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.

Doe these "professional" IEEE cards have full 400MBit per port, or is the bandwidth shared over all ports....
If shared, I fail to see the huge advantage over a "nonprofessional" card.

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.

The Q was meant more for the "Official" NI response, but that's cool info too.
Any idea where I get pricing for one of those cards? The website doesn't offer any pricing info.
