Omg you are genius!! That worked .. I didn't even know that was there and could not find any documentation.MicroSD card should fit in here (see pic).
If it is physically installed but does not show up in the menu, it's a software/firmware issue.
What firmware version are you running on the VTH?
thanks for your reply - i didnt get manuals and I have looked online but having a bit of trouble understanding which is why i reached out - not where in any manual did it say there was a slot in the back for the SD cardJust follow the manual(s).
