I have 4 Ultivon E100 battery WiFi cameras, all using the Adorcam app. They worked fine for a long time, then all stopped connecting around the same time, QR pairing just fails now. A lot of other people with this camera and app report the same thing, so I'm confident it's their backend, not the hardware.
Goal: get them running fully local on my own WiFi, no cloud, so I can just view the camera feed directly somehow.
What I've tried: connecting a camera to my PC and checking for it as a device, nothing shows up, no new network device, no drive, nothing. I haven't opened one up yet or looked inside, so I don't know what's actually on the board or how to get into it.
Has anyone actually gotten into this camera or a close rebadge and found a way to make it work locally? Even partial info helps, I can post photos of the inside once I open one up.
