I'm sort of lost here, any help welcome.

Have a look at USB adapters. SD video is not that high bit rate,
especially if the adapter is compressing. No idea of the marketplace, although I have a $7 composite video USB capture that's probably
awful. BNC is just composite video I think - do they power from there
or external power?

If you have a lot of USB devices consider extra USB PCIe cards, but 4
behind a USB 3 hub is probably ok.

Today, there was a hint of sanity. I played around with the Zoneminder Monitors' Sources configuration, disabling the card inputs with no
camera, and other variations of the Source inputs. Briefly, I saw a live
image of the outside of the house, but when I tried to reproduce it on a different input, it would not, and I could not get it back on the
previously working one. But, I have at last seen the Source reference
for some tabs on the Console screen go green instead of red, albeit
it with a blue screen, and I have seen the ZM Log produce only "Capturing......." messages instead of a stream of pink-coloured
alarms, the wording of which means nothing to me. I will next
concentrate on trying to get the working image back, and hoping to
proceed from there.

Wish me luck!

After the recent problems with the ancient Ubuntu and Zoneminder installation, I thought about upgrading the PC, the old Dell is now 24
years old.
I have a new separate Swann system, but I cannot find how to extract
video from it, it likes Windows, not Linux.

After a few weeks of doing nit very much with this, I blew away all the
various OS versions that I had installed, and started from scratch.
So I now have a Clean install of Ubuntu 22.04, Zoneminder is again
installed and operating. It grabs the image from the CCTV camera in the
garage, as it passes through the router. I have not managed to get
anything yet directly from a camera connected to the Picolo card, usig
Linux commands, so I am returning to the Proprietary Euresys software
provided by the manufacturer of the Picolo card, Muliticam. I have
followed the labyrinthine instructions for installing and setting the
card and software up, and I freely admit that I am way out if depth, it
is aimed at people who do coding and programming for their living.
I have again come up against a compiling issue, and I know zero about
this.
When I initiate the Install procedure, it stops on a compiler
difference condition. I pate the relavant text:

Building glfm1
make[1]: Entering directory '/usr/src/linux-headers-6.8.0-49-generic'
warning: the compiler differs from the one used to build the kernel
The kernel was built by: x86_64-linux-gnu-gcc-12 (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0 You are using:

gcc is installed on the PC.

None of this is familiar to me, so I am asking for help in working out
what instruction(s) I need to issue to do whatever it wants to satisfy
this compiler issue. And is it indeed that simple, or is there
something else that is going to make this unworkable? After this is
working, I still need to get communication between the card and the PC.

Any help greatly welcomed! Euresys helped a little bit, then gave up
after admitting that they had found and were fixing a bug in the
software. They don't need little people like me, they work with big
industrial contractors who know how to code!

You can find out the actual version of gcc that you have installed by typing

gcc --version

With a distro as old as Ubuntu 22.04 you may find that successive
updates have landed with a newer kernel (compiled using a newer compiler
than you have) or a newer compiler (than was used to compile the
kernel). Short of switching to a fresh distro with no updates (which
*should* be consistent) or building your own kernel and drivers with the compiler you have I don't know a way to ensure consistency.

That seems to be saying that the make tool isn't installed. The easiest
way to get the full toolchain installed is to install the metapackage
called "build-essential".

Thanks for the response. The deeper I get into this, the
more complicated it becomes. When I installed Zoneminder into the
original ver. 8.04 machine, it was simple: Follow a script, edit a
conf. file for the card, re-boot and start operating. This just goes
from nothing to another nothing. and the old Pentium 111 PC using ver.
8.04 is still working with Zoneminder!
My present options seem to be:
Abandon using the new PC with its own Zoneminder setup (includes
removing the video input card. Maybe I can re-sell it!); continue to use
the old PC, on which I can still view screens and operate the setup
from other PCs; try again to get the Swann system to talk to Ubuntu, but
as far as I can see that is not a common concept.

But I have wasted enough time on this new PC and Zoneminder to say:
"Enough is enough".
Thanks for confirming that what I am trying to do is pointless!

I didn't say 'pointless' ... and there may be easier ways through the
process than I know ... but it does require that everything use
compatible versions of all the tools, and the easiest way to ensure compatibility is to be consistent.

I take it you have seen this:

https://zoneminder.readthedocs.io/en/latest/installationguide/ubuntu.html

It seems someone has provided a prebuilt binary in a PPA, which you can
chose to trust and just install.
