Abstract
A security monitor system is designed to transmit video signals from a plurality of video information sources via a common transmission line. Video information from respective video information sources is scanned at given timings to check the monitoring areas in a given order. An automatic recognition may be facilitated in the security monitor system for detecting substantial and noticable movement within a picture derived from the video information from each of the video signal sources. Therefore, the security monitor system is inexpensive and satisfactory for monitoring a plurality of monitoring areas and is satisfactory for recording video information of a variety of monitoring areas, when movement in the picture of one of the monitoring areas is detected, by means of a video tape recorder or other appropriate recording means.
