OK; looks to be supported in Linux.
Not sure on the Wintel side. Try Blue Iris.
The reason probably that there isn't support is that today most of the older style (32 bit or 64 bit) multiple port capture cards only really support SD video streaming. The bottle neck is the analog output of the video camera to the capture card limit of 640X480.
The above noted best you can do with the card though is SD video; so it'll be a bit faster at 64 bit; but it'll still be maxing out at 640X480 streams.
Personally and less work would be to go to IP cameras. You can experiment with the low end cheap SD IP cameras ($40 now) connected to say Blue Iris staying on the wintel side of things.
Here I am still using ZM. It does have both Analog and IP cameras connected.
As your bottleneck is still the limit of the multiport capture card and you want to continue to do this then I would purchase an 8 port BT8X8 8 chip Kodicom 8800 clone. You can buy these now for some $30.
Attached are three streaming SD capture pictures. Two are analog streams using a Kodicom 8800 32 bit card and the other is same sized stream using an IP HD camera streaming with RTSP at the same size. Not the difference in picture quality with the same resolutions.
Personally too I would recommend building a security DVR box with multiple camera streaming and making that a separate box. You can do this for free using either Linux or Wintel software these days. You can purchase
I would also recommend not combining a security DVR server and automation software server (like Homeseer).
Maybe trying this with a separate VM might work.
Here I am doing a very slow transition. The current Optex combos outside have newer camera boards / lenses. I am replacing these with combo HD IP and analog output boards such that I can do analog captures and digital captures from the same cameras. All of my outdoor cameras are wired for legacy and IP such that switching them is no big deal.
