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 estab-lishment 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 occur-rence of the Particular event is stored in an image memory on the basis of the output of the sensor indica-tive of such sensing. After the establishment of the communication path between the transmission and receiving stations, the stored video is transmitted to the receiv-ing station to thereby ensure monitoring a truly required video.
