additional delay. However, there may be situations where the dynamic load balancing can lose too
many packets or switch to a mis-configured route, causing breaks in the video. You may be able to
avoid Dynamic Load Balancing by requesting a static route or MPLS (Multi-Protocol Labeled
Switching) service from your ISP.
1.5 Passwords and Security
The QVDEC4K
™ requires a username and password to protect access to its configuration
settings. This includes both Web access and SSH access. The default user name for the web
interface
is “
admin
” and the
default password is
set to its
serial number
. Logging in as the user
root
is not allowed.
Note on Resetting Password:
If you lose the password and need to reset it, you can go to
, click on
Reset Password
,
copy the “autorun” file onto a USB flash,
and plug flash into QVDEC4K
. (File must be saved as “autorun” and not “autorun.txt”.). This will
reset the admin password back to the serial number of the unit You must have physical access to
the USB ports on the QVDEC4K to use this procedure.
As shipped from the factory, the QVDEC4K comes with SSH and root access disabled. The RPM
update system used, as discussed in the next section on Updating, prevents any unauthorized
firmware from entering the unit. Should the user require shell or SSH access to the unit, a public-
private certificate-based system can be enabled that disallows shell login via username/password
as a further security enhancement.
1.6 Updating
QVidium provides firmware updates from time to time to add new features, overcome limitations, or
to fix bugs. The QVDEC4K firmware builds upon the Ubuntu/Linux RPM Package Manager to
catalog, manage, automate, secure, and simplify the update process. With a click to
System/Update
from the web interface, the QVDEC4K will connect to the QVidium update server
via the Internet to take inventory of which packages need to be updated and seamlessly keep the
QVDEC4K running with the latest features and more robust firmware available. This secure
mechanism forms a part of the overall protections that help to prevent malware and all non-
authorized firmware from infecting the QVDEC4K.
To update to the latest firmware, make certain that your unit has access to the Internet and click on
System/Update, then confirm that you wish to proceed. The system will connect to the QVidium
server, take inventory of the packages loaded on your QVDEC4K, and then proceed to determine
which packages need to be updated and download and install only those packages that need to be
updated. After this completes, you may need to reboot your system for the update to take effect by
clicking on
System/Reboot
from the web browser interface. You should also clear your web
browser’s cache or at least refresh the web pages after updating the firmware in case the new
firmware had changed some of the web pages.
