12. I connected the Internet Camera directly to a computer with a cross-over cable Ethernet cable and
received the following Windows error upon running the Installation Wizard:
This Windows error will occur if the Internet Camera is connected to a computer that is not
properly configured with a valid IP address. Turn off DHCP from the Network Settings in
Windows and configure the computer with a valid IP address, or connect the camera to a router
with DHCP enabled. (See page 140)
This error can also occur if the Installation Wizard icon is clicked on more than once from the
setup wizard.
13. Noisy images occur. How can I solve the problem?
The video images might be noisy if the Internet Camera is used in a very low light environment. To solve this issue
you need more lighting.
13. The images appear to be of poor quality, how can I improve the image quality?
Make sure that your computer's display properties are set above 256 colors. Using 16 or 256 colors on your
computer will produce dithering artifacts in the image, making the image appear to be of poor quality.
The configuration on the Internet Camera image display is incorrect. Through the Advanced > Image Setting
section of the Web management you need to adjust the image related parameters such as brightness, contrast,
hue and power line frequency for fluorescent light. Please refer to the Advanced > Image Setting section on Page
44 for detailed information.
