<p>The object of the present invention is to provide a monitoring video system that records high-quality video images over a long period. The monitoring video system of the present invention includes cameras (1-4), a codec (5-8) for encoding the video data output from the cameras (1-4), a magnetic disk (11) for temporarily storing the encoded video data output from the codec (5-8), and a digital VTR (12) for recording the encoded video data stored on the magnetic disk (11). Frame data are sampled from video data in at least one of the data transmission from the codec (5-8) to the magnetic disk (11) and the data transfer from the magnetic disk (11) to the digital VTR (12) to decrease the frame rate of the video data. When data is transferred to the archive device, edited data are intermittently transferred, and the recording operations of the digital VTR (12) device are synchronous to the data transfer.</p> |
