I have seen many similar posts relating to wired stick-up cams either going offline or displaying low-battery warnings.
I have two wired cameras which are no longer appearing in my dashboard (doorbell is fine). This is the third time this has occurred.
My wifi and power-supplies are confirmed as good (unaltered)… And the doorbell seems happy enough.
The low-battery issue is interesting - when I setup the cameras there was no option to specify wired supply in the app. (even though there is no battery present).
I noticed a solution posted 5/15/2020 which seems to show a workaround of adding a battery to the cameras but that this is no longer needed. (same post, 6/6/2020).
Can someone confirm that if I go up a ladder for the third time and reboot these devices, there will be a fully supported mains-power operation mode…? It seems there is a serious bug here.
