If you enable adaptive recording 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.
■ 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.
■ Channel # Stream #: Select a channel and a stream under it as the recording source.
► To enable adaptive recording,
