Importing a Root Certificate for FTPS
If the FTP mode is set to [ FTPS ] when configuring the connection settings, the root
certificate corresponding to the FTPS server to connect to must be imported to the camera.
Only a root certificate whose file name is " ROOT.CER ", " ROOT.CRT ", or " ROOT.PEM "
can be imported to the camera.
Only one root certificate file can be imported to the camera. Insert a card containing the
root certificate file in advance.
The priority card selected for [
Record/play ] or [ Play ] is used to import a
certificate when [ / separate ] in [ : Record func+card/folder sel. ] is set to
[ Disable ]. Card 2 is used when [ / separate ] is set to [ Enable ].
The connected server may not be trustworthy if an FTPS connection is established by
using a self-signed certificate.
