ONVIF support is surprisingly spotty on low-end (<$100) IP cameras, especially wifi ones. Even if a camera claims to be ONVIF compatible, you should really check for a certification at [0]. Even for RTSP, there's often something stupid like the camera implementing 90% of the protocol except it never responds to OPTIONS requests. And fun fact, VLC no longer supports RTSP on Debian-based distros due to licensing issues [1].

RTSP completely lacking on battery powered devices which they don't clearly state anywhere. In fact the battery/solar powered units are practically useless as there is a huge delay in footage after detection so you will miss people/events.

  Streaming video is fairly power intensive, the typical battery powered camera could not sustain more than a few hours of streaming without resorting to a prohibitively large battery pack.

    Author here! Some very smart contributors have helped decode another layer of the Baichuan protocol - I actually missed the "media wrapper" because it happened to work without removing those headers from the video stream - as well as the UDP protocol variant, so it is technically possible to stream from battery cams. It does drain the battery unless they're externally powered.

  There was an ONVIF/RTSP battery camera I wanted, but nobody seems to have on the second-hand market... Netgear actually sold a rebranded/reflashed Arlo system as the FlexPower line with a special base station and reflashed Arlo cameras. The base did the magic that let the connected wireless Arlos act as ONVIF cameras in a DVR.

One of the worst cases of this that I've seen recently is TP-Link's Tapo, which does seem to support ONVIF to a usable extent, but it is impossible to set up the camera or move it to a different wifi network without using their stupid mobile app that requires a cloud account. It works fine offline after that.
