We recommend using Class 10 microSD cards for optimal performance and reliability.
Using a lower class microSD card may prevent the camera from recording data.
Both units come equipped with a 16GB Canvas Select microSD card from Kingston.
However, if you wish to replace or upgrade your microSD card, you can use any brand of microSD card with speed class 10.
