I am looking for a firewire card for connecting 2 cameras. Will I be able to use a standard PCI-E card or will I need to look for one with one controller per port.... Most share a single controller voer multiple ports. I've had problems int eh past with multiple ports on one card, but this may have been a PCI card with limited system bandwidth.....
The cameras will be most likely 1280x1024 RGB cameras with 60FPS.
Cheers for any help forthcoming.
The cameras are actually monochrome, 8-bit not RGB (24-bit) and only go up to 30Hz.....
I mean theoretically a FW400 card should handle a 1024pixel x 1280pixel x 8bit x 30Hz (314 Mbit/s without overhead) picture no problem but adding a second camera will more than saturate the bus.....
Anyone know of a decent PCI-E FW card which has two ports with a seperate controller for each? Please?
I don't know any firewire cards that meet your specs, but it might work to get a firewire B card, then use cables that convert from firewire B to A. A single firewire B controller should be able to handle both cameras easily, but I am not a hardware expert so I can't guarantee it.
I strongly advise you to deploy a professional IEEE 1394a board for your imaging application.
National Instruments offers suchs interfaces for PCI, PCIe and PXI standards.
The card has 2 buses. You have 2 cameras. Thus, you will get maximum performance for each camera as long as you connect each camera to a port that uses one bus exclusively.
