A control apparatus includes a determination unit configured to perform detection processing for detecting a volume of a sound obtained by sound obtaining unit corresponding to imaging unit, determine whether the volume is not less than a threshold, and execute volume determination processing for outputting a determination result, a change control unit configured to perform first change control for changing an imaging direction in the imaging unit, and a control unit configured to control to change control associated with the volume determination processing when the first change control is executed by the change control unit and the second change control is executed by the change control unit, so as not to set a state in which the first change control is performed, upon execution of the second change control.
