I have used three wyze cams but only for pointing outside or to monitor plant growth. Here is an HD timelapse of a Monstera Deliciosa I made with one: https://youtube.com/watch?v=0NH2t1fJL9w&feature=emb_title

The first thing I do with a wyze cam is physically remove the microphone, because it can only otherwise be turned off in software which is configured in the cloud.

I'd consider using them with the OS firmware change, but hadn't thought of also running them on an independent network.
