TrueCam car cameras support microSDHC memory cards of various brands from a minimum capacity of 8 GB to a maximum of 32 GB.
For a memory card to handle the high bit rate required for high-quality, full HD video, we recommend a "Class 10" memory card.
We do not recommend buying poorer quality memory cards, such as from Aliexpress, which despite the designation "Class 10" often do not meet this condition.
