IP cameras have a limitation for the maximum size (capacity) of a micro SD card. Most of the IP cameras work with 32GB cards.

The models that support up to 32GB micro SD cards are FI9821W V2, FI9821P, FI9821E, FI9818W V2, FI9826W, FI9826P, FI9831W, FI9831P,C1, C1 Lite, FI9821W V2.1, FI9821P V2/V3, FI9831P V2/V3, FI9821EP, FI9826P V2/V3, Fosbaby, Fosbaby P1, FI9816P V2/V3, FI9803EP, FI9853EP V1, FI9828P V2, C2E.

Some other models can work with higher capacity.

The models that support up to 128GB micro SD cards are C2, R2/R2C/R2M/R2D/R2E/P2, FI9926P/FI9936P/Z2, R4/R4M/R4S, FI9901EP, FI9900P, FI9900EP, FI9961EP, FI9928P, G2/FI9902P/FI9912P, G2EP/FI9912EP, G4/G4P/FI9901P, G4EP/QJ4.

An IP camera works with a specific type of table to write and read the files from a micro SD card, this is a little bit technical but to wrap it up, you must format the card using FAT32 which is a version the most used version of the FAT(File Allocation Table).
