Norman, You are right - it is difficult to judge the reason for reboot after reboot. How often does it happen? You may also run http://<camera_ip>/hwmon.html and leave the page open to see the temperature. As it happens on two cameras it is not likely to be a hardware problem, so I would also suspect PoE switch. Easiest thing to try - run either from 48V direct power to the circular connector on the camera or use a single-port PoE injector that you received according to the invoice.
