Depending on your specific Wyze cameras, you can literally make them local only and never need to send back to Wyze servers. https://robsears.com/wyze-cam-v2-rtsp-iptables/

Edit: actually, looks like it’s officially supported for v3 as well. https://support.wyze.com/hc/en-us/articles/360051619871-Does-Wyze-Cam-v3-support-RTSP

So yeah, completely different ball game. If Wyze ever does anything you don’t like you can just turn your cameras into cameras you control completely.
