12.2.11 Configuring System Recording Quality (Mainstream and Substream)

The system uses 2 recording streams: the Mainstream is the high-quality stream used for
live viewing and recording, while the Substream is a lower quality stream used for remote
viewing and playback. This allows you to record high-quality video locally, as well as re-
view video remotely with relatively low bandwidth requirements.
• For instructions on configuring the mainstream, see 12.2.11.1 Configuring the Main-
stream, page 60.
• For instructions on configuring the substream, see 12.2.11.2 Configuring the Sub-
stream, page 61.
