Has anyone done any tests on what power the H7 needs to function?

The power "brick" indicates that it outputs 2.5A @ 12v, I was wondering if it would be possible to power it via PoE, using a 12v injector/splitter, something like this - https://www.ebay.co.uk/itm/POE-Injec...R/152968149007 would work? Max power seems to be about 2A via the injector, but I guess that would ultimately depend on the cabling used and the run length. But was wondering if anyone had powered one of these boxes via PoE injector/splitter?
