2.11 On Demand Display
For cameras that support dual streaming with different resolutions, you can select the On Demand
Display option to enable automatic adjustment of live view resolution. This option produces good
image quality without causing high CPU usage.
You will need to set one video streaming of the camera to be higher than the other streaming. The
system will switch to the higher resolution streaming when using view modes that require higher
quality images, such as single view or PIP/PAP mode. When watching live view in view modes where
higher resolution does not make a difference, such as a 16-channel screen division, the system will
switch to the lower resolution streaming to reduce CPU usage.
To enable the function:
1. Make sure the IP camera has been added to the Main System and you have selected Dual
Stream during setup. For details on how to add an IP camera, see IP Channel Setup earlier in
this chapter.
2. Click the Configure button, select System Configure, select Camera Install and select IP
Camera Install. The IP Device Setup dialog box appears.
3. Right-click the camera and select On Demand Display.

4. Point to Enable, When View Size Bigger Than, and select a resolution. When the resolution
of the camera image on the screen is bigger than or equal to the selected resolution, the
system will switch to the higher resolution streaming.
