Storage: FLIR FX microSD card file format
The FLIR FX camera requires a microSD card (included) for saving recorded video files, images, and firmware update information. It does not require a microSD card for live viewing, setup, and settings unrelated to recording. If you are replacing the microSD card, it must be formatted with the FAT32 file system:
