Vivotek PT8133 user manual Continuous recording

VIVOTEK

With adaptive recording:

Select this option will activate the frame rate control according to alarm trigger. The frame control means that when there is a triggered alarm/event, the frame rate will raise up to the value you’ve set on the Stream setting page. Please refer to page 74 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 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.
