Abstract: The present invention relates to an intelligent central surveillance server system and controlling method thereof, which are capable of determining whether or not a preset event occurs based on a sensor sense signal and/or a motion sense signal and transmitting/receiving image information obtained in the occurrence of event through a serve-client system. The intelligent central surveillance server system comprises: a sensor unit configured to sense and transmit a sense signal; a camera unit configured to pick and transmit video information; and a digital video transmitter configured to determine whether or not a preset event occurs, based on the sense signal and/or the video information, and transmit first video information and first list information related to the first video information on the basis of the point of occurrence of event when the preset event occurs.
