Chapter V. Troubleshooting and Maintenance

This section discusses basic problems with the USB Web Camera, frequently asked questions and provides some
maintenance tips.
Ensure the USB cable is correctly and securely attached.
Ensure that your video software has been properly installed.
Make sure your lens is free from obstructions, and that it is pointing in the appropriate direction.
Check that there is sufficient light for the camera. Alternatively, you may wish to adjust the Brightness or Contrast
settings in the software you are using.
Ensure there is no strong light source behind the object or person being viewed by the PC Camera.
Ensure that the lens is clean.
Q. Can I use my USB Web Camera with software applications other than those included with the camera?
Yes. A V ideo for Windows device driver and a TWAIN driver are supplied with your camera and are
A.
automatically installed on your computer during the setup process. These drivers allow the USB Web Camera to
be used as a general video and/or still image input device with other Windows applications.
Q. How do I use my USB Web Camera with other video capture devices?
A. The best way is to disable all other video capture devices and ensure the USB Web Camera is the default device.
To do this:
Click on the Start menu button and choose Settings, and then Control Panel. In the Windows Control
Panel, double click on the "Multimedia" icon.
Select the Devices tab at the top to view a list of all multimedia devices installed on your computer.
Double click on the driver name. This will open a dialog box showing your camera's properties.
Enable or disable the driver as required.
Note: Some applications (e.g. CU-SeeMe) allow you to select a device from within the application. If this is the
case, disabling other devices in the Windows Control Panel is not necessary.
Q. The video on my screen appears too light or too dark. What should I do?
A. Proper room lighting is critical for the correct functioning of the USB Web Camera. Your camera requires a
certain light level to produce good pictures. If you are getting dull or dark images, or if the color is poor, try
increasing the ambient light in the room, or lighting the subject directly. Using the camera in a sunlit room will
also produce good results. If you cannot use your camera in a naturally well-lit setting, then a desk lamp or
some other artificial light source must be used.
You may also wish to adjust the Brightness or Contrast settings usually located in a Video Source
(or similarly named) settings window in the software you are using.
