Well things took a turn for the worse. I replaced the connector (after I triple checked the wiring pinout). Plugged the camera into my NVR, which was on at the time. I heard an audible spark in the NVR, then smelled a burnt electronics smell, and heard a very faint oscillating sound, almost like a siren, but barely noticeable. I unplugged the camera. Then I checked the NVR and channels 1, 2, and 3 were all red dots, while the others seemed ok. Seems as if the camera has some sort of internal short, likely caused by the underwater connection. I assumed the POE power supply for channel 2 (which was the one my camera in question was plugged into) shared the same power supply with channel 1 and 3, so I moved cameras 1, and 3 to ports 7, 8, as those were the next open ones. I guess the camera is dead, I don't want to try plugging it in again.
I deleted the cams from the bottom pane of the NVR screen, and figured the NVR would recognize they were added to different ports, and move them back down to the bottom window. But the NVR isn't recognizing I plugged those in. And now a few other channels are showing red. Seems as if something really got messed up here. This whole thing is going from bad to worse.
In retrospect, I should have tried to plug the camera into a cheap POE switch, not the NVR port. A $40 switch would have been better to burn out than the NVR.
