Activity Adaptive Stream

■ Activity Adaptive Stream: (Note that this feature may not be available for some older models)

This option will activate the frame rate control according to alarm trigger.

The frame control means that when there is a triggered alarm, the frame rate will raise up to the value

you’ve congured on the Video quality page.

If you enable adaptive recording on a camera, only when an event is triggered on a camera will the

server record the full frame rate streaming data; otherwise, it will only request the I frame data during

normal monitoring, thus e󰀨ectively saves bandwidth and storage space.

The alarm trigger includes: motion detection and DI detection. Please refer to Alarm Settings on page

127.

On individual cameras, you can congure the following:

■ Pre-event recording and post-event recording

The Network Camera has a bu󰀨er that temporarily holds data for a period of time. Therefore, when an

event occurs, the camera can restrieve image frames taken several seconds ago. Enter a number to

dene 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 video stream as the recording source.
