A multi-area monitoring system of a CCTV having a camera quadratic curved surface mirror structure and a method for correcting a distortion image thereof are provided to maximize image recovery force of the system and obtain high quality of the image by selecting an unwrapping region, cropping the curved area of an region of interest, and unwrapping the curved area. A multi-area monitoring system of a CCTV having a camera quadratic curved surface mirror structure comprises a camera device part(2), an image signal processor(3), and a computer device part(5). The camera device part photographs remote distance images of all directions through a camera unit(1). The image signal processor converts the remote distance image signal into an image data. The computer device part selects an unwrapping region of the image data, makes the unwrapping region into an ROI(Region Of Interest), crops/unwraps necessary curved areas of the ROI, converts the curved areas into plane images, displays the plane images on a monitor(4), and recovers the plane images into an original image through an image calibration process.
