The present invention relates to an epoxy-impregnated housing surveillance camera and a manufacturing method for solving the problem of damage caused by the camera, and to completely prevent the penetration of moisture, dust, and gas foreign substances into the camera housing.

In general, CCTV cameras are commonly used on walls or ceilings or underwater to prevent accidents and accidents that may occur due to internal or external causes, to secure evidence of recorded images, or to record and store video data such as important facilities. It is a CCTV camera that is the core among closed circuit devices that can be installed and recorded in a place such as a pipeline or other place where surveillance and observation is required.

Conventional surveillance cameras for CCTV is producing and spreading a housing for protecting the camera in a plastic or aluminum or aluminum alloy, metal casting structure constituting the body of the camera. CCTV camera module is combined inside the housing, and the combination is composed of camera module, camera lens, LED module, and power supply unit. At this time, looking at the technology and assembly structure of the conventional or current CCTV camera has a number of structural problems! First, it is a structure that is weak in the waterproof problem that moisture can penetrate into the housing, and second: condensation occurs in the front of the camera lens or inside the housing due to the temperature difference between the heat generated inside the camera and the outside of the camera. Third: If the environment is poor due to the structure that is vulnerable to the external environment, dust or insects will penetrate into the camera housing and cause a malfunction. Fourth: It has a weak structure that can explode under the pressure of the camera, especially under water or similar environment, and has a problem of housing material and structure which can corrode inside and outside of the camera which can be caused by the bad condition. . This structure is a structure that can not fundamentally solve the prevention of penetration of dust or foreign matter, moisture or moisture or corrosive gas.
