Dome closed circuit camera {DOME TYPE CLOSED CIRCUIT TELEVISION CAMERA}

The present invention relates to a domed closed circuit camera, and more particularly, to a domed closed circuit camera having a structure that improves sealing performance and efficiently alleviates heat generation inside to prevent external dust or moisture from entering the device. It is about.

In general, various types of cameras are used in CCTV (Closed Circuit Television) surveillance systems, but cameras installed on the ceiling, walls, or pillars of high-rise buildings rotate the internal camera module up, down, left, and right. In addition, a dome-type closed circuit camera (hereinafter, referred to as a dome-type camera) capable of adjusting tilt (tilting of the image in the horizontal direction) is mainly employed.

In addition, the conventional dome-shaped camera is installed in various spaces by mounting a round hemispherical transparent cover on the outside of the camera module to protect it from the external environment and not to recognize the shooting direction of the camera from the outside.

On the other hand, conventional dome-shaped cameras are often installed in a relatively high place, such as a ceiling or wall, the installation of the dome cover assembly must be separated from the camera body, wherein the dome cover assembly is connected to the camera body with a safety line The dome cover assembly is shaken from side to side, which makes it difficult to maintain the correct mounting position.

In addition, the camera installation work is usually performed in a single place in a high place, the installation is performed in such a way that the installer supports the camera body with one hand and screw the camera body with the other hand. As a result, cameras often fall during installation due to unstable posture.

In addition, the conventional dome-type camera may be installed outdoors depending on the situation, the outside moisture or dust can be introduced into the camera body, the airtight performance is required.

1 is an exemplary view showing a sealed structure of a conventional domed closed circuit camera. As shown in FIG. 1, the airtight structure of a conventional dome type camera is provided with a first packing member 5 between a transparent cover 1 and a ring cover 2 for fixing it, and the ring cover 2 and the camera body. It was made of a structure for providing a separate second packing member (6) between (4). As a result, two separate packing members 5 and 6 are mounted on the respective coupling surfaces, thereby degrading airtightness. In FIG. 1, reference numeral 8 denotes a camera module.

The first packing member 5 is generally formed in a 'c' shape, and is mounted along the circumference of the transparent cover 1 and fixed to the ring cover 2 by the packing member fixing plate 3. do. In this case, the packing member fixing plate 3 forms a ring shape of a flat plate, and a plurality of coupling holes 7 are provided and fastened to the ring cover 2 by screws. At this time, the first packing member 5 is sufficiently sealed near the screw fastening, but there is a problem that the sealing is weak between the screw fastening portion.

 On the other hand, the camera body is equipped with an infrared light emitting diode (IR LED) for self-illumination at night or a network transmission module for transmitting a video signal through the Internet network, such a device generates a high temperature heat In addition, a separate blower for dissipating it should be provided.

By the way, the camera module is a structure that flows at a predetermined angle in the camera body, while the blower is a structure fixed to the camera body when the angle of the camera module is changed, the blowing direction of the blower and the position of the heat generating portion of the camera module is dissipated heat dissipation performance There was a problem of this deterioration.

The present invention was devised by the above needs, and improves the sealing performance to prevent external dust or moisture from entering the device, it is more stable that the connection between the camera body and the dome cover assembly in the prior art It is an object of the present invention to provide a domed closed circuit camera having a structure that improves the hinge connection and efficiently alleviates heat generation inside.

According to an embodiment of the present invention for achieving the above object, the camera body is provided with a camera module, coupled with the camera body, and provided with a dome cover assembly provided with a transparent cover to protect the camera module A domed closed circuit camera is inserted and installed in a coupling surface between the transparent cover and the ring cover, and provides a domed closed circuit camera including an integrated packing member which abuts against the coupling surface of the camera body.

The packing member may include a first packing part covering a part of an edge of the transparent cover, and a second packing part extending from the first packing part to abut on the engaging surface of the dome cover assembly and the camera body part. .

The packing member may include a first fixing surface fixed to an inner circumferential surface of the dome cover assembly, and a second fixing surface extending from a portion of the first fixing surface and coupled to a portion of the camera body.

An extension part connecting the first fixing surface and the second fixing surface may be further included, and the extension may be formed to have a plurality of curved surfaces.

On the other hand, in order to prevent shaking or rotation during construction of the dome cover assembly connected to the camera body with a safety cord, the packing member extends from one side to the outside and is screwed to the camera body at the end thereof to open the dome cover assembly. Can act as a hinge to

On the other hand, the present invention, when the heat dissipation to the heat generated in the electronic circuit portion in the above configuration, the camera module is installed in the camera body to be able to adjust the angle, the camera module is formed with an extension portion, It is preferable to include a blowing fan that is fixed to the extension to ensure that the air flow is uniformly made to the camera module and the blowing fan is always the same position according to the angle adjustment of the camera module.

According to the present invention, it is possible to seal the edges of the camera body, the dome cover assembly and the transparent cover using one packing member, thereby improving the sealing performance and lowering the manufacturing cost.

In addition, the present invention has the effect of improving the heat dissipation performance inside the camera in a structure in which the blower flows together to correspond to the flow direction of the camera module.

In addition, the present invention can provide a safety and convenience when constructing a portion of the packing member to connect a portion of the camera body and the dome cover assembly.
