Using existing analog camera/dvr system? - JOOAN TC-4208-US

I have an existing analog camera system in place with a JOOAN TC-4208-US DVR running the cameras. As they are analog I’m having trouble figuring out the best way to integrate it.

I can access it via web browser (IE only ewww it uses ActiveX https://i.imgur.com/C3cvVrf.png) but I can’t seem to find a way to include the cameras themselves via Home Assistant.

Any ideas?

This, but it doesn’t look very helpful

Yeah, those are IP cameras mine are analog so I can’t access them directly and I have to go through the DVR.
