I have several Wyze Cam 2 devices and I have an SD card in both, and set for continuous recording. If I take out the SD card, is the video constantly streamed up to cloud servers that I can access via the Wyze application?
You can live view the camera via app anytime that it is connected to the internet. You can utilize the cloud recording (free service or camplus) anytime the camera is connected to the internet. Cloud storage and local storage (sd card recordings) are completely Independant if each other, you can have one, both or neither at anytime.
But the cloud storage is never continuous - it records only for the perceived duration of a motion event (or 12 seconds without CamPlus service).
