i have purchased three of these and 3 64gb adata micro sd cards,
as of yet im having issues with getting the video to record to the card/playback.
so far i have reformatted to exFAT to fix the 32gb limit of fat32 via windows. re-partitioned the card after having the camera format/initialize the card and ended up with two partitions.

of interest i notice any files written to the card are all the same creation date and time but different file name.

so far when i login to the web interface to play back the recorded footage im prompted with no file found, i have also updated to the latest firmware 5.4.0 in the hopes that would fix any issues.

Bit stuck as i think i have covered all my bases
Any help would be much appreciated.
