I’ve had a Ezviz home camera for years. At some point, the RTSP stream in HA stopped working entirely, and I didn’t think much of it.

A week ago I decided to reset the damn thing as the verification password on the bottom didn’t take in HA, only to realise that the setup flow on the app just didn’t work for configuring WiFi, and there was no feedback at all, or any support articles surround it. I’d given up for a while, plugged in ethernet temporarily instead and tried again.

The correct WiFi setup procedure was hidden away in some menu, which I couldn’t even remember using last time (showing a QR to the camera and it silently taking the credentials). Only then I found out about how you can view the camera in the app in LAN View Mode, pray it accepts your verification password without spitting random HTTP errors, and there the RTSP toggle was to be found. I do have the stream back in HA, but my god that was a pain. I’ve been at it for hours at that point.

Was it worth it? No, I would’ve thrown it out the window way sooner - but it beats having a paper weight for a camera which used to work fine an hour ago.

Okay so not exactly zero, but until a heavy hitter like Samsung won’t even consider, worldwide adoption is going to be low - their flagship just stuck with Qi 1, even though the standard existed for about two or three years at this point.
