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 first.
■ Source: Select a stream for the recording source.
■ To enable recording notification, please configure the associated Event Settings first, please refer to
page 87.
