CCTV Cameras {ＣＴＴ CAMERA}

The present invention relates to a closed-circuit surveillance (CCTV) camera (hereinafter abbreviated as "CCTV") camera, and more particularly to a CCTV camera including a waterproofing means to have water resistance against rainfall or snowfall. .

As is well known, CCTV cameras are widely used for surveillance in places where significant expenses are required, such as financial institutions. These CCTV cameras are usually set to face a specific direction on the wall or ceiling of a building.

1 is an exploded perspective view showing the structure of a CCTV camera according to the prior art.

In general, the CCTV camera includes a CCTV camera body 10, a barrel assembly 20 and a main board 30 interposed therein.

The CCTV camera body 10 is provided with an upper case 11, a lower case 12 and a front case assembly 13 having a fastening hole 11a to which the CCTV camera holder is connected. Each of the upper and lower cases 11 and 12 includes a plurality of screw fastening portions 14a formed at positions corresponding to each other, and are coupled by screws 14 passing through the screw fastening portions 14a. On the other hand, the decoration cover is interposed between the upper and lower cases (11, 12) serves to seal the coupling end. The front case assembly 13 is coupled to an open front portion of the body to which the upper and lower cases 11 and 12 are coupled, and is provided as a front case 13a and a front case cover 13b. The through-hole lens hole 13c is formed near the center of the front case 13a and the front case cover 13b so that the barrel assembly 20 which will be described later may collect an image.

The barrel assembly 20 is interposed inside the CCTV camera body 10 and generates an image by setting a focal point at a predetermined magnification of an image obtained from the front, and converting the generated image into an electronic signal 21. ) Is installed.

The main board 30 is connected to the barrel assembly 20, converts the image information converted into an electronic signal in the CCD assembly 21, and transmits the image information to the user side through the terminal unit 31.

However, when the CCTV camera assembled as described above is used indoors, there is no fear of water leakage. However, when the outdoor CCTV camera is installed without a separate housing, water leakage may occur due to climate change, for example, precipitation or snowfall. It can cause malfunction of CCTV cameras composed of electronic and optical devices.

The present invention has been conceived in view of the above, it is an object to provide a CCTV camera that can have a water resistance against precipitation or snowfall even when installed without a separate housing in both indoors and outdoors.

According to a preferred embodiment of the present invention, the waterproof means, it is preferable to include a protrusion rib and a leakage preventing groove formed complementary to each other at the coupling end of each of the plurality of cases.

The case may include an upper portion, a lower portion, and a front case, and the waterproof means may further include a waterproof window installed on the front case.

The terminal portion may be provided to face the bottom surface of the main body.

In addition, a speaker assembly for outputting a sound signal is installed on the main board, and the speaker assembly is preferably installed to face the bottom surface of the main body.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

CCTV camera 100 according to the present invention, as shown in Figures 2 to 5b, includes a CCTV camera body 110, the main board 120 and the waterproof means interposed inside the CCTV camera body 110. do.

The CCTV camera body 110 is provided with an upper case 111, a lower case 112 and a front case assembly 113 including a support fastening portion 111a to which the CCTV camera holder is connected. The upper and lower cases 111 and 112 are fastened by the coupling screws 116, and the front case 113 is coupled to the opened front part.

The upper case 111 includes a support fastening portion 111a so that a support (not shown) supporting the CCTV camera 100 can be connected. A female thread may be formed on the inner circumferential surface of the support fastening portion 111a such that the support is screwed together.

The lower case 112 is engaged with the upper case 111 to form a body of the CCTV camera 100, the front portion is formed to be opened. And, it includes a seating portion 114 having a plurality of through-holes (114a) in which the speaker assembly 124 to be described later, and a terminal hole (115).

Each of the upper and lower cases 111 and 112 includes a plurality of screw fastening portions 116a formed at positions corresponding to each other, and are coupled by screws 116 passing through the screw fastening portions 116a.

The front case 113 is coupled to the front opening of the CCTV camera body formed by the combination of the upper and lower cases 111 and 112, and a screw seating portion 113a (see FIG. 5A) is formed to be screwed together. In addition, the lens hole 113b penetrates to approximately the center thereof.

The main board 120 is interposed between the upper and lower cases 111 and 112, and a barrel assembly 121 for collecting image information and a CCD assembly 122 for converting the collected image into an electronic signal are connected to each other. do. The converted electronic signal is output to the outside through the terminal unit 123 provided on the main board 120. The terminal 123 is installed below the main board 120 to face the bottom of the lower case 112.
