Observation system and method having auto-sensing/filming function

PURPOSE: A monitoring system and a monitoring method are provided to three dimensionally photograph a noise area by using 3D sensing data. CONSTITUTION: A camera(10) transmits images of 3D zoom out state and 3D zoom in state to a monitoring server(60). A roller attached to a camera moves in a rail(20) for moving the camera. A plurality of noise sensors(30) transmit 3D sensing data to a wireless sharing unit(40). A monitoring server stores images and analyzed position information and uses the storage data as assistant data of news.
