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.
