You can record video from the microSD card when you are playing it back within the Wyze app, but you have to do this in real time ( no faster ) and it can be fraught with issues if your connection is less than perfect. So this is easiest for short clips that you want to save.

The videos will be in the /record folder on the microSD card.
There will be subfolders named for each day within this folder, and subfolders within each day numbered for each of the 24 hours.
The actual video clips are one minute long MP4s numbered for each minute.
