Intelligent central surveillance server system and controlling method thereof

The present specification relates to an intelligent central control server system and a control method thereof which transmit and receive image information photographed in case of event occurrence through a system of server-client concept mutually by judging occurrence of a pre-established event on the ground of a sensor sensing signal and/or a motion sensing signal. For the purpose of the present invention, the intelligent central control server system according to the embodiment of the present specification includes: a sensor part sensing a sensing signal and transmitting the sensing signal; a camera part photographing and transmitting image information; and a digital video transmitter judging occurrence of the pre-established event on the ground of the received sensing signal and/or the image information, and transmitting first image information and first list information related with the first image information by referring to the event occurrence time when the pre-established event occurs.
