Recording options
On the camera Recording page, you can configure the following:
1. Configure the duration of camera events, for the concern that camera can be too
frequently triggered.
2. Enter the Pre- and Post-event recording time. The triggering events can be DI,
DO, Motion detection, PIR, or Tampering detection.
3. The default recording stream is Stream 1, and the system automatically adjusts
the frame rate, resolution, etc. for optimum performance. However, you can still
change the streaming characteristics. Note that you can not assign the recording
task to other video stream.
4. Enable the Activity Adaptive Streaming feature. This feature records the I-frames
only when there are no activities detected. While when activities or alarm is
triggered, the camera raises the recording stream to the full frame rate. This
feature can save tremendous ammount of bandwidth.
5. Enable or disable audio recording.
6. Change the life expectancy of the recording data.
7. You can apply a typical configuration to all cameras using the Apply to all cameras
checkbox.
You can refer to the User Manuals that come with your network cameras for more
discussions of these configurable options.
