Description

Dome Camera {DOME CAMERA}

The present invention relates to a dome camera, and more particularly, to a dome camera which is configured to prevent moisture and moisture entering from the outside, and which is capable of moisturizing moisture and moisture generated by a temperature difference from the inside of the camera .

In general, surveillance cameras are installed in offices, homes, hospitals as well as inside and outside of banks and public buildings requiring security. They are widely used for access control and crime prevention. In recent years, underground parking lots Are often installed in roads or in residential areas where accidents occur frequently.

Such a camera can be distinguished as a dome type, a set type, a bullet type, and a miniature type according to the installation type. Among them, a domed dome camera having a transparent dome and a photographing apparatus in which the pan / tilt driving can be performed is widely known. In addition, the dome camera adopts a hemispherical shape that can be easily accessed in the interior lighting device of the interior as a basic design element, which reduces the feeling of discomfort felt by the subject and is widely used because it matches well with the interior of the interior.

On the other hand, although the above functions are important, the waterproof property is also very important in that the water and foreign matter are prevented from penetrating because it is always installed in the outdoors, and is exposed to snow and rain water and dust floating in the air at all times.

Particularly, when the water penetrates into the camera, the waterproof property is a very important function in the surveillance camera because the foreign body is attached to the lens and the quality of the image is lowered when the water penetrates into the camera, As a conventional technique for enhancing waterproofness, Korean Patent No. 10-1351068 "Surveillance camera with enhanced waterproofness" is disclosed.

However, conventional cameras can not solve moisture and moisture naturally occurring due to a temperature difference occurring between the inside and the outside, a rainy season in summer, and the like. In order to prevent such problems, in the field, simply by inserting silica gel into the camera, it is not only temporary but also can not remove the moisture when the silica gel reaches its end of life. In order to insert the silica gel, Assembled, which is one of the factors that lowers the water resistance.

Furthermore, in order to enhance only the waterproof property, it is necessary to acquire a waterproof grade, so that the development cost and the development period of the technology are getting longer. Therefore, in the present invention, a dome camera having a waterproof property and a structure capable of regulating moisture and humidity therein is disclosed.
