Description

Surveillance Camera with Lens Adjuster {CCTV CAMERA HAVING LENS ADJUSTER}

The present invention relates to a surveillance camera that can adjust the focus and zoom of the lens, in particular the focus and zoom adjustment of the lens unit installed inside the housing can be adjusted from the outside of the housing, and the heat dissipation cover is coupled to the rear of the housing The present invention relates to a surveillance camera equipped with a lens adjusting device capable of cooling the heat generated inside the housing.

In general, surveillance cameras are used for crime prevention in general homes or in places such as department stores, banks, exhibition halls, etc. to prevent and prevent intrusion, theft or fire in advance, and are installed to promptly deal with accidents. In general city roads and highways, a closed circuit television (CCTV) system, which is a closed circuit monitoring device, is used to control traffic conditions and violation vehicles.

Such a surveillance camera system is a television system that transmits an image to a specific receiver through a closed circuit, and is connected by wire or wirelessly from a transmission image to a reception image and cannot be arbitrarily received by the general public. In addition, the surveillance camera system is installed in a specific place for a special purpose and can monitor the image through a display unit installed at a remote place to monitor all situations, and is usually installed on the wall or ceiling of a building to monitor a large space as possible. It is generally set in a specific direction.

Accordingly, the focus and distance of the lens installed inside the surveillance camera should also be set at a specific position that the user wants to monitor. Therefore, it is required to provide a device for adjusting the image focus and distance of the subject. .

As described above, the conventional technology capable of adjusting the focal length of the lens is the "focal length adjusting device of the C-Citi camera" published in Korean Patent Publication No. 2001-0036209.

As shown in FIG. 9, the CSI camera focal length adjusting device includes a barrel 123 assembled to the front cover 122 of the case, and an adjustment ring 125 coupled to an outer circumference of the barrel 123. ), A slider 128 screwed to the adjustment ring 125, a printed circuit board 131 on which the slider 128 is fixed and movably supported by the front cover 122, and the printed circuit board. CCD 132 connected to the 131 and the lens filter 136 located between the CCD 132 and the lens 124, the slider 128 is provided with the lens filter 136 and CCD 132 The CCD housing 129 accommodated at intervals is integrally formed to rotate the control ring 125 forward or reverse to the lens 124 of the barrel 123 fixed to the front cover 122. The CCD 132 mounted on the printed circuit board 131 moves forward or backward so that the focal length of the subject can be adjusted. It is.

However, as the CSI camera focal length adjusting device rotates the adjustment ring 125, the slider 128 connected to the printed circuit board 131 and the CCD 132 moves back and forth to adjust the focal length. The printed circuit board 131 which moves back and forth has CSI installed inside the camera, so that the separation position of the CCD 132 with respect to the lens 124 cannot be confirmed from the outside and the zoom adjustment of the lens 124 is performed. Is possible, but the focus can not be adjusted.

In addition, the conventional CSI camera focal length adjusting device and the general surveillance camera is completely sealed, there is a problem that the interior of the surveillance camera is damaged by the heat generated from the circuit board or infrared LED installed inside the housing.

In addition, the conventional Citizen camera focal length adjusting device and a general surveillance camera is installed in a place to be monitored, in order to check the operating state of the surveillance camera by the display unit installed in another place by a cable state of the surveillance camera. Since it is necessary to check the failure of the surveillance camera or set again, there was a rather uncomfortable problem because it is not possible to directly check in the field.

In addition, the conventional CSI is a focal length control device of the camera and a general surveillance camera to transmit the video signal to the display by a cable, the cable is generally used for electronic devices, etc. is formed of a length of about 10 ~ 30m The monitoring camera and the display unit are connected to each other. As the distance between the monitoring camera and the display unit increases, the electric signal transmitted by the cable becomes weaker, so that the image displayed on the display unit is not clear and the image is interrupted.

The present invention is designed to solve the conventional problems as described above, an object of the present invention, the lens adjustment member rotatable on the outer peripheral surface of the housing is interconnected with the lens unit installed inside the housing to adjust the zoom and focus of the lens unit To provide a surveillance camera equipped with a lens adjustment device that can be adjusted through a simple operation from the outside of the housing.

Another object of the present invention is to provide a surveillance camera having a lens adjusting device coupled to the rear of the housing to effectively release the heat generated inside the housing to prevent the inside of the housing from overheating. It is.

In addition, the object of the present invention, the test terminal is connected to the connection jack of the electronic device on the rear of the housing can check the status of the surveillance camera directly in the field, as well as the balun terminal is connected to the LAN cable on the rear of the housing It is provided to provide a surveillance camera equipped with a lens adjustment device for transmitting a clear video signal to a display unit installed at a far distance.
