TECHNICAL FIELD OF THE INVENTION
The present invention relates to a housing for a surveillance camera.
[0002]
[Prior art]
Conventionally, as a housing for a surveillance camera, for example, there is one shown in US Pat. No. 5,852,754. That is, the interior of the housing is pressurized in order to improve the protection function for the camera parts. An improved version of the surveillance camera housing is disclosed in International Publication WO 01/75833. That is, a device such as a circuit board is attached to the back surface of the pivoting portion connected to the fixed portion by a hinge with respect to the fixed portion, so that work on the device can be easily performed.
[0003]
[Problems to be solved by the invention]
However, the housing for a surveillance camera disclosed in WO 01/75833 has a device on the back of the pivoting portion when the pivoting portion is rotated by the hinge, since the pivoting portion is hinged to the fixed portion. Hangs with the pivot portion and is located between the housing shell and the pivot portion. For this reason, when performing the maintenance and inspection work from below the housing, there is a problem that it is difficult to see the device on the rear side of the pivot portion, and it is difficult to perform the maintenance and inspection work.
[0004]
The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a surveillance camera housing that facilitates maintenance and inspection work.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a surveillance camera housing according to the present invention includes an upper case, a lower case, and a substrate, wherein the upper case and the lower case are mutually opened and closed so as to form a storage chamber therein. The lower case is made of a transparent material, the substrate has a camera mounting surface on which a monitoring camera can be mounted, and a control device mounting surface on which a control device of the monitoring camera can be mounted; A mounting surface is provided inside the housing chamber with the control device mounting surface facing the lower case side and the control device mounting surface facing the upper case side, and is rotatably mounted inside the upper case around an axis along the camera mounting surface. Is characterized.
[0006]
The surveillance camera housing according to the present invention is used by attaching a surveillance camera to a camera attachment surface and attaching a control device to a control device attachment surface. Since the lower case is made of a transparent material, the lower case can be photographed by the monitoring camera from the accommodation room. The lower case may be made of any material such as colorless and transparent, colored and transparent, translucent, and net-like, as long as the lower case can be seen by the monitoring camera. A solar panel for supplying power to the monitoring camera and its control device may be attached to the outer surface of the upper case.
[0007]
In the surveillance camera housing according to the present invention, the lower case is removed from the upper case when performing maintenance work or the like. Since the surveillance camera is mounted on the camera mounting surface of the board and arranged on the lower case side, maintenance and inspection work can be easily performed. When performing maintenance and inspection of the control device of the surveillance camera, the board is rotated about an axis along the camera mounting surface. The control device mounted on the control device mounting surface can be directed from the upper case side to the lower case side by the rotation of the substrate. Thereby, the maintenance and inspection work of the control device can be easily performed. After the maintenance work inside the accommodation room, attach the lower case to the upper case.
[0008]
In the surveillance camera housing according to the present invention, it is preferable that the substrate is detachably attached to the upper case. In this case, since the board can be attached to the upper case after the surveillance camera and the control device are attached to the board, the attachment work of those devices can be facilitated. In addition, in the case of maintenance and inspection work in which it is difficult to perform the operation with the board attached, the entire camera can be removed and the maintenance and inspection work of the monitoring camera and the control device can be performed, so that the maintenance and inspection work can be facilitated.
[0009]
In the surveillance camera housing according to the present invention, it is preferable that a speaker and a microphone are integrally provided in the upper case or the lower case. In this case, the speaker can issue an alarm or a warning, and the surroundings can be secured based on the monitoring result. In addition, since the microphone can capture audio together with the video of the monitoring camera, the monitoring capability can be improved. The speaker may have a configuration in which the upper case vibrates so as to drop snow accumulated on the upper case when sound is emitted. In this case, when snow piles up on the upper case, a warning of "snowfall" is issued from the speaker, and the speaker vibrates to drop the snow accumulated on the upper case, and the weight of the snow bears on the support members. Can be prevented.
[0010]
The surveillance camera housing according to the present invention has an electric heater and an electric fan for preventing dew condensation on the lower case inside the accommodation room, and supports the upper case to support the electric heater, the electric fan, and the monitor. It has a wiring for supplying power to the camera and the control device, and a support pipe capable of housing an optical cable for transmission and reception of the control device, and the substrate has a gap between the upper case and the upper case where a hand can be inserted. It is preferable that the substrate is provided inside the storage chamber and the substrate is mounted so as to be rotatable by 180 degrees about the axis.
[0011]
In this case, the electric heater can prevent dew condensation and snow accumulation, and protect the monitoring camera and the control device from abnormal operation due to low temperature. The electric fan diffuses the heat of the electric heater, and can enhance the dew condensation prevention effect, the snow accumulation prevention effect, and the protection effect from low temperatures. The support pipe supports the upper case and protects power wiring and optical cables. It is preferable that the surveillance camera has a drive device that enables remote control by an optical cable.
[0012]
In the surveillance camera housing according to the present invention, the work of removing and rotating the board can be facilitated by inserting a hand between the board and the upper case. Since the board can be rotated by 180 degrees, the work of mounting the control device and the maintenance and inspection work can be performed more easily.
[0013]
The surveillance camera housing according to the present invention may have a configuration in which the upper case and the lower case are hermetically closed so that the storage chamber can be pressurized, or may have a configuration in which the storage chamber is not pressurized. . When the accommodation chamber is not pressurized, the structure can be simplified, the manufacturing cost can be reduced, and the maintenance and inspection work can be facilitated.
[0014]
