Note
Some series products support three streams: main stream, sub stream 1, sub stream 2. The sub stream
maximally supports 1080P.
From Main menu->Setting->System->Encode, you can see the following interface. See Figure 4-49.
Channel: Select the channel you want.
Type: It is to set device bit stream type.
For main stream, there are three options: regular/motion detect/alarm. The sub stream supports
regular bit streams only.
The active control frame function (ACF) can record in different frame rates. For example, you can
use high frame rate to record important events, record scheduled event in lower frame rate.
Set different frame rates for different record events.
Note
Some series products do not support motion detect bit streams and alarm streams.
