An internet-protocol camera device includes a lens module and an image pickup module. The lens module guides light to the image pickup module. The image pickup module includes a metal housing, heat generating electronic devices received in the metal housing, heat sinks received in the metal housing, and heat dissipation plates. The metal housing includes a first inner side surface, a second inner side surface, a third inner side surface and a fourth inner side surface connected end-to-end in that order. The first inner side surface faces the third inner side surface. The second inner side surface faces the fourth inner side surface. The heat sinks are mounted on the corresponding heat generating electronic devices. The heat dissipation plates are mounted on the first inner side surface, the second inner side surface, the third inner side surface and the fourth inner side surface.
