Thanks, but no. IP cameras are explicitly right out. I said "secure rooms"
(no, no, these are not server rooms, "Server Room" requires serious
paperwork, etc....) but they *are* secure. We want no one able to connect
but us. And we've already got some perfectly good cameras that run BNC.
The reason I'm back to looking is the BT878 cards we have work fine... on
older, non-Dell servers. Firmware updates? What are those? A few years
ago, I tried tracking down the manufacturer... who got sold, and sold
again, and IIRC, sold again. I tried contacting the final owner, and got
no answer whatever.

So, we were looking for a newer capture card. These Blackmagic are PCIe; I
think the BT878's are PCI, or maybe PCI-x, and personally, I think there's
an issue in the chip Dell uses on their m/b to convert - it's a TI chip.

Anyway, thanks for the thought.

Oh, right... and we would not want a camera that we can't update the
firmware, and might be sending info back to China, or maybe it's being
used in a DDoS attack via the IoT....
