Figure 7-9 Recording Settings Details
• 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 control means that when there is a triggered alarm, the frame rate will raise up
to the value you’ve configured on the Video quality page. For more information, see Smart
Stream III on page 34.
If you enable adaptive recording on a camera, only when an event is triggered on camera
will the server record the full frame rate streaming data; otherwise, it will only request the I
frame data during normal monitoring, thus effectively saves bandwidths and storage
space.
Note
• To enable adaptive recording, make sure you’ve set up the
trigger source such as Motion Detection or Manual Trigger. For
more information, see Configuring Event Settings on page 60.
• When there is no alarm trigger:
• JPEG mode: record 1 frame per second.
• H.264 mode: record the I frame only.
• When the I frame period is >1s on Video settings page, firmware
will force decreasing the I frame period to 1s when adaptive
recording is enabled.
• Pre-event recording and post-event recording
The camera has a buffer that temporarily holds data for a period. Therefore, when an event
occurs, the camera can retrieve image frames taken several seconds ago. Enter a number
to define the duration of recording before and after a trigger is activated.
