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.

The alarm trigger includes: motion detection and DI detection. Please refer to Event settings on page 98.

■ 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 rst.

■ Source: Select a stream for the recording source.

► To enable adaptive recording, please also enable time shift caching stream and select a caching

stream on Media > Video > Stream settings. Please refer to page 58 for detailed instruction.

► To enable recording notication please congure Event settings rst. Please refer to page 98.
