I believe the card used to work, although I switched cameras around a bit and honestly I am not 100% sure I had used the recording on this one.
I reformated several times, but that did not help (both using windows reformat, and through amcrest surveillance pro). When going into Storage/HDD is shows 0g/0g, so it is seeing the card (when the card is not in, it shows nothing).
I ordered a pack of these SD cards, and the others are working fine.
I moved the card to a different camera, and had the same issue. So it is an SD card issue, not a camera issue.
