Vivotek H.264 manual Continuous recording

VIVOTEK

Recording name: Enter a name for the recording setting.

Enable this recording: Select this option to enable video recording.

With adaptive recording:

Select this option will activate the frame rate control according to alarm trigger. The frame rate control means that when there is alarm trigger, the frame rate will raise up to the value you’ve set on Video quality setting page. Please refer to page 54 for more information.

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