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 74 for more information.
.
If you enable adaptive recording and enable time-shift cache stream 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.
The alarm trigger includes: motion detection and manual trigger, etc. Please refer to Event settings on
page 87.
■ Pre-event recording and post-event recording
The Network Camera has a buffer area; it temporarily holds data up to a certain limit. Enter a number
to decide the duration of recording before and after a trigger is activated.
■ Priority: Select the relative importance of this recording (High, Normal, or Low). Recording with a higher
priority setting will be executed rst.
■ Source: Select a stream for the recording source.
■ To enable recording notication, please congure the associated Event Settings rst, please refer to
page 87.
