Description

CAMERA FOR CCTV INSTALLED INFRARED LED

The present invention relates to a surveillance camera equipped with an infrared LED, and in particular, the infrared generator for fixing the infrared LED can be integrally formed by simple assembly, and the infrared camera with the infrared LED fixed can be easily operated in one operation. The present invention relates to a surveillance camera equipped with an infrared LED that can be mounted on the camera.

Generally, it is installed in order to prevent intrusion, theft or fire in advance in general housing safety, department stores, banks, exhibition halls, etc., and to promptly deal with any accidents. Closed Circuit Television (CCTV) system, which is a closed circuit monitoring device, is used to easily check the operation status and process flow.

The surveillance camera is weak at night or without light or in a dark place where it is impossible to check objects, so the surveillance function is weakened. Therefore, a separate lighting means can be installed and used in the surveillance camera. Infrared light emitting diode (hereinafter referred to as LED) can be used to monitor more effectively because the person being photographed on the surveillance camera does not recognize the infrared light when the main monitoring target is a human.

In addition, the surveillance camera having the infrared LED is automatically supplied when the power falls below the set illuminance to operate the infrared LED, and to provide a more distinguished image through the light generated from the infrared LED, convenient to use in any environment. Therefore, the research and development and distribution of surveillance cameras with infrared LEDs are increasing rapidly.

However, the surveillance camera equipped with the infrared LED is not only expensive, but does not utilize the existing camera because the surveillance camera itself has to be replaced by a surveillance camera having a plurality of infrared LEDs therein. There was a problem that the material, manpower and time was wasted because it was not possible to do so and to install a new surveillance camera.

In order to solve the above problems, the Republic of Korea Utility Model Registration No. 20-0220883 "surveillance camera equipped with an infrared LED mounting hole" as shown in Figure 5, the body 12 'formed so as to open the front And a transparent window 13 'formed in the front opening of the body 12', and a cover body 14 which protrudes toward the front from the edge of the transparent window 13 'and blocks metering reflected by the CCD camera. In the surveillance camera consisting of a main body (11 ') consisting of', a through portion (15a ') formed to expose the transparent window 13' in the center, and a plurality of LEDs for mounting the infrared LED 16 ' An infrared LED mounting hole 15 'formed with fastening holes 15c' and 15d 'for fastening and fixing the mounting hole 15b' and the front surface of the surveillance camera by the coupling member 20 '; An LED mounting member (17 ') to which the infrared LED (16') is fitted and fastened is inserted into the LED mounting hole (15b '); Conventional surveillance cameras in which a hood 18 'with a lens 18a' mounted on its front surface is mounted on a front surface of the infrared LED attachment hole 15 'for adjusting an irradiation angle of the infrared LED 16', Infrared LED attachment port 15 'is simply attached to the existing surveillance camera so that it can be used as an infrared surveillance camera. Therefore, the existing surveillance camera can be utilized, and the installation time is very easy. It can be installed with minimum manpower, and existing surveillance camera can be replaced with infrared surveillance camera without any gap of surveillance system according to the replacement of surveillance camera, and hood 18 'is installed on the front of infrared LED 16'. Equipped with an infrared LED (16 ') is said to provide an effect that can be adjusted to some extent.

However, in order to install the infrared LED 16 'in the conventional surveillance camera, the threaded infrared LED 16' is coupled to the threaded LED mounting member 17 'and the LED mounting member 17' is mounted. After inserting the LED mounting hole 15b 'of the infrared LED attaching hole 15' again, the hood 18 'on which the lens 18a' is mounted is separately separated from the front surface of the infrared LED attaching hole 15 '. Since the installation takes a long time, and the number of parts to be combined, there is a problem that the manufacturing cost is increased, the LED mounting member 17 'coupled to the infrared LED 16' is the LED mounting hole (15b ') ) Is fixed by a general fit without any tightening means, so that the LED mounting member 17 'may be pulled out of the infrared LED attaching port 15' when the surveillance camera is moved.

In addition, since the CCD camera is installed inside the main body 1 'and the infrared LED mounting hole 15' is installed outside the main body 11 ', the penetrating portion 15a' of the infrared LED mounting hole 15 'is provided. ) Is not exactly aligned with the lens portion of the CCD camera, so that smooth shooting cannot be performed, and the hood 18 'is mounted on the front surface of the LED mounting hole 15b' of the infrared LED mounting hole 15a '. ) Has a problem in that the length itself is long and the diameter is wider toward the front part, so that the photographing field of the CCD camera lens part is obscured when the subject is photographed.

The present invention has been devised to solve the conventional problems as described above, the object of the present invention, the infrared LED can be integrated into the infrared generating unit through a simple assembly process, the infrared generating unit is fixed to the infrared LED It is to provide a surveillance camera equipped with an infrared LED that can be easily mounted on the lens unit in one operation.

In addition, another object of the present invention is to provide a surveillance camera equipped with an infrared LED is fixed to the lens unit itself, the infrared LED does not obstruct the field of view when shooting.

The above object of the present invention, the lens unit is provided on the front of the housing, the surveillance camera equipped with an infrared generating unit having an infrared LED for generating infrared illumination around the lens unit, the infrared generating unit, the lens in the center A fixing member having a center hole into which a negative focus control ring is inserted, a plurality of insertion holes into which infrared LEDs are inserted around the center hole, and an outer circumferential surface of which is formed to extend backward; A printed circuit board to which the infrared LED is fixed so as to be inserted into the insertion hole of the fixing member and inserted into the guide part of the fixing member; The printed circuit board is achieved by a surveillance camera equipped with an infrared LED, characterized in that it comprises a protective plate screwed to the fixing member to be fixed after being inserted into the guide portion of the fixing member.
