Abstract: The present invention relates to a monitoring apparatus and a controlling method therefor. The present invention comprises: a device body mounted in any one side of an object having a front side and a back side; at least two cameras, equipped in the device, for receiving images of the direction in which the front side of the object is directed and the direction in which the back side of the object is directed; a sensor unit for sensing the object and the situation of the object's surroundings; and a control unit for driving at least one of the cameras in an imaging standby mode when a target object approaches within a predetermined distance from the object, switching the at least one camera to an imaging activation mode when a preset situation occurs as a result of the sensing of the sensor unit, and performing functions corresponding to a currently occurring situation by using at least one of the images received from the at least one camera and sensing results from the sensor unit.
