Are your amphenol cables secure? Is your system mounted somewhere that may experience undue vibrations (i.e. a door being slammed, don't laugh I've seen a system mounted on a door!) Have you experience any power issues. I know the system is hooked to a UPS but I've seen batteries in these units fail. Maybe after hours you could test this by unplugging the UPS and see if it actually keeps the system running and for how long. Does it keep it running for the rated amount of time. Just some ideas. Keep us posted.
Thanks,
John
