  • the image displayed by the display device is monitored by a supervisor, and is recorded in a video recording medium such as videotape by a video recording device such as a VTR or VCR.
  • the video monitoring system using an analog method described above has the following disadvantages. Since the image is recorded in the video recording medium, the supervisor has to change the videotape in certain time cycle and has to write a shooting date and a shooting time of the filmed image on the videotape. In addition, in order to fine a desired scene in the recorded image, the supervisor has to look over the corresponding videotape according to a shooting date and a shooting time in full.
  • the problems of the analog video camera described above can be overcome by employing a digital video camera.
  • An image filmed by the digital video camera is stored in a hard disk of a computer.
  • the video monitoring system employing the digital video camera also has disadvantages in that since the supervisor has to monitor a desired place in only a certain place such as a control room, there is a special restriction.
