Frame rate in conjunction with resolution and the number of bytes per pixel determine the amount of data that needs to be transferred and processed. For example, a camera with a 1280 x 1024 (SXGA) resolution at 30 frames per second (fps) and 8bits (or 1 Byte) per pixel will require

a data bandwidth of approximately 50MBytes/sec. This is below the PCI bus limit (~100MB/sec) and is within the capabilities of 1394.b or Gigabit Ethernet interfaces. Anything beyond 100MB/sec will require a frame grabberbased system with Camera Link® interface and PC with PCI Express® bus.
