All is OK!!!
I ordered 2 of these cameras. One connects to my NVR and has an IP address, but unfortunately only shows a black picture. (this is replacing another camera which I purchased from Besder, but only lasted a year til faulty) The second camera was dead on arrival. I have tried powering from POE, and also from local DC power supply. Although they are the cheapest camera, but they are a waste of money. And don't even talk to seller - they are of no help. Spend another $15 somewhere else and be satisfied!
