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.
