8. The images are poor quality, how can I improve the image quality?
Make sure that your computer's display properties are set to at least 6-bit color. Using 16 or 256 colors on your computer will produce dithering
artifacts in the image, making the image look as if it is of poor quality.
You may also need to check your image settings to make sure the brightness, contrast, and other settings are set properly. For more, refer to"Image
Setup" on page 28.
9. Why are no images available through the Web browser?
ActiveX might be disabled. If you are viewing the images from Internet Explorer make sure ActiveX has been enabled in the Internet Options menu.
You may also need to change the security settings on your browser to allow the ActiveX plug-in to be installed.
If you are using Internet Explorer with a version number lower than 6, then you will need to upgrade your Web browser software in order to view
the streaming video transmitted by the Network Camera.
