Description

CCD camera apparatus {CCD camera apparatus}

The present invention relates to a CCD camera device.

In general, a surveillance camera widely used as a CCD camera uses a CCD (Charge Coupled Device) element and is installed and used in a place where a fixed monitoring such as a bank or a parking lot is required.

The CCD camera has a front cap coupled to the front end of the camera body case, and a rear cap coupled to the rear end. The zoom lens module, the CCD module, and the rear PCB board are provided in the case in order from the front end to the rear end. The zoom lens module is supported by the lens holder and fixed in the case, and the CCD module is installed between the lens holder and the rear PCB substrate.

The CCD camera having the above configuration is configured to operate by receiving either AC power or DC power to the rear PCB board. That is, a CCD camera to be used in an area using AC power is provided with a PCB board for AC power in a case. In this case, AC power is supplied and converted into DC power to use the CCD camera as an operating power source.

On the contrary, in order to use a CCD camera in an area where DC power is mainly used, a DC power PCB board is installed in a case.

As such, since the power specifications are different for each region, the CCD cameras to be released are produced and released separately for AC power and DC power. However, in manufacturing and producing and selling CCD cameras exclusively for each AC and DC power supply as described above, there is a problem that productivity is low and it is difficult to actively cope with market changes. In addition, there is a problem that the production line and assembly process, such as each model is increased, the productivity is lowered and the cost is increased.

The present invention has been made to solve the above problems, and an object thereof is to provide an improved CCD camera device to selectively use AC and DC power supplies.
