LHA / LNK Series: Configuring mainstream recording settings
The 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.
Prerequisites:
