Very similar (and probably driver-compatible) cards seem to be sold under the names EverSecu ES-1612, EyeMax DVB1920, and Tibet Systems Progress DVR CS16. The latter's preexisting support in the kernel was how I managed to get this card working. The IDR X016S may also be compatible—the components on the card looks similar in layout.
The VideoSecu DVC1612 is a 16-channel PCI capture card with 4 Conexant Fusion 878A chips behind a PCI bridge. As suggested by its name, it is designed for security systems and comes with a CD containing a copy of the EyeONet DVR software.
The card has two VGA ports which are used for two VGA-to-BNC splitters (not real VGA). It seems that any of the 16 video inputs can be connected to any of the four Bt878a chips as long as the correct GPIO values are written, as already discovered by whoever added support for the Tibet Systems CS16.
Using the Card
My intention is to try to have working autodetection for this card, but that may not be possible. Use
card=131,131,131,131 as a parameter to the
bttv kernel module in the meantime.
