FIELD: physics.
SUBSTANCE: in a method for capturing sounds corresponding to observation images, when the observation images are collected by the monitor camera, it is detected, whether there is an observable object creating sounds in the observation images. If there is an observed object creating sounds in the observation images, the sound receiving device is determined that satisfies the present condition that requires that the signal level of the sounds captured by the receiving device from the observed object is greater than the signal level of the sounds captured by the monitoring device from of the observed object. The sound receiving device is controlled to capture sounds from the observed object. Thus, the present disclosure can solve the problem that the monitoring device can not clearly capture sounds from the observed object, which is relatively far from the monitoring device.
EFFECT: increasing the level of the signal captured by the sound monitoring device from the observed object.
