Disclosed is a dome-shaped PTZ surveillance camera. According to an aspect of the present invention, provided may be a dome-shaped PTZ surveillance camera comprising: a fastening frame; a pan frame which is coupled to the fastening frame so as to be rotatable around a first axis of rotation; a tilt frame which is coupled to the pan frame so as to be rotatable around a second axis of rotation perpendicular to the first axis of rotation; a motor unit which drives the pan frame and the tilt frame; a hemispherical sight window which is coupled to the fastening frame and which covers the pan frame and the tilt frame; a zoom camera which is coupled to the tilt frame; infrared lamp units which are coupled to the tilt frame and which are spaced apart from the zoom camera in the second axis of rotation; and a hemispherical shielding structure which is coupled to the pan frame, which comes in tight contact with the inner surface of the hemispherical sight window, in which a first opening is formed in a photographing path of the zoom camera, in which second openings are formed in light emission paths of the respective infrared lamp units, in which separation portions configured to come in tight contact with the inner surface of the hemispherical sight window are formed between the first opening and the second openings, and in which shielding walls configured to protrude from the separation portions are formed.;COPYRIGHT KIPO 2017
