assuming the camera has rca out jacks, you can get a rca to hdmi adapter box for less than $20. If you computer doesn't have hdmi capture they also make rca to usb boxes as well (I don't think the cables from rca to usb without a chip in it will work but I might be wrong). Then OBS can record it
They also make little devices that take a usb thumb drive and have a little screen for preview, then you don't even need to tie up a computer while doing it.
Just hit record on the box with the usb stick and hit play
on the VCR and set a timer to come back in an hour or two.
