Re: Video Capture Card



Have a look at this article as it seems to indicate that there are drivers for the card's chipset. You may have to build your own kernel though in order to support if the driver is not already a module. 

It seems pretty straight forward though.

Does anyone know how to get a SAA7146 based video capture card to work

02:0c.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)

This was an existing system about 7-8 years old that the hard drive
went bad and we lost all the software and such to run the system.  I
was told I could have a few days to try to come up with a Linux (open
source) solution. I would like to eventually use Zoneminder (unless
someone has a better solution) to control the cameras and record the
video.  But right now I am stuck with hardware issues.

Anyway, if you have a recommendation for a card that you know works,
that would probably be best.  The cameras currently all come in on
cctv with bnc connectors -- to a bnc-to-vga connector into the board.
