摘要： There is provided a domed monitoring camera apparatus allowing reduction of a shift in focus dependent on a variation in optical path length caused by a dome cover. The domed monitoring camera apparatus (1) includes a monitoring camera (3), a dome cover (5) which covers the monitoring camera (3), and a camera controller (25). The camera controller (25) functions as an adjustment unit which, when the dome cover (5) is attached, adjusts the focus of the monitoring camera (3) with the cover attached to correct a variation in optical path length caused by the dome cover (5). The camera controller (25) adjusts the focus of the monitoring camera (3) with the cover attached according to an optical path length affecting cover parameter which represents a dome cover character relative to increase or decrease of the optical path length of the monitoring camera (3).
