Abstract
A supervisory system in which a plurality of supervisory points (1) to (N) are monitored one after another by a monitor camera. The supervisory points are switched at random based on random numbers. A period of monitoring each supervisory point is set at random based on the random numbers. When random monitoring is carried out, it is controlled in order not to select the same supervisory point in succession.
