Abstract

Claims (43)

1. A surveillance camera, comprising:

an imaging assembly;

a dome cover comprising a transparent portion and formed to surround the imaging unit assembly;

a shield configured to move along a surface of the dome cover;

a shield driver configured to control the shield; and

a sensor configured to sense a value corresponding to at least one of whether an object is approaching the surveillance camera, whether the surveillance camera is falling, whether an impact is exerted on the dome cover, and whether a voice signal is input from outside of the surveillance camera,

wherein the sensed value is compared with a preset value, and

wherein the shield driver is further configured to control the shield to shield at least a portion of the dome cover based on a result of the comparing.

2. The surveillance camera of claim 1 , wherein the shield driver comprises:

a rack gear connected with the shield;

a pinion gear engaged with the rack gear and configured to rotate; and

a driver connected with the pinion gear and configured to rotate the pinion gear.

3. The surveillance camera of claim 1 , wherein the shield driver is further configured to control the shield to shield at least a portion of the dome cover in response to the sensed value being equal to or greater than the preset value.

4. The surveillance camera of claim 1 , further comprising an alarm configured to output an alarm to the outside based on the sensed value.

5. The surveillance camera of claim 1 , wherein the sensor comprises a laser sensor configured to sense whether the object is approaching the surveillance camera.

6. The surveillance camera of claim 1 , wherein the shield is formed of an elastic material.

7. The surveillance camera of claim 1 , wherein the shield is formed in a ring shape.

8. The surveillance camera of claim 1 , further comprising a controller configured to store the preset value, compare the sensed value with the preset value, and control the shield driver based on the result of the comparing.

9. A surveillance camera, comprising:

an imaging assembly;

a dome cover comprising a transparent portion and formed to surround the imaging assembly;

a shield configured to move along a surface of the dome cover; and

a shield driver configured to control the shield to shield at least a portion of the dome cover based on a result of comparing data acquired by the imaging assembly with preset data,

wherein the preset data comprises at least one of an object approaching the camera, the camera failing, an impact exerted on the dome cover, and a received voice command.

10. The surveillance camera of claim 9 , wherein the shield is formed of an elastic material.

11. The surveillance camera of claim 9 , wherein the shield is formed in a ring shape.

12. The surveillance camera of claim 9 , further comprising a controller configured to store the preset data, compare the data acquired by the imaging assembly with the preset data, and control the shield driver based on the result of the comparing.

13. A method of protecting a surveillance camera, the method comprising:

generating data by at performing at least one of:

photographing an area in which the surveillance camera is disposed; and

sensing at least one of whether an object is approaching the surveillance camera, whether the surveillance camera is falling, whether an impact is exerted on a dome cover of the surveillance camera, and whether a voice signal input from the area in which the surveillance camera is disposed;

comparing the generated data with preset data; and

in response to the generated data being equal to or greater than the preset data, operating a shield driver to protect the dome cover with a shield.

14. The method of claim 13 , wherein the generated data selected from the group consisting of an acquired image, an acquired video, an acceleration value, an angular speed, a speed value, an impact value, and a voice signal.

15. A camera comprising:

a camera module;

a shield configured to protect the camera module; and

a controller configured to control the shield to protect the camera module in response to determining that a predetermined event occurs;

a dome cover comprising a transparent portion and formed to surround the camera module; and

a shield driver configured to move the shield based on a signal received from the controller,

wherein the predetermined event comprises at least one of an object approaching the camera, the camera falling, an impact exerted on the dome cover, and a received voice command.

16. The camera of claim 15 , wherein the shield is configured to move along the dome cover.

17. The camera of claim 16 , where the shield is formed of an elastic material.
