Abstract

PROBLEM TO BE SOLVED: To pick up and monitor objects in two directions at the same time by installing plural television cameras to pick up an external state through a window to a frame provided in the interior of the case. SOLUTION: The cylindrical case 1 is provided with windows 2, 3 ensuring sights of monitor television cameras 8, 9 and a frame 6 for the installation of the cameras or the like and the monitor television cameras 8, 9 are fixed to the frame 6 via an image pickup direction angle adjustment device. That is, the two monitor television cameras 8, 9 are installed to monitor objects in directions different from 90 deg. and they pick up an external state through the monitor windows and the obtained video signal is displayed on the monitor arranged in a building via an underground path from the lower part of the camera case. Furthermore, the cylindrical shape is adopted for the shape of the camera case 1 so that the external sights are monitored without being spied on the internal monitor television cameras 8, 9 or their sight directions externally.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera case suitable for application to a surveillance television camera, and in particular,
When installed in a building or near a building or in a park,
The present invention relates to a camera case that is suitable for those environments and is suitable for obscuring that a surveillance camera is installed.

2. Description of the Related Art In a conventional surveillance television camera device, a camera case usually has a single camera housed inside, and its main purpose is to protect it from sunlight, wind and rain. It was easy to see at a glance whether the direction was being monitored. Therefore, for example, four camera cases are required to monitor the four sides of the building, which is economically expensive.

[0003]

SUMMARY OF THE INVENTION Conventional camera cases
Since only one camera is mounted on the housing, four camera cases are required to monitor the four sides of a building or the like, which is economically expensive and is obviously unfavorable in terms of aesthetics. An object of the present invention is to solve the above problems and provide a camera case having a simple structure in which the monitoring direction is difficult to detect.

[0004]

In order to achieve the above-mentioned object, the present invention has a tubular shape, and a plurality of windows are provided on the side surfaces in different directions perpendicular to the axial direction thereof, and a frame is provided inside thereof. It is configured such that a plurality of television cameras for picking up an image of the external situation can be installed in the frame through the window. As a result, for example, by mounting two cameras and changing the angle of the cameras, it is possible to simultaneously monitor in two directions.
Although two camera cases are required, the number of camera cases installed in the present invention may be two. Also, the shape is tubular,
It is suitable for surveillance because it is difficult for an intruder being monitored to know in which direction the camera is facing.
It is a camera case that has all the advantages of maintainability and installation.

1 shows an embodiment of a tubular camera case of the present invention. (A) is a front external view, (b) is an assembly drawing seen from the left side. In this embodiment, the tubular case 1 is cylindrical and has a diameter of about 32 cm, a height of about 170 cm, and a material of stainless steel. 1a is a roof part, and 1b is a fixed part to the base. Further, 2 and 3 are windows for securing the field of view of the surveillance television camera, 4 is an air intake port provided with a filter, 5 is a ventilation fan, 6 is a frame for installing a camera and the like, and 7 is an inside. This is a heater that automatically turns on the power when the temperature of 5 ° C or less. In the figure, the state where the surveillance TV camera is installed is shown by a broken line,
Reference numerals 8 and 9 denote surveillance TV cameras, which are fixed to the frame 6 via an imaging direction angle adjusting device. The tubular camera case can be divided slightly above the central portion in the vertical direction. When installing a camera device or the like, after fixing the frame 6 with the camera or the like installed at a predetermined position to the lower part of the case, Attach so that the top of the case is covered from above.

A case where the camera case configured as described above is applied to a surveillance television camera device will be described. Two surveillance television cameras 8 and 9 are installed so as to be able to observe in different directions by 90 °. The external situation is imaged through the respective monitoring windows, and the obtained video signal is projected from the lower part of the camera case to the monitoring monitor located in the building via the underground. Power supplies for the TV cameras, 8, 9, the heater 7, the ventilation fan 5 and the like are also arranged in the same manner as the above path. The ventilation fan 5 discharges the internal air, and the outside air is taken in through the air intake 4. When the temperature falls below 5 ° C., the power of the heater 7 is turned on and the internal air is heated so that the operation of the surveillance camera is not hindered. Further, heater glasses are used for the monitoring windows 2 and 3, and the power is constantly turned on to prevent the glass from fogging or dew condensation caused by a temperature difference between the inside and the outside. The monitoring window has a structure that does not protrude from the outer circumference of the case so that the imaging direction is difficult to see.

Since the camera case of the present invention has a cylindrical outer shape, in particular, a cylindrical shape, it is suitable for monitoring without having to clarify the internal monitoring camera or its monitoring direction from the outside. Moreover, since the position where the camera is installed inside the camera case is almost at the eye level of the human eye, when the monitoring system is configured, the monitoring image can be viewed without any discomfort. Further, it is economical because a plurality of cameras are installed in one case, and as shown in FIG. 2, one surveillance camera is installed in each of two diagonal corners of one building 10. By arranging 11 and 12, and monitoring the surroundings of two sides of a building that differ by 90 ° in the direction of the arrow, for example, by constructing a surveillance camera system using two camera cases, Since the circumference can be monitored, it is extremely efficient. In the above embodiments, the case has been described as having a cylindrical outer shape, but the cross section may be quadrangular, pentagonal or the like.

[0008]

By using the camera case of the present invention, it is possible to construct a television camera system for monitoring a plurality of positions so as to be sufficiently economically and environmentally satisfactory. .
