摘要： The present invention relates to an image quality adaptive video security system, a security camera generating an original video signal from a camera sensor, inserting an image quality discrimination signal including image quality information for video to the original video signal and generating a video signal. A DVR system determines whether a video signal from a security camera is transmitted in an analog transmission scheme or in a digital transmission scheme. In the case of the analog transmission scheme, the DVR system decodes the analog video signal to a first digital component video signal and detects image quality information. In a case of the digital transmission scheme, the DVR system converts the digital video signal to a digital second component video signal and detects image quality information. A video processing unit scales, compresses, stores or displays the first or the second component video signal with reference to the image quality information of the detected analog or digital video signal.
