Recording Settings
Click Add to open the recording setting page. On this page, you can define the adaptive recording,
recording source, recording schedule, and recording capacity. A total of 2 recording settings can be
configured.
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 alarm trigger, the frame rate will raise up to the value you've
set on Audio and Video page. Please refer to page 55 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 full frame rate streaming data; otherwise, it will only
request the I frame data during normal monitoring, thus effectively save lots of bandwidths and storage.

Continuous recording
When there is no alarm trigger:
- JEPE mode: record 1 frame per second.
- H.264 mode: record I frame only.
- MPEG-4 mode: record I frame only.
When the I frame period is >1s on Video settings
page, it should force to make the I frame period to
1s when adaptive recording is activated.
