MASS VIDEO RECORDING SYSTEM FOR MONITORING CITY

The present invention relates to a mass video recording system for monitoring a city. The mass video recording system comprises: a plurality of cameras installed to capture images of areas to be monitored of the city; electrophotic conversion units converting image information output from the cameras into optical signals; a photoelectric conversion unit converting the optical signals transmitted from the electrophotic conversion unit into electrical image signals; and a control unit controlling a recording unit to record the electrical image signals output from the photoelectric conversion unit. The electrophotic conversion units are provided to correspond to the cameras, respectively. In order to output sequentially, to the photoelectric conversion unit, a signal output from each of the electrophotic conversion units, an optical switch unit connected between the electrophotic conversion units and the photoelectric conversion unit is provided. Such a mass video recording system for monitoring ...
