Which CCTV systems will interchange with a Dahua system?

Something like an intel i350 dual nic will work with almost anything. I think these usually take an x4 pcie slot, but you can find other nics that take an x1 slot. I’m surprised your old hp tower doesn’t have a suitable pcie slot.

Yes, let us know how it comes together.

I had a look. 3 PCI slots. It's too old for PCIe.
