PURPOSE:To provide a monitor device which applies the images, can freely move the monitored and monitoring points and also can eliminate the need for addition of an image branching device, etc., when the monitoring jobs are performed at plural points. CONSTITUTION:A radio transmission device 11 is provided at the monitored side 1, and a radio reception device 21 is provided at the monitoring side 2. Thus a radio transmission line is formed. Then the image information received from a camera 13 of the side 1 are modulated and coded by a modulating/coding device 12 and sent to the side 2 via the radio transmission line. At the side 2, the received signals are demodulated and modulated by a demodulating/ modulating device 22 and displayed on a monitor 23. Thus the movement is facilitated to the side 1 or 2 or between both sides by means of the radio transmission line. Then the signals can be received at a time by plural reception devices of the side 2 with no addition of any device. |
