A network camera comprises a base clamped to a computer screen, and a camera body extended from a top of the base. The base is formed by connecting a front casing and a rear casing. Each of the coupling portions at tops of the front casing and rear casing has a semi-spherical groove. After the front casing and rear casing are engaged, the two semi-spherical grooves are formed as a round groove. The camera body is installed with a lens. An orientation of lens is adjustable. A bottom of the camera body is connected to a supporting arm of a signal transmission joint. Moreover, the camera body is formed as a universal joint in the round groove so that the orientation of the supporting arm is rotatable and the display frame shows a front view to present a wide eyesight.
