the video file.

Recording strategy when the disk is full.
Stop: Stop recording when the disk is full.
Overwrite: Cyclically overwrite the earliest video when the disk is full.
Record

When you select Manual, the system starts recording; when you select Auto,
the system starts recording in the configured time period of record plan.

Select record stream, including Main Stream and Sub Stream.
Click Save. Step 3
