Disclosed herein is a method of recording and reproducing surveillance images in a Digital Video Recorder (DVR). In one embodiment of the present invention, a recording speed such as a frame rate for surveillance images are controlled according to extent of motion of subjects in the surveillance detected through prediction between neighboring frames, and information about the controlled frame rates and information about time at which the frame rate is used may be managed and recorded in an associated manner. In another embodiment of the present invention, based on information about frame rates managed in associated with information about time at which the frame rate is used, specific frames from surveillance images on a recording medium are selectively reproduced, and a period in which frames are recorded at a frame rate higher than a specific rate may be selected and reproduced.
