For easy update experience, recorder must be connected to internet and do an over-the-air (OTA) update. Sample video is for NVRx-8580. Same procedure is applicable to any units listed above or with similar interface.
If you can't do OTA, proceed below.

Download the firmware

• Once you have the needed firmware for your unit, save it to your flash drive (do not put it in a folder; extract if it is on a ZIP folder).
• We recommend a flash drive capacity of 32GB or smaller.
• The file extension (type of file) should be or have .sw at the end.

Update

1. Insert the flash drive into your recorder.
2. Access Menu and go to Advanced (left) then Maintain (top).
3. Click on Update.

4. A new window will open which shows the files in your flash drive. Select the firmware you downloaded then click on OK.

   NOTE: Filename varies per model. Use the firmware sent to you if there's any.

5. A confirmation window will appear, click on OK to continue.
6. The update will begin; do not interrupt it until the recorder has completed the update.
