Abstract
A communication path is established, only when monitoring a video signal on an object is required, between a sending station which acquires the video signal and a receiving station which monitors the acquired video signal through a display or the like. Usually, the video signal is monitored delayed by a time taken for establishment of the path. In the video monitoring system, a sensor senses the occurrence of a particular event to be monitored, the video of the object existing at the occurrence of the particular event is stored in an image memory on the basis of the output of the sensor indicative of such sensing. After the establishment of the communication path between the transmission and receiving stations, the stored video is transmitted to the receiving station to thereby ensure monitoring a truly required video.
