CCTV A CCTV DEVICE FOR MINIMIZES BLURRING OF ANGLE OF VIEW USING ASPHERICAL SURFACE HEMISPHERE DOME

摘要

The present invention relates to a CCTV apparatus which minimizes the angle of view blur due to an aspherical hemispherical dome, and more specifically, a CCTV apparatus which minimizes the angle of view blur due to an aspherical hemispherical dome. The CCTV apparatus is fixed to a ceiling or a wall A camera fixing body having a base and a plate on which a camera lens module is installed; A camera lens module disposed on a plate of the camera fixing body, the camera lens module capturing an image of a surveillance area; A camera lens module driving unit coupled to the camera lens module unit disposed on the plate of the camera fixing body and driving to adjust a tilt angle of the camera lens module unit; And a dome housing coupled to the camera lens module driving unit to cover and protect the camera lens module unit disposed on the plate of the camera fixing body and fastened and fixed to the camera fixing body, And a structure of an aspherical hemispherical dome type structure capable of minimizing the blurring of the angle of view of the lens module part. According to the CCTV apparatus having the aspheric hemispherical dome, which minimizes the angle of view blurring, the CCTV apparatus includes a camera fixing body, a camera lens module unit, a camera lens module driving unit, and a dome housing. The housing is configured as an aspherical hemispherical dome-shaped structure that minimizes the blurring of the angle of view, thereby minimizing the blurring of the image on the image taken through the camera lens module and thus shooting the image without the blind area . According to the present invention, a dome housing having a hemispherical shape and a double-sided aspheric portion formed integrally with the dome cover are formed, thereby forming a space that can be rotated at a tilt angle of 85 degrees in the camera lens module , It is possible to photograph even an image of 90 degrees when zooming 5 times in the camera lens module part.
