Defaults If you like a particular setting for one application or light condition, and another setting for a different one, you can use the Restore and Save buttons to save and restore these preferred settings. Should you wish to restore all standard settings, click on the Restore button under Factory Defaults. 5.2.1.3 Capture Source The third tab is �Capture Source�. Usually this setting has only one option when the USB PC Camera is the only video source connected to your computer. However, if more than one video source is connected to your system, then this is where you switch between them.
