein the magnifying circuit comprises an amplifier.

4. The protecting system of claim 1, wherein the infrared sensor is mounted on a surface of the camera.

5. The protecting system of claim 1, wherein the annunciator is mounted on a surface of the camera.

6. The protecting system of claim 1, wherein the magnifying circuit is located inside the camera.

7. The protecting system of claim 1, wherein the controlling circuit is located inside the camera.

8. A protecting method for protecting a camera, comprising:

detecting heat by an infrared sensor;

determining whether the infrared sensor detects heat which reaches a predetermined value;

outputting a first signal from the infrared sensor upon the condition that the infrared sensor detects heat which reaches a predetermined value;

magnifying the first signal to obtain a second signal by a magnifying circuit; and

starting an annunciator by a controlling circuit upon the condition that the controlling circuit receives the second signal.

9. The protecting method of claim 8, wherein upon the condition that the infrared sensor does not detect heat which reaches a predetermined value, the infrared sensor continues to detect heat.

10. The protecting method of claim 8, wherein the controlling circuit comprises a switch connected to the buzzer and a power supply.

11. The protecting method of claim 8, wherein the magnifying circuit comprises an amplifier.

12. The protecting method of claim 8, wherein the infrared sensor is mounted on a surface of the camera.

13. The protecting method of claim 8, wherein the annunciator is mounted on a surface of the camera.

14. The protecting method of claim 8, wherein the magnifying circuit is located inside the camera.

15. The protecting method of claim 8, wherein the controlling circuit is located inside the camera.
