recording size on video noise conditions, and restore normal recording size when the disturbing
conditions are over.
1. Click the Configure button (No. 14, Figure 1-2), point to General Setting, and select System
Configure. In the System Configure dialog box, click the Camera Record Setting tab.
2. To set the recording mode to Round-the-Clock, enable Rec Video and select Round-the-clock
from the drop-down list.
3. Enable Apply Advanced Codec Setting and click the button. This dialog box appears.

4. Select Noise detection to reduce file size and adjust the Sensitivity level. The higher the value,
the more sensitive the system is to video noise.
5. Click Apply.
When the option is selected and video noise conditions are detected, you can see the icon
overlaid on the right-bottom corner of recorded videos. So you can easily distinguish the normal- size
segment from reduced-size segment. Note the icon does not appear on live video.
Note: You can also use this function when the recording mode is set to Motion Detection.
