For those who are anti-cloud or want a 2-tier system for any good reasons, Been using this with several wyzecam V2 cameras for 2 years with no issues other than the cameras not being low light sensitive like the V3, otherwise the setup is pretty solid and fast.
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.
