The present invention discloses a surveillance system and a control method for marine aquaculture crime prevention reflecting the difference in the number of tides.The monitoring system of the present invention includes a target body (a container for storing sunlight, a solar photovoltaic heating plate for red tide sensor, a light emitting buoy) installed in the farm to measure the height of the sea surface according to the difference of the tide interval alone； A general video camera that acquires an image of a farm monitoring area and has a pan / tilt / zoom driver； A thermal imaging camera having a pan / tilt driver that obtains a thermal image for a farm monitoring area and is independently driven with respect to the general image camera； A laser distance measuring unit mounted on the thermal imaging camera and measuring distance information on the photographed object or the target； And a controller for controlling the camera and the equipment on the basis of the image captured by the general video camera or the thermal camera,The control unit stores the peripheral terrain scanned by the surveillance area of the farm, as a surveillance map, and displays a virtual appearance line (Virtual Line), which is set to the pan / tilt angle of the camera, And determines whether or not an event appears on the photographed image coordinate value (X, Y) at a distance (Z) of the laser measuring instrument to a subject appearing in a virtual appearance detection line (Virtual Line) (X, Y, Z) of the specific target object of the target object and the stored initial position point (X, Y, Z) To automatically acquire and analyze the surveillance image while automatically correcting the surveillance area in real time considering the difference between the tides only and to monitor the subject in case of an event, And more particularly to a surveillance system for intruder detection.본 발명은 조수간만 차이를 반영한 해양 양식장 방범용 감시 시스템 및 제어 방법을 개시한다.본 발명의 감시 시스템은 조수간만의 차이에 따른 해수면의 높이를 측정하기 위해 양식장에
