Done. They told me, that the WZ500 does not support FTP.
More and more I come to the conclusion that the firmware somehow does not fit this camera at all. The idea behind it does not make sense to me at all.
I get the same feeling. I was on the verge of sending mine back when I found such poor firmware and support. I suppose you get what you pay for. Though now, with using Blue Iris and the config (above) for them, it's a decent camera with nice features. As long as I don't use the WebUI.
What were you trying to accomplish with the FTP upload? You can do a remote pull of the image using curl. (curl can be used on windows or macos too). But it wouldn't have any built in motion detection.
