Troubleshooting (continued) Internet Camera Installation Q: Why does a series of broad vertical white lines appear through out the image? A: It could be that the CMOS sensor (a square panel situated behind the lens that measures the light signals and changes it into a digital format so your computer can present it into an image that you are familiar with) has become overloaded when it has been exposed to bright lights such as direct exposure to sunlight or halogen lights. Reposition the Internet Camera into a more shaded area immediately as prolonged exposure to bright lights will damage the CMOS sensor. Q: Noisy images occur. How can I solve the problem? A1: 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. Q: The images are poor quality, how can I improve the image quality? A1: Make sure that your computer's display properties are set to at least 16-bit color. Using 16 or 256 colors on your computer will produce dithering artifacts in the image, making the image look as if it has bad quality. A2: The configuration on the Internet Camera image display is incorrect. Through the Web Configuration Video section of the web management (see P. 33) you need to adjust the image related parameters for improved images such as: brightness, contrast, hue and light frequency. Please refer to the Web Configuration section for detailed information. 83

A:
It could be that the CMOS sensor (a square panel situated behind the lens that
measures the light signals and changes it into a digital format so your computer can
present it into an image that you are familiar with) has become overloaded when it has
been exposed to bright lights such as direct exposure to sunlight or halogen lights.
Reposition the Internet Camera into a more shaded area immediately as prolonged
exposure to bright lights will damage the CMOS sensor.
Q:

A1:
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.
Q:

Make sure that your computer’s display properties are set to at least 16-bit color.
Using 16 or 256 colors on your computer will produce dithering artifacts in the image,
making the image look as if it has bad quality.

Web Configuration Video section of the web management (see P. 33) you need to adjust
the image related parameters for improved images such as: brightness, contrast, hue
and light frequency. Please refer to the Web Configuration section for detailed information.
