Abstract

An integrated Internet camera includes, as embedded components contained within the camera body and controlled by a microcontroller, at least a network interface device for connecting to the Internet, a transport control device for packetizing according to Internet protocols, a file transfer device for communicating with a destination user directory on the Internet, and a transmission initiating device for initiating the connection and transfer operations of the file transfer device and transport control device. The network interface device may be a modem, network adapter, or adapter for connection to the Internet.
