Prompt PCI/PCI-E video capture cards?

Question

Video capture

Good afternoon!

I ask for help in finding and choosing a subject with high fps and 16 input channels.
Ideally, 480fps for all channels to work in real time, but a slightly less nimble option will do.
Working OS = linux
Software = zoneminder
In addition, an important condition is the fact that 2-3 cards can be supported at the same time, in order to eventually have 48 channels on one machine.

Chinese comrades create a lot of cards on good chips like GV 1480, VS2801 for example. But all of them are only for Windows.

Answer 1

2x Orient SDVR 7008e
You won't run 48 channels on one machine (full-frame, 25 fps) - the bandwidth of the motherboard is not enough.
Capture cards must be taken on the saa7134 chip in the pci-e slot.
I managed to launch 2 cards at full strength (16 channels in total).
I think another card can be made to work.
Instead of zoneminder, I recommend avreg.net
