Claim Text:
1. A monitoring camera comprising: an imager having a zoom lens; a turn table that moves the imager in panning and tilting directions; an image processor which subjects an image captured by the imager to image processing for identifying a tracking target, and generates tracking information including information about motion of the tracking target and pan, tilt and zoom information; a tracker unit which tracks the tracking target by controlling the zoom lens of the imager in accordance with the zoom information generated by the image processor and controlling the turn table in accordance with the pan and tilt information generated by the image processor; and an intrusion detector which determines, during tracking of the tracking target by controlling the turn table, based on the information about motion of the tracking target generated by the image processor, whether or not the tracking target intrudes inside of a preset area from outside, and outputs an alarm only if the tracking target intrudes the inside of the preset area from the outside, wherein, if tracking of the tracking target starts from the inside of the preset area and the tracking target remains in the preset area, the intrusion detector does not output the alarm, wherein, if tracking of the tracking target starts from the inside of the preset area and the tracking target moves to the outside of the preset area, the intrusion detector does not output the alarm, wherein the image processor has at least a search state, in which it is determined whether or not a moving subject is a person, and a tracking state in which the person determined in the search state is tracked, and wherein the intrusion detector outputs the alarm when the image processor is in the tracking state.
