A:Answer I can't answer your question.
I wouldn't waste my time with any TP-Link cameras. They will work fine at first, for a time. The minute something with your network changes, or if you disable them (and they go offline) you will NEVER be able to get them to connect to your network, ever again. They will persistently time out before you can get them to connect.
They are worthless. I had a set of the Pan & Tilt, as well as a set of the KC120 . This always occurs outside of the return window time frame. Stuck with $200 of worthless cameras.
