A method for collecting sounds corresponding to surveillance images, comprising: when surveillance images are collected by a camera of a monitoring device, detecting whether there is a surveilled object making sounds in the surveillance images; if there is a surveilled object making sounds in the surveillance images, determining a sound acquiring device from a plurality of sound acquiring devices that has a signal strength of the sounds greater than a signal strength of the sounds collected by the monitoring device from the surveilled object; and controlling the sound acquiring device to collect the sounds from the surveilled object, wherein determining a sound acquiring device comprises: detecting whether sounds corresponding to the surveillance images collected by the monitoring device are smaller than a preset sound threshold; and if the sounds corresponding to the surveillance images collected by the monitoring device are smaller than the preset sound threshold: identifying (102b1) the sound acquiring device closest to the surveilled object making sounds among all sound acquiring devices bound to the monitoring device, and determining the identified sound acquiring device; or controlling (102b2) all sound acquiring devices bound to the monitoring device to collect the sounds from the surveilled object making sounds, and determining a sound acquiring device which collects a strongest sound signal as the sound acquiring device; or determining (102b3) at least one mobile device bound to the monitoring device as the sound acquiring device. when surveillance images are collected by a camera of a monitoring device, detecting whether there is a surveilled object making sounds in the surveillance images; if there is a surveilled object making sounds in the surveillance images, determining a sound acquiring device from a plurality of sound acquiring devices that has a signal strength of the sounds greater than a signal strength of the sounds collected by the monitoring device from the surveilled object; and controlling the sound acquiring device to collect the sounds from the surveilled object, wherein determining a sound acquiring device comprises: detecting whether sounds corresponding to the surveillance images collected by the monitoring device are smaller than a preset sound threshold; and if the sounds corresponding to the surveillance images collected by the monitoring device are smaller than the preset sound threshold: identifying (102b1) the sound acquiring device closest to the surveilled object making sounds among all sound acquiring devices bound to the monitoring device, and determining the identified sound acquiring device; or controlling (102b2) all sound acquiring devices bound to the monitoring device to collect the sounds from the surveilled object making sounds, and determining a sound acquiring device which collects a strongest sound signal as the sound acquiring device; or determining (102b3) at least one mobile device bound to the monitoring device as the sound acquiring device. detecting whether sounds corresponding to the surveillance images collected by the monitoring device are smaller than a preset sound threshold; and if the sounds corresponding to the surveillance images collected by the monitoring device are smaller than the preset sound threshold: identifying (102b1) the sound acquiring device closest to the surveilled object making sounds among all sound acquiring devices bound to the monitoring device, and determining the identified sound acquiring device; or controlling (102b2) all sound acquiring devices bound to the monitoring device to collect the sounds from the surveilled object making sounds, and determining a sound acquiring device which collects a strongest sound signal as the sound acquiring device; or determining (102b3) at least one mobile device bound to the monitoring device as the sound acquiring device. identifying (102b1) the sound acquiring device closest to the surveilled object making sounds among all sound acquiring devices bound to the monitoring device, and determining the identified sound acquiring device; or controlling (102b2) all sound acquiring devices bound to the monitoring device to collect the sounds from the surveilled object making sounds, and determining a sound acquiring device which collects a strongest sound signal as the sound acquiring device; or determining (102b3) at least one mobile device bound to the monitoring device as the sound acquiring device.
