Hi, folks,
I'm still trying to find a video capture card that won't crash Dell servers, and ran across a Blackmagic BDLKDUO2 DeckLink Duo 2. It claims to support Linux. I'm also seeing, in the few non-Blabkmagic or sales pages I can find, that they like "binary blobs". I also haven't been able to find anything about o/s or library requirements.
Has anyone run across these cards, or know anything at all about them? All we're doing with them is running a few video cameras in for surveillance of our secure rooms, no audio, nothing fancy, with the motion package reading the input.

I would use tcp/ip network cameras, ideally with PoE to simplify running power to them. plus cat-5 is a lot easier to run than coax or HDMI.
I've got one of these, works well enough. https://www.amazon.com/TRENDnet-Megapixel-Resolution-monitoring-TV-IP320PI/d...
I'm not using it, but these should work great with ZoneMinder or most any other video surveillance/recording package.

<snip> 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....

thats why you would put them on an isolated network attached only to a dedicated PoE switch, and a 2nd NIC on your video server.
but whatever. these BNC cameras, are they SD (480i) analog composite video or HD/SD cameras with digital single-link SDI ? that blackmagic card is for SDI digital cameras. https://www.blackmagicdesign.com/products/decklink/techspecs/W-DLK-31 nothing there about NTSC/PAL Composite analog input.

Blackmagic support is sketchy at best.
I'd have to say they allegedly support Linux.
I got one of the USB 3 units that claimed Linux support and was told "nuh uh" with not even an attempt to find a way to make it go.
Find something different.
