A video communication device includes a video communication device body; a camera fitted to the video communication device body to record images of an object; at least one detection unit fitted to the video communication device body to detect the object according to a predetermined condition; and a camera rotation angle adjuster fitted to the video communication device body to adjust a rotation angle of the camera according to detection data from the detection unit so that the camera automatically tracks a position of the object when the object moves. The moving object can be located through a detection unit, such as a voice sensor, a codec, a color sensor and an IR sensor, and be automatically tracked by suitable adjustment of the rotation angle of a camera. A wide angular field is ensured and video telephony quality is improved.
