Camera protection case device {A CASING APPARATUS FOR PROTECTING CAMERA}

The present invention relates to a camera protective case device, and more particularly to a camera protective case device to improve the camera shooting environment according to the conditions of the climate.

As society becomes more complex and urbanized, cameras are installed in many places to effectively prevent and manage incidents and accidents as well as to manage traffic systems.

In general, surveillance cameras such as CCTV cameras are installed in the interior and exterior of the building, street lamps, traffic lights, or poles that are separately installed to monitor the surroundings.

Among these surveillance cameras, especially when installed outside, they are exposed to adverse conditions such as wind, rain, snow, and the sun. Therefore, when exposed to a bad environment for a long time, the performance of the camera made of electronic devices and lenses are reduced and its life is shortened, and there is a problem that normal operation is not performed due to a small malfunction or failure.

For example, in the summer, the case where the camera is installed may be exposed to high temperature for a long time and maintained higher than the outside temperature. Therefore, the electronic parts may malfunction or fail to operate normally. Since the exposure, the operation efficiency of the camera is lowered, there is a problem that the operation of the electronic components are not made smoothly.

In addition, the transparent window of the portion corresponding to the camera lens in the camera case is contaminated with dust when used for a long time, there is a problem that the captured image of the camera is not clear, and the worker has to clean it by using a ladder truck, etc. There was discomfort.

In addition, during the daytime, sunlight is strongly reflected. In this case, if strong sunlight directly shines on the transparent window corresponding to the camera lens, it is difficult to obtain a clear image due to strong backlighting when the camera is photographed. There was this.
