The IEEE1394, also called FireWire, is a modern plug-and-play interface between PC and camera (or other peripherals, up to 63 at a time) and allows the connection of several cameras to one board without the need of a frame grabber. It is sort of a high-speed serial memory bus capable of operating at 400 MBit/s. 1394 refers to the total bus bandwidth. The bandwidth being 30 times larger than that of USB makes it more suitable for the high-speed data transfer desirable for digital imaging.
