Almost all trail cameras in today's market can process 32GB SD Cards. For some photographers, this might fall a little short of their desired storage, especially if they are using a high-resolution camera that produces images that need more space. For this purpose, some cameras come with 64GB compatibility. The physical size of the SD Card also varies. You need to make sure what kind of camera you have and whether it carries a miniSD, microSD or the standard SD card slot.
