the video frame rate to full on the occurrence of an event. Doing so can save the bandwidth and storage

requirements.

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 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 77.

■ Pre-event recording and post-event recording

The Network Camera comes with a buffer area. The buffer temporarily holds data up to a certain limit.

This enables the camera to record pre- and post-event videos. Enter a number in each text box.

■ Priority: Select the relative importance of this recording (High, Normal, or Low). Recording with a
