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.
The alarm trigger includes: motion detection and DI detection. Please refer to Event settings on page 102.
■ 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.
■ 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 as the recording source.
► To enable recording notication, please congure Event settings rst. Please refer to page 102.
Please follow steps 1~2 below to set up the recording:
