■ Recording name: Enter a name for the recording setting.
■ Enable this recording: Select this option to enable video recording.
■ With adaptive recording:
Select this option will activate the frame rate control according to alarm trigger. The frame control
means that when there is a triggered alarm/event, the frame rate will raise up to the value you've set
on the Stream setting page. Please refer to page 59 for more information.
If you enable adaptive recording on Camera A, only when an event is triggered on Camera A will the
server record the streaming data in full frame rate; otherwise, it will only request the I frame data during
normal monitoring, thus effectively save lots of bandwidths and storage.
