To solve a problem that the cost reduction of a monitor system is disturbed by increasing the number of radars to be installed when a plurality of scan type human body sensing radars are disposed to envelop the inside of a wharf in the case of monitoring the inside of the wide yard adjacent to the sea like harbor facilities.
A millimeter wave sensor which detects a reflection wave reflected on a human body or on an object is provided to emit transmission beams along with the quay of the wharf, a visual line of an imaging device is disposed so that the transmission beams of the millimeter wave sensor pass inside a field of view, and the imaging device is turned so that the visual line is directed toward the presence of the human body or the object detected by the millimeter wave sensor.
