Questions about EZVIZ HB8 incl. solar panel

You need to be especially careful because the ports may be different! The best thing is to buy the version that includes the camera with battery and its panel, that way there's no risk. I bought two cameras with batteries only. I ordered two panels to connect them to the camera and then, lo and behold, I didn't get the same USB port. That's all I can tell you.

Hello There is a separate single piece of solar panel. I bought the one with the solar panel and ordered an additional solar panel in case the existing one becomes defective.

I don't quite understand your question. This camera is normally via wifi and panel is for battery charging so it has power supply!
