IP cameras are Closed-circuit television (CCTV) camerasthat use Internet Protocol to transmit image data and control signals over a Fast Ethernet link. As such, IP cameras are also commonly referred to as network cameras. IP cameras are primarily used for surveillance in the same manner as analog closed-circuit television. A number of IP cameras are normally deployed together with a digital video recorder (DVR) or a network video recorder (NVR) to form a video surveillance system.
The terms IP camera and network camera are most commonly used to refer to surveillance cameras with a Fast Ethernet interface. In this context, the term IP camera does not include GigE vision camera, which is a machine visioncamera with a Gigabit Ethernet interface.
