You can find the micro SD card slot on one side of the camera.
When inserting the micro SD card into the camera, make sure that the contact (metal) side of the card is facing towards the direction of USB interface.


Tips: please turn off the camera before inserting or removing the micro SD card from the camera.
The camera supports a micro SD card from 4 GB to 256 GB. (CAM1 supports 4GB TO 128GB, CAM3/ CAM5 supports 4GB to 256GB. The micro SD card is not included in the product box.)
Note 1: Make sure that the micro SD card has been formatted to FAT32 or exFAT on PC/MAC before inserting it into the camera.
Note 2: The camera saves videos on the micro SD card in MKV format. MKV is a modern video format that both MAC and Windows 10/11 can play without any extra software. Most media players also work with MKV.
If you can't open MKV files on your PC/MAC, you can install a popular media player like VLC or any another commonly used media player software.
