The first thing I want to cover is what it means to format a microSD card in the first place. Basically, when you format the card it blanks the data already existing on the microSD card, removes corrupted data that would prevent use, and sets the card to a particular format so that devices will be able to use and recognize it.
We use FAT32 because it has a fast and stable transfer rate for continuous streams of data. Many cameras use FAT32 as their default because you don’t risk losing data over longer periods of time. It has a limit of 32 gigabytes and that’s why that’s the maximum microSD card that we support. There is another format, called exFAT, that is pretty similar. It is for anything over 32 gigabytes but it is not as stable for continuous data streams over long periods of time and does not transfer as quickly. This is why many companies, including us, don’t use it. If you put an exFAT formatted card into your Wyze Cam the camera MAY recognize it but the less stable nature of the formatting may cause data loss or loss of camera recognition over time.
Wyze Cam now has the power to format a microSD card! To do this, select the Wyze Cam you want to use from the Devices tab, open up Camera Settings, and then go to Advanced Settings. At the end of the microSD card settings, there is an option for “Format SD Card.” Just press the “Format” button to start the process. What this will do is have Wyze Cam format to FAT32 and remove pre-existing data. This is useful if you use a microSD card that has already been used and is not recording properly. Please note that your Wyze Cam has fewer resources than your computer so it will take longer to format.
