Digital Watchdog, had some relatively affordable HD over coax (not sure
about 4K) systems last time I looked.  They even worked (back then) with
other MFGs cameras.  You just had to have the same make, model, &
resolution of camera (I suspect format nuance) for pairs of camera.   I
installed a few DW DVRs and they were ok, but they had the typical tech
company attitude of fail fast - fail often.   I often had to update DVRs
in the field to get them to work properly.  I never used their NVRs.  I
used that Chinese company that you guys were complaining about not all
that long ago for X.X-MPs over Cat wire.  They were much more
restrictive, but I suppose you know that.
