LHA / LNK Series: Configuring substream recording settings

Your LHA / LNK Series DVR / NVR system uses two different recording streams:

  • Mainstream: a high-quality stream used for live viewing and recording.
  • Substream: a lower quality stream used for remote viewing and playback.

You can use these recording streams to record high-quality video locally and review video remotely with low bandwidth.


  • NVR units also support a Mobilestream to set a custom video stream for remote viewing purposes. The following instructions require you to access your system using your DVR / NVR and a monitor.

To configure a Substream recording stream:

  1. In the taskbar, click the Main Menu icon (home icon), and then click Settings > Record > Substream.

  3. In the Resolution drop-down, select a recording resolution.

  4. In the FPS drop-down, select the number of frames per second.
