B. Overwrite HDD Data
• When the image becomes unnecessary, temporary data overwrite function will write
meaningless data over all area where images are stored, and destroy the image data
itself.

or HDD encryption function along with this function will provide a high level of security
which prevents images of great importance from leaking. It is recommended to use HDD
lock password function or HDD encryption function along with this function for those who
require high level of security.
