[Problem] To provide a control apparatus that is capable of continuing monitoring even when an environmental change causes fluctuation in the coverage area of a sensor. [Solution] This control apparatus is provided with: a coverage area prediction means 1; and a control means 2. The coverage area prediction means 1 predicts, on the basis of the measurement result of the environment of an area in which an object is to be detected, a coverage area that is a range in which a stationary sensor for detecting objects can carry out measurement. The control means 2 determines the position where a mobile sensor for detecting objects is to be disposed, and controls the mobile sensor, on the basis of the coverage area predicted by the coverage area prediction means 1 and the probability that the object is present.
