Hello, I have two HDW5231R-ZE, but one of them have been self-rebooting by no reason a couple of days ago. The camera stay just a few seconds online. I already read Andy's topic about firmware versión 2.800.00000016 and its problems but I have not upgraded firmware since 2.800.00000010. I swapped PoE units, checked both network cables, umounted SDcards and the problem persists, just one camera works properly. After that, I applied a factory reset to the camera with problems, upgraded firmware to version 13 and 15, with factory resets between them and the problem persists. I am able to upgrade firmware (with config tool, web ui gets connection refused after some seconds) or change some configurations in a small time window between booting and restart, even to watch the main stream but I only can see a blank screen (weird). Could it be a hardware failure?
