Special Sd Card Settings - Vidicode V-Tap Manual

6.1 Special SD card settings

Next follows a description of some settings for the SD card, which must
be entered in Special Settings &
SD = Show free space on the card after each reboot
Enter "SD" as the first command in "Special Settings & Commands".
After each reboot and login, free space on the card is shown then.
(A reboot is also done after pressing the 'Save & Logout' button.)
.SR = Remove files from the card after sending
Normally, the files are kept on SD card and are not deleted by the
system, except when the maximum number of files is reached, in
which case the oldest files are overwritten automatically.
It is an option to delete the files after the content was sent to a
Tunnel server. A certain risk is taken then, because data cannot be
recovered anymore after deletion.
.SA = Disable Auto Delete when the card is almost full
When the card is almost full, the oldest files are deleted
automatically by the system to create space. This process can be
disabled, but new recordings will get lost in that case.
When disabled, the user must replace the card on time.
.FC<cou> = File Auto Close Packet Count (default 20)
.FT<sec> = File Auto Close Timeout in seconds (default 3)
These two parameters are used by the system to close files on the SD
card automatically. As soon as you insert an SD card, a file is opened,
and recorded data is written into the file. Stored packets are counted
each second again and when the installed threshold is reached, the
timeout becomes active. When the Packet Count is under the
threshold for the duration of the installed timeout, the current open
file is closed. A new file is opened immediately after that.
One normal VoIP call produces about 100 packets per second for the
duration of the call. After the call, a few or no packets are received.
In this way, the Auto Close function can be seen as an active-idle
detector. In the case that only one VoIP phone is connected, the files
on SD card will then contain complete calls. With more phones/calls
active at the same time, the files can also contain multiple calls.
