And as promised, this is what support had to say (very similar):
" Thanks for reaching out to us! I’d be happy to address your questions!
A. Does the Wyze Cam auto-detect and choose the 2.4 GHz network all by itself or do I manually set it up that way on the cam/app side? Or do I need to block the 5GHz option in my home to make it work properly?
You will need to manually choose the 2.4GHz network when prompted to connect.
B. On the other/receiver end, do I need to be on a 2.4 GHz network when accessing the Wyze app for settings, watching recorded footage and/or getting alerts on my device(s)? I sure hope this only matters on the cam side!
You can view it from your other network and remotely! However, for setup, you will need to be on the 2.4GHz network.
C. Either way, what exactly happens when the WiFI signal drops or has outings? Will it still motion-detect and record? My assumption would be that it still detects but only records to the card (if installed/attached) but not to the cloud; and I wouldn’t get an instant alert. Correct?
If there is an SD card present, you should still be able to record if the signal drops or blanks out. Without an SD card, an outage may not allow the Events to record or be detected.
If so, would the alert for the “missed” event still come in later when WiFI picks up again – and would the recording still be uploaded to the cloud at that point (in retrospect)?
I would say this would be a case by case situation. With a WiFi interruption, the actual Event may not be recorded or detected properly so it could also not upload. The best method is to have a microSD card installed and Events can be recorded directly to the card.
Hope this helps! Have a great day and don’t hesitate to contact us with any further questions or concerns!"
