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 video streams in the full frame rate; otherwise, it will only
request the I frame data during normal monitoring, thus effectively save lots of bandwidth and storage.

■ Pre-event recording and post-event recording
The Network Camera has a buffer area; it temporarily holds data for up to a certain limit. Enter a
number to decide the duration of recording that will take place before and after a trigger is activated.

storage (SD card).
NOTE:
► To enable adaptive recording, please make sure
you've set up the trigger source such as Motion
Detection, DI Device, or Manual Trigger.

► When the I frame period is >1s on Video settings
page, it should be forced to make the I frame period
to 1s when adaptive recording is activated.
