How To Update Uniview Series NVR Firmware

There are multiple paths available to apply updated firmware patches to Uniview products. Both the IP
camera and NVR product lines will have periodic updates produced in order to fix any bugs that may
have been found and also to potentially enable new features. When preparing to apply firmware
patches, it is vitally important that the equipment being updated be identified exactly and the
appropriate firmware be used. Applying firmware to an incorrectly identified unit could result in that
piece of equipment being rendered unresponsive.
Local firmware updates should only be attempted using versions that have been provided by Gen IV
Technical Support. Attempting a firmware update with unauthorized firmware will render your
warranty null and void and could be dangerous to your hardware and potentially contain malware.


Updating NVR Firmware


When applying firmware updates to a Uniview NVR, there are several methods available: locally using a
USB flash drive, locally using the Internet cloud update, remotely via the web interface using a local file,
remotely via the web interface using the Internet cloud update and remotely using the EZTools utility
and a local file.
When applying firmware updates, you should never interrupt the upgrade process. This could
potentially cause the unit being upgraded to be rendered unresponsive. It is also recommended that if
you are performing a remote update using a locally stored file that you only do so from a PC that is on
the same local area network. Attempting to update firmware over the Internet with locally stored files
is not recommended due to potential corruption caused by lag and network time-out issues.

Updating NVR locally Using a USB Flash Drive


In order to update an NVR using a USB flash drive, you will first need to download the appropriate
firmware. In most cases this firmware will be downloaded in the form of a zip archive. You will need to
prepare a USB flash drive by formatting it on a local PC using the FAT32 file system (the USB flash drive
should have at least 512MB of available free space). Once formatted, extract the contents of the zip
archive (usually a file named program.bin) onto the USB flash drive.
Insert the flash drive into your NVR and bring up the main menu by right-clicking the mouse or left-
clicking on the Home icon on the menu bar (if available). Using the mouse, left-click on Maintain and
then Upgrade. By default the NVR will show the contents of the USB flash drive on the Local Upgrade
tab and you may highlight the “Program.bin” file and then click on the Upgrade button at the bottom.
The upgrade process will show a progress bar and upon completion the NVR will reboot. Below is an
image showing the local upgrade screen.

Updating NVR Locally Using Internet Cloud Update



If your NVR is connected to a network with Internet access, you may utilize the Internet cloud update
feature to check online to see if a new version is available and to perform the update.
Bring up the main menu by right-clicking with the mouse or left-clicking on the Home icon on the menu
bar (if available). Using the mouse, left-click on Maintain and then Upgrade and then select the tab
entitled Upgrade by Cloud. You will be shown the current version of firmware installed on the NVR and
can click on the Check button at the bottom to see if a more recent version is available. If a new version
is available, you need only to click on the Upgrade button at the bottom and the download and upgrade
process will begin. After updating, the NVR will automatically reboot.

If the Internet cloud update fails, it may be the result of the current version of firmware that is installed
on the NVR not being on the compatibility list for updating and a manual update may be required at that
point until the cloud update servers can be configured with the proper versions.

Updating NVR Remotely Using Local File and Web Interface


If your NVR is accessible on the local area network using the web interface, you may update the
firmware using a file that has been downloaded and stored locally. Within the Settings section of the
web interface, go to the Maintenance section and select the Maintenance entry. On the screen that
comes up, click on the Browse button next to the Upgrade text entry field and browse to the location on
the local PC where the firmware file is stored and click on it. Once the file is properly entered, press the
Upgrade button and the unit will perform the upgrade procedure including a reboot which will
terminate your connection.

Updating NVR Remotely Using Local File and EZTools Utility


If your NVR is accessible via the local area network you may perform a firmware update using the
EZTools utility program with a file that has been downloaded and stored locally. Begin by opening the
EZTools program which will find devices that are on your local area network. Locate your NVR and click
on the Maintenance button. You will be prompted for the username and password to log into the
device, this user must be an administrative level account. After logging in the Maintenance window will
be shown and you will look for the first section titled Software Upgrade. Click on the Browse button and
navigate to the location of the firmware file, select it and click on Upgrade to being the process. The
NVR will reboot after the upgrade completes.
