Please change another card reader to shoot machine trouble, if you still have questions please contact customer service for help. RMA@teamgroup.com.tw
Please identify that the video recording time is set to limit, instead of fixed time. If card format is FAT32, the recording would be stopped as 4GB of recording is reached because a single file cannot exceed 4GB. This problem may be solved as long as card format is changed to NTFS or exFAT if the two formats are supported by the machine.
