LHB Series: Manual firmware upgrade

Your LHB Series DVR can receive firmware updates in three ways:

  • Automatically over a network, connected by an Ethernet cable (included). Click here for information on how to automatically upgrade firmware.
  • Manually by connecting a USB flash drive (not included) to your DVR.
  • Manually by connecting a USB flash drive (not included) to your PC / Mac and using the FLIR Client 12 software. Click here for information on how to manually upgrade firmware using FLIR Client 12 software.

IMPORTANT: It is recommended to use automatic upgrade unless directed by technical support to perform a manual upgrade. Technical support will provide you with a .bin file for manual firmware upgrade. Do not power off the DVR during a firmware upgrade.


  • Ensure your DVR system is connected to a network using the included Ethernet cable.
  • Save the .bin file in the root folder of a USB flash drive (not included)‎,‎ and connect the USB flash drive to a USB port on your DVR.

To manually upgrade the DVR firmware:

  1. In the taskbar, click the Main Menu icon (home icon), and then click Advanced > Maintenance.
