The dome cover part 130 is firmly fixed without moving and only the camera part 110 disposed inside the dome cover part 130 is operated in a horizontal direction or a vertical direction, thereby preventing dust and moisture generated from the outside. Alternatively, the camera unit 110 and the camera driver 120 in which the lens is disposed may be protected from impact. That is, the dome cover 130 is firmly fixed without being rotated, thereby effectively blocking moisture or dust. Therefore, the camera unit 110 is more securely protected from environmental hazards or environmental hazards.

In addition, the dome cover part 130 may include a camera material 110 disposed therein, which may be formed of a transparent material so that the predetermined area may be clearly photographed without distortion.

The infrared lamp unit 140 operates in the same direction as the direction in which the camera unit 110 is photographed, and is disposed in an area not overlapping with the lens to output infrared light to a predetermined area. The infrared lamp unit 140 includes at least one IR lamp.

The infrared lamp unit 140 moves in a direction substantially the same as the direction in which the camera unit 110 moves, and outputs infrared rays so that the camera unit 110 easily monitors the movement of an object even in a dark area.

In addition, the infrared lamp unit 140 is disposed so as not to overlap the area where the lens is disposed so that the camera unit 110 can photograph without distortion.

The shielding part 150 is formed between the camera part 110 and the dome cover part 130 to shield the infrared rays from being diffused into the dome cover part 130 and rush into the camera part 110. One end of the shielding part 150 is fixed to the camera part 110 while surrounding the lens, and the other end is in contact with the dome cover part 130 but is not fixed.

That is, one end of the shielding unit 150 is fixed to the camera unit 110, so that the other end of the shielding unit 150 is substantially the same as the camera unit 110 even when the camera unit 110 is operated in the horizontal or vertical direction. It can be supported so as to move in the direction can effectively block the infrared reflected by the dome cover portion 130.

A detailed description of the shield 150 will be described later with reference to FIGS. 3A to 4.

3A illustrates a shield according to an embodiment of the present invention, and FIG. 3B illustrates a shield according to another embodiment of the present invention.

Referring to FIG. 3A, the shielding part 150 according to an embodiment of the present invention is formed between the camera part 110 and the dome cover part 130 so that infrared rays are diffusely reflected on the dome cover part 130 so that the camera part 110 is provided. It is to shield the board from boarding.

The shielding unit 150 is formed in the form of a brush that can remove the dust accumulated on the dome cover unit 130 while shielding the infrared rays entering the camera unit 110.

That is, one end of the shielding unit 150 is fixed to the camera unit 110 while surrounding the lens, the other end is formed in the form of a brush is in contact with the dome cover unit 130 is not fixed.

As such, the other end of the shielding part 150 is formed in a brush shape, so that infrared rays reflected by the dome cover part 130 are efficiently shielded by the brush, and the camera part 110 is the dome cover part 130. While rotating the inside of the horizontal or vertical direction it can remove the dust and foreign matter accumulated in the dome cover 130. Accordingly, the camera unit 110 may capture a predetermined area on a clearer screen while shielding infrared rays that are diffusely reflected by the shielding unit 150 formed in a brush shape.

In addition, the camera unit 110 and the dome cover 130 may be directly contacted by the shielding unit 150 formed in the shape of a brush and maintain a predetermined interval so that the camera unit 110 may be smoothly in the horizontal or vertical direction. It can work. In addition, it is possible to effectively shield diffusely reflected infrared rays.

In FIG. 3A, the brush shape formed in the shielding part 150 is formed in one line, but is not limited thereto, and may be formed in more than one line.

Referring to FIG. 3B, the shielding part 150 according to another embodiment of the present invention may remove moisture accumulated at the dome cover part 130 while shielding infrared rays that are boarded into the camera part 110 and remove moisture. It is formed of microfiber or sponge.

That is, one end of the shielding unit 150 is fixed to the camera unit 110 while surrounding the lens, the other end is formed of a microfiber or sponge to be in contact with the dome cover 130, but not fixed.

As such, the other end of the shielding part 150 is formed of a microfiber or sponge, so that infrared rays reflected by the dome cover part 130 are efficiently shielded, and the camera part 110 is inside the dome cover part 130. Rotating in the horizontal or vertical direction can remove the dust and moisture accumulated in the interior of the dome cover portion 130.

In addition, since the shielding part 150 disposed on the camera part 110 is formed of a soft microfiber or sponge, the camera part 110 is horizontally or vertically in contact with the shielding part 150 and the dome cover part 130. Scratch does not occur inside the dome cover part 130 even when rotated in the direction.

Accordingly, the camera unit 110 may capture a predetermined area with a cleaner screen while shielding infrared rays diffused by the shielding unit 150 formed of soft microfiber or sponge.

In addition, although not shown in FIG. 3B, the shielding part 150 may be formed of a microfiber or a sponge having a predetermined thickness. As described above, the shield unit 150 is formed of a microfiber or sponge having a predetermined thickness, thereby protecting the camera unit 110 from an impact generated from the outside. That is, the shielding part 150 disposed between the camera part 110 and the dome cover part 130 functions as a buffer to absorb shocks generated from the outside. As a result, the shock absorbing from the outside is absorbed by the shielding unit 150, thereby protecting the camera unit 110 safely.

4 is for explaining that the shielding unit 150 is fastened to the camera unit according to an embodiment of the present invention.

Looking at Figure 4, the shielding unit 150 according to an embodiment of the present invention is fastened to the camera unit 110 in a spiral manner is fixed.

That is, the shield 150 is fastened by fastening the shield unit 150 to the camera unit 110 by rotating in the first direction, and rotating the shield unit 150 in the second direction opposite to the first direction. It is to detach the shield unit 150 to the camera unit 110 in a spiral manner that can be removed.

This is because the shield 150 is in contact with the dome camera unit 110 to operate together with the camera unit 110, the other end length of the shield 150 may be shortened to reduce the function of shielding the diffused infrared radiation. As such, when the function of shielding the infrared rays diffused by the shielding unit 150 is deteriorated, the shielding unit 150 is separated from the camera unit 110 in a spiral manner and the new shielding unit 150 is fastened and fixed. Thereby, maintenance of a product can be made easy.

In addition, the user can easily replace the shield 150 suitable for the surrounding situation or weather in a spiral manner in consideration of the surrounding environment or external weather. For example, in summer, when there is little crossover, the shielding unit 150 formed in the shape of a brush is fastened to the camera unit 110 and fixed, and the crossover is large and the microfiber yarns in spring and autumn generate a lot of moisture in the dome cover unit 130. Alternatively, the shielding part 150 formed of a sponge is fastened to the camera part 110 to be fixed.

5 is for explaining the operation of the PTZ camera device 100 according to an embodiment of the present invention.

Referring to FIG. 5, the shielding unit 150 is disposed in the camera unit 110 to block infrared rays diffused by the dome cover unit 130 according to an embodiment of the present invention.

The shielding part 150 is disposed between the camera part 110 and the dome cover part 130, one end of the shielding part 150 is fixed to the camera part 110, and the other end of the shielding part 150 is the dome cover part. It is formed in contact with 130. By being formed as described above, some of the infrared rays output from the infrared lamp unit 140 pass through the dome cover unit 130 and the other part is reflected by the dome cover unit 130 to effectively block the board through the lens. It is.

6 is a block diagram illustrating a PTZ camera device according to another embodiment of the present invention.

Referring to FIG. 6, the PTZ camera apparatus 200 according to another embodiment of the present invention may include a camera unit 210, a dome cover unit 230, an infrared lamp unit 240, a shielding unit 250, and a camera driver 220. ) Is configured to include.

The camera unit 210 monitors the movement of an object in a predetermined area.

The dome cover part 230 protects the camera part 210 from the outside and is formed to be fixed so as not to move.

The infrared lamp unit 240 operates in the same direction as the direction in which the camera unit 210 photographs, and outputs infrared rays to a predetermined area.

The shielding part 250 is formed between the camera part 210 and the dome cover part 230 to shield the infrared rays from being diffusely reflected by the dome cover part 230 and rushing into the camera part 210.

The functions of the respective components corresponding to the camera unit 210, the dome cover unit 230, the infrared lamp unit 240, and the shielding unit 250 described above, and the organic relationship therebetween are shown in FIGS. Since the functions of the respective components corresponding to the camera unit 110, the dome cover unit 130, the infrared lamp unit 140, and the shielding unit 150 described in FIG. 5 and the organic relationship therebetween are substantially the same. Each of these descriptions will be omitted below.

The camera driver 220 controls the position of the shielding part 250 while rotating the camera part 210 side to side and up and down while driving the camera part 210. The camera driver 220 includes a sensing unit 221 that senses brightness.

The sensing unit 221 provides a first signal to the camera driver 220 to contact the dome cover unit 230 with the shielding unit 250 when the sensed brightness is darker than the reference brightness, and when the brightness is brighter than the reference brightness. The second signal is provided to the camera driver 220 so that the shielding part 250 does not contact the dome cover part 230. Here, the brightness sensed by the sensing unit 221 is the brightness of the outside of the dome cover unit 230, and the reference brightness is the brightness preset by the user in consideration of the surrounding environment or the external environment.

In this case, the camera driver 220 rotates the camera unit 210 to the left and right to operate in a horizontal direction, and a tilt driver to operate the camera unit 210 in a vertical direction by rotating the camera 210 up and down. It includes, and receives the first signal or the second signal from the sensing unit 221 to provide a tilt (Tilt) driving unit to operate the shielding unit 250 in the vertical direction. Here, the tilt driver is physically connected to the shield 250.

In addition, the sensing unit 221 provides the camera driver 220 with a third signal that turns on the infrared lamp unit 240 when the sensed brightness is darker than the reference brightness. Accordingly, the camera driver 220 receives the third signal from the sensing unit 221 to turn on the infrared lamp unit 240 so that infrared light is output.

7a and 7b are for explaining the operation of the PTZ camera apparatus according to another embodiment of the present invention.

First, referring to FIG. 7A, the brightness sensed by the sensing unit 221 according to another embodiment of the present invention is brighter than the reference brightness.

The camera driver 220 receiving the second signal operates the shield 250 toward the camera 210 through the tilt driver so that the shield 250 does not come into contact with the dome cover 230. To deploy.

In this case, the sensing unit 221 may be a case in which the sensed brightness is brighter than the reference brightness or the room is bright. As such, when the brightness of the outside of the dome cover unit 230 is brighter than the reference brightness, the camera unit 210 may absorb a lot of light through the lens, so that the predetermined area may be captured more clearly.

That is, the diaphragm (not shown) formed inside the camera unit 210 may adjust the depth of focus and the movement (subject) of the object by photographing a predetermined area by adjusting the amount of light that is the amount of light. In other words, when the camera unit 210 absorbs a large amount of light through the lens, the camera unit 210 may increase the aperture value, thereby increasing the depth of the screen captured in the predetermined area. As described above, when the depth of the screen becomes deeper, the predetermined area can be captured more clearly.

Also, referring to FIG. 7B, the brightness sensed by the sensing unit 221 is darker than the reference brightness according to another embodiment of the present invention.

The sensing unit 221 provides a first signal to the camera driver 220 so that the shielding unit 250 contacts the dome cover unit 230 when the sensed brightness is darker than the reference brightness. The camera driver 220 receiving the first signal operates the shield 250 toward the dome cover 230 through the tilt driver so that the shield 250 is in contact with the dome cover 230. . Here, the sensing unit 221 may be a case where the sensed brightness is darker than the reference brightness at night or when the room is dark.

At the same time, the sensing unit 221 provides the camera driver 220 with a third signal that turns on the infrared lamp unit 240 when the sensed brightness is darker than the reference brightness. The camera driver 220 receiving the third signal receives the third signal from the sensing unit 221 to turn on the infrared lamp unit 240 so that infrared light is output.

That is, when the camera driver 220 is darker than the reference brightness, the camera driver 220 receives the first signal and the third signal through the sensing unit 221, outputs infrared rays, and at the same time, infrared rays diffused into the dome cover unit 230 through the lens. The shield 250 is operated to abut on the dome cover 230 in order to shield the camera unit 210 from boarding.

By operating the infrared lamp unit 240 and the shielding unit 250 in this manner, the infrared rays reflected by the dome cover unit 230 and entering the camera through the lens can be efficiently shielded, thereby making the predetermined area more clear. You can shoot.

In addition, the shield 250 is fastened to the camera unit 210 in a spiral manner is fixed. Detailed description thereof has been described in detail with reference to FIG. 4 and will not be described herein.
