How to pipe 4 digital cam streams into 4 analog PAL/NTSC

[robejrm]

Hi!

I need to put 4 ip cams streams into a legacy suiveillance recording system that has the usual analog inputs.
Do you know any Linux working hardware that could do that? Should I use 4 graphics cards with TV-out support?

Any other way of doing that?

Let me know if you don't understand what I am trying to get.
Thanks in advance,
Juanra

that would be one way of doing it, but tbh it probably isnt the best. There are Ip converter units that turn video into ip and back, perhaps one of these might help if they are compatible. Alternativly just add a pal camera adjacent id say this would be more cost effictive, as bottom end (granted not very ggod) pal/ntsc cameras are quite cheap.

But basically id look at
