For example you can record 10 files on the SD Card. When the card is full, the loop mode erase the oldest video.
But if you are saving some protected videos, that videos cannot be deleted by the loop mode, but only on PC, or maybe formatting the card.
If you are saving 8 protected files, the camera record OK only 2 files in loop mode.
But if you are protecting 10 files, the camera will stop working because no space on the Card were to write the actual files.
Some cameras to not have this problem can save for example maximum 3 files, or based on size maybe 300MB.
I don't know how the cameras are protecting the files and I am thinking are three ways:
- renamed in some way which loop feature is not deleting them
- put them in another folder which is not affected by the loop feature
- mark them as read only when saving.
enjoy,
