Firmware is a type of computing software that is used in the management and operation of nearly all electronics. The VMAX® Series DVRs utilize firmware versions to manage camera communication, user interface controls, display, and recording settings for every interaction by the user.
Periodically, the firmware version may need to be upgraded to apply new features, improvements, and other content to the DVR.
This article will explain the process for upgrading Firmware for the VMAX® Series DVRs using either File Transfer Protocol (FTP) or a USB stick.
**NOTE: The term “Legacy” refers to a product/device that has been discontinued due to stop of production, supersession by a newer product, etc. For a list of Legacy DW products that have been discontinued, you may visit:
**NOTE: When upgrading the firmware of a DVR using a USB stick, it is important to ensure that the firmware file is not stored in a folder. If a firmware file is stored in a folder or as a compressed file (.zip), the DVR will not be able to read the firmware file. Please make sure that the firmware file is placed in the root directory of the USB stick.
Firmware upgrades for the VMAX® Series will need to be performed directly at the DVR. Connect a display monitor and USB mouse to the DVR, so that you can control the user interface of the recording unit.
If you are unsure what type of display (HDMI or VGA) that your DVR supports, please consult the User Manual.
The FTP upgrade option permits users to upgrade DVR firmware by communicating with an external FTP server over the Internet. New firmware versions can be downloaded and installed by communicating with the FTP server.
The FTP function requires a stable network and Internet connection. If you have not set up the DVR Network settings, please read Network Setup For A VMAX DVR.
If the DVR has been placed behind a Firewall or Sonicwall, port forwarding may be required. Digital Watchdog does not offer port forwarding assistance. Please contact your Network Administrator or the ISP (Internet Service Provider) if port forwarding assistance is needed.

The USB upgrade option permits users to upgrade DVR firmware by inserting a USB stick and uploading the firmware file directly to the System.
**NOTE: The USB stick must use FAT or FAT32 format and should not exceed 32 GB. It is recommended to avoid the use of Kingston and San Disk brand USB sticks, as the DVR may experience an issue while allocating the firmware file from the USB.
If you do not have a copy of the latest firmware file:
This model information is located on the sticker, physically on top of the DVR.
The firmware file must be placed in the root directory of the USB stick as the file cannot be read by the DVR if it is stored in a folder. If the firmware file is stored as a compressed file (.zip), please make sure to extract the firmware file and save it in the root directory of the USB stick.
