Own four Wyze v2 cameras. Totally awesome. But the one we use in our occupied house always has the microphone on. So our kids, with whom we share the feed for security purposes can ALWAYS hear what we are doing in our house. We have the sound off (the speaker icon has a line through it) but it makes no difference. The camera is aimed outside so we don’t need the sound at all. But how do I turn off the microphone so it stays off?
