greetings,
I'm not sure about the quattro card, but you should be able to find
other bt8x8-based cards with multiple inputs (I'm not extremely familiar
with model names and so forth, but I do use a PC/104+ bt8x8 card with 4
inputs, so I'm sure similar cards exist for PCI). These cards typically
mux the video inputs, so you can't capture from multiple sources
simultaneously, though you can rapidly switch back and forth between the
inputs and get a reasonable frame rate. Though what's reasonable for me
might not be reasonable for you, of course. If you want to maximize the
frame rate on a single card, then you need to synchronize the signals
of the various inputs.
As for using multiple cards in one system, I'm fairly certain that the
bttv driver can share interrupts, so irq availability may not be as much
of an issue as you think.

First of all I would like to apologise for my poor english. I will try to

I am very new to V4L and would like to use it in a shop to record the
pictures from several cameras.
In this list archive, i saw a post talking about a card from ids
(http://www.ids-imaging.de/html/ids/gb/gb_ids_Falconquattro.html) with 4
inputs. Did someone managed to use it under Linux or should i use several
cards ? The problem in multiple cards is the availibilty os pci prots and
irq's...
Thank you.
