Do they all run off one 12v power supply ?
I would usually look at the power supply here too.
...Or is it the monitor? How does the "ripple" change when you swap between single camera view and quad view? Also, try changing the monitor power supply (if it's an LCD monitor with a separate psu) if you can. We spent 6 months trying to track down a ripple problem that turned out to be a dying monitor psu...

As previous post.....check connections as you are getting EMI currents induced in coax......
You may also want to replace the power supply as it could be "noisy"..
Try to avoid running 240Vac cables near to coax/12Vdc cables....
