Abstract

PROBLEM TO BE SOLVED: To prevent the image pickup of a range where monitoring (image pickup) by a monitoring camera provided with a turning device is not permitted. SOLUTION: The monitoring camera is provided inside a camera case 1 and is turned by a turning device 2 and monitoring is performed. The monitoring camera is covered with a dome case formed in a semispherical shape by a transparent member and a blind is provided on a part pertinent to the range where the image pickup by the monitoring camera is not permitted in the dome case. For the blind, an opaque paint, for instance a black paint, is applied or an opaque sheet, for instance a black sheet, is stuck.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring camera device, and more particularly to a device for limiting a monitoring range.

[0002]

2. Description of the Related Art A surveillance camera (hereinafter, abbreviated as "camera") equipped with a turning device must not be monitored (imaged) in a turning range due to infringement of privacy or corporate secrets. May not). For this reason, for example, a turning device is provided with a limit switch to prevent the camera from turning outside the range set by the limit, so that the non-capturable range does not enter the viewing angle of the camera. Can only be set at one location (there is no turning to the right or to the left), and in a camera with a zoom lens, it is difficult to limit the imaging range by restricting the turning when the lens is wide-angled. .

[0003]

SUMMARY OF THE INVENTION According to the present invention, even when there are a plurality of areas within the turning range of the camera which must not be monitored (imaged), or even in the case of a camera equipped with a zoom lens, the non-monitoring range is ensured. It is an object of the present invention to prevent an image from being picked up.

[0004]

In order to achieve the above object, in a surveillance camera device according to the present invention, a surveillance camera provided with a turning device is covered with a hemispherical or spherical dome cover formed of a transparent member. A blindfold is provided at a position corresponding to a viewing angle that must not be imaged by the surveillance camera.

The blinds are formed by applying an opaque paint to the dome cover.

The opaque paint is, for example, a black paint.

[0007] It should be noted that a paint that can be removed with a solvent is used so that it can be applied again.

Alternatively, it is assumed that a sheet formed of an opaque material is attached to the dome cover.

The sheet is, for example, a black sheet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is a configuration diagram of a main part of an embodiment of a monitoring camera device according to the present invention, and FIG. 2 is an example of a dome cover. In FIG. 1, reference numeral 1 denotes a camera case in which a surveillance camera is provided. Reference numeral 2 denotes a turning device that turns the surveillance camera provided inside together with the camera case 1. Reference numeral 3 denotes a dome cover formed of a transparent material in a hemispherical shape. In FIG. 2, reference numeral 11 denotes a blindfold, which is provided at a position corresponding to a viewing angle of the dome cover 3 which should not be imaged by the monitoring camera. The figure shows an example in which two parts are provided. The blinds 11 are coated with an opaque paint, for example, a black paint, or a sheet made of an opaque material, for example, a black sheet is adhered, and light is prevented from entering the lens of the surveillance camera in this range. When applying the paint, a paint that can be removed with a solvent is used so that the paint can be reapplied when the blindfold area is changed or corrected. Although the dome cover 3 has a hemispherical shape in the above description, it may be formed in a spherical shape so as to cover the camera case 1 to the lower side.

In order to provide the blindfold 11, for example, the turning device 2 is turned while watching the image from the surveillance camera on the monitor, and the position (orientation) is used when a zoom lens is used for a position where monitoring (imaging) should not be performed. ) To widen the zoom lens, and apply black paint or the like to the dome cover 3 while watching the monitor screen, cut the black sheet or the like into an appropriate size, or affix an appropriate number of sheets. Figure 2 is a blindfold
Although this is an example in which 11 is provided at two places, it is also possible to provide a small piece at two or more places by such a method.

From the side to be monitored, the dome cover 3
Since it can be seen that the part facing the user is colored, it is possible to confirm that the surveillance camera is not imaged even when the surveillance camera turns. When there is a change in the range that should not be monitored, in the case of paint, the paint may be peeled off using a solvent and a new paint may be applied, and in the case of a sheet, it may be re-applied.

As described above, since the dome cover 3 covering the surveillance camera is provided with the blindfold, it does not require a complicated structure or circuit, is relatively inexpensive, and can easily change the blindfold range.

[0014]

As described above, according to the surveillance camera device according to the present invention, the surveillance camera having the turning device is covered with the hemispherical or spherical dome cover formed of a transparent member, and the surveillance camera of the dome cover is provided. Because the part corresponding to the viewing angle that should not be imaged is blindfolded with black paint or a black sheet, it is possible to ensure that the area that should not be monitored is not imaged, no complicated structure or circuit is required, And it can be implemented reliably at a relatively low cost.
