Surveillance camera assembly for indoor and outdoor use}

Embodiments relate to a surveillance camera assembly for both indoor and outdoor use, and more specifically, a surveillance camera for both indoor and outdoor use that can be easily converted into an indoor surveillance camera and an outdoor surveillance camera and can use various types of supply power used indoors and outdoors. It's about assembly.

A surveillance camera is a device that is installed inside a building to photograph the interior or is installed outside the building to perform a function of photographing the surroundings of the building.

An outdoor surveillance camera installed outside a building requires a housing having a waterproof or dustproof function to protect electronic components from weather conditions such as rain and snow and dust.

Compared to indoor surveillance cameras, outdoor surveillance cameras have a more complex structure to protect the cameras, and product prices increase significantly in the process of manufacturing high-quality products demanded by consumers. For this reason, since the outdoor surveillance camera and the indoor surveillance camera are developed separately, it is difficult to use both the indoor surveillance camera and the outdoor surveillance camera.

Consumers may want to purchase an indoor surveillance camera or an outdoor surveillance camera and change its use while using it, but since there is no surveillance camera that can be used both indoors and outdoors, they must purchase a new product.

Recently, surveillance cameras for both indoor and outdoor use have been developed, such as Korean Patent No. 1260258, but this technology is used as an outdoor surveillance camera by covering the indoor surveillance camera with a waterproof cover with a crude design. It is difficult to achieve good performance. In addition, since the wiring connector supplying electricity to the surveillance camera exists only in a single position in the housing, the design of the outdoor housing and the indoor housing is limited because the limited position of the wiring connector needs to be considered.

Japanese Unexamined Patent Publication No. 2003-018439 describes a technique for converting a rectangular parallelepiped surveillance camera into an indoor surveillance camera and an outdoor surveillance camera. Such indoor/outdoor surveillance cameras are not only difficult to apply to surveillance cameras having dome-shaped housings, but also difficult to install surveillance cameras in various locations because both indoor and outdoor installation structures have the same shape.

In addition, since the outdoor surveillance camera uses a structure in which an outdoor cover is attached to the front and rear of the indoor surveillance camera, it is difficult to sufficiently protect the camera from the external environment when the surveillance camera is installed in a harsh environment, and the heat generated by the surveillance camera is effectively It's hard to deal with.

In addition, since the same type of camera cable and power cable must be used in both the indoor installation structure and the outdoor installation structure, the cable connection structure may be changed depending on the environment in which the surveillance camera is installed, or the surveillance camera's video signal or audio It is difficult to select various methods when transmitting signals to the outside.
