And a color infrared LED illuminating device integrated CCD camera for monitoring focusing from the outside.

In general, a CCD camera integrated with a color infrared LED illuminator for monitoring is used to photograph a situation occurring in a certain space and transmit and display it on a monitor installed at a remote location. That is, the manager confirms and observes the image captured by the CCD camera integrated with the color infrared LED illuminator for monitoring installed at a certain distance through the monitor. As a result, the manager can check the situation occurring remotely without visiting the site, and can manage the building, the parking lot, and the apartment more efficiently.

In addition, the CCD camera with integrated color infrared LED illuminator for monitoring can clearly photograph the place such as parking lot or apartment during the day, but it was difficult to photograph these places at night.

In order to overcome these disadvantages, a number of CCD cameras with integrated color infrared LED illuminators for surveillance can be photographed to capture a place to be observed or checked even at night by embedding an infrared LED that emits light in a wavelength band that is difficult to identify with human vision.

Referring to the effects of the present invention configured in this way in detail, as follows.

(Weekly operation)

First, during the daytime, the light incident through the transparent window 13 is measured by the light amount sensor 17 installed on the board 15 to determine the daytime when 2LUX or more and the nighttime when 2LUX or less, and the CCD 331 during the daytime. Is driven in the color mode, and the CCD 331 is driven in the black and white mode at night.

Next, the light inputted through the transparent window 13 and the lens unit 32 is converted into an electrical signal by the CCD 331 driven in the color mode, and then the lighting controller 332 controls the DSP 333. To supply. Subsequently, the DSP 333 removes the noise included in the input signal, converts the noise into an image signal, and transmits the same to the monitor 60 installed at a remote location for display.

(Night movement)

Next, when determined by the light amount sensor 17 at night, the infrared LED 16 provided on the board 15 is turned on and the CCD 331 is driven in the monochrome mode.

Next, the light inputted through the transparent window 13 and the lens unit 32 is converted into an electrical signal by the CCD 331 driven in the black and white mode, and then the lighting controller 332 controls the DSP 333. To supply. Subsequently, the DSP 333 removes the noise included in the input signal, converts the noise into an image signal, and transmits the same to the monitor 60 installed at a remote location for display.

In addition, when the infrared LED 16 is turned on, the DC fan 34 is also driven to discharge heat generated by the infrared LED 16 to the outside, thereby generating the transparent window 13 or the lens unit 32. It prevents moisture beforehand.

Meanwhile, when the front case 11 and the rear case 67 are screwed together, the outer ring 21 which is tightly fixed to the inside thereof prevents water or moisture from invading from the outside, The shielding part 50 provided prevents rain or water from penetrating into or penetrating the inside.

In addition, when the fixing member 40 and the rear case 67 are combined to install the monitoring CCD color camera at a predetermined place, perspectives protruding from the lower end of the lens unit 32 according to the distance of the place to be monitored and The focus is adjusted using the focus adjusters 31a and 31b and the distance is adjusted at the same time. That is, since there is no such function in the related art, in order to focus or adjust the distance, the front case 11 and the rear case 67 need to be disassembled and focused, and after adjusting the distance, they must be assembled and installed again. There was a feeling.

In addition, there is a difference in the amount of light depending on the place where the surveillance CCD color camera is installed. In order to solve this problem, the adjustment level of the auto iris is adjusted to the required amount using the DC level adjusting unit 34 provided at the lower end of the lens unit 32.

As described above, according to the present invention, when the front case and the rear case are screwed together, the outer ring is tightly fixed to the inside, and a shielding part is further installed on the outer upper surface, so that rain or water or moisture invade the inside. There is an effect that can be prevented or soaked.

In addition, according to the present invention, regardless of the installation location of the CCD camera with integrated color infrared LED illuminator for monitoring and focusing from the outside using the perspective and focus control unit without disassembling the CCD camera with integrated color infrared LED illuminator for monitoring The effect is that the distance can be adjusted.
