I realize many are not concerned about open mics in the household. But Wyze recently increased the mic sensitivity of the V2 (and V3?) cams. Not because they couldn’t hear you muttering under your breath about something juicy. But because an (apparently) significant segment of the customer base requested it (to improve the 2-way conversation experience?)
So even if you are using cams externally but adjacent to living areas (mounted under an eave, for example) conversations in the home are now vulnerable to higher-clarity eavesdropping (and inclusion in cloud clips, etc.)
There is no hardware toggle on the V2 (and V3?) to disable the mic. Only a software setting. And that setting toggles ‘audio monitoring’ rather than disabling the mic - a co-equal or shared app user can toggle it back on at will.
