Digital Signature

The Digital Signature function enables the user to export a video clip with the
unit's unique signature key. It aims to authenticate a video clip exported from
the unit and prove it has not been modified. The user can export a video clip
with or without a digital signature file (*.sig). Set the item to <YES> to export
with the signature file, or <NO> to export without the signature file.
Make sure that you have an external storage device, such as a USB Hard
Drive or USB ThumbDrive
for export.
