Just thought I'd share my recent experience with one of the three 507s I bought for my vacation pad. I gave one to a neighbor up there, and he promptly hooked it up to 48V active PoE. It fried something. The red LED on the PS now just blinks when the camera is connected. I emailed the seller via AE, and they were supper helpful. They sold me a replacement "main board", which they said would have certainly fried with that over voltage. The board, with shipping, was USD29.00. It arrived a few weeks later, and I replaced it without issue. Unfortunately, as soon as the wiring harness from the camera/lens module was plugged into the main board, the PS would get overloaded again. I reached out to the seller, and they suggested replacing the camera/lens module... Get this... US76 incl shipping to US. Un-real. So sent them $80, and a couple more weeks, it arrived. I replaced it, and bingo. I now have a fully functional camera again. These things are so easy to take apart, and so modular, as long as parts are available, I feel pretty comfortable with self-service.
FWIW, here is a recent time-lapse capture from up at the cabin...
