Wyze V2 with Dafang-hacks have been super reliable in the past but these cams are now out of production with no reliable confirmation of this working with the V3s. I have been in the market for cheap 20-30$ cams like Wyze V2 with reliable setup like Dafang-hacks for a while but unable to find a good alternative yet.
I have been using wz_mini_hacks [1] on my Wyze V3 and have been pretty happy with it. Among other things, it has a “self-hosted” mode which patches the binaries running on the camera to no longer phone home to Wyze servers. I’ve been using it on my local network over RTSP with no issues.
I was not happy with wyze V3 but found reolink to work fine without internet, and Amcrest to be the best overall for being open and working without needing fancy software. I'd wholehearted recommend Amcrest except they don't have a very wide angle cam.
The issue with Amcrest and Wyze (and hundreds of other brands), is that they're just re-badging Dahua cameras, which are banned in the US. See https://ipvm.com/reports/ban-law for more information.
Of the lower cost and reasonably well-known names, the only brand that doesn't seem to be doing that is Reolink.
