Why does a series of broad vertical white lines appear through out the image?
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.
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.
The are poor quallity, how can I improve the image quality?
Make sure that your computers 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.
The configuration on the Internet Camera image display is incorrect. Through the Web Configuration Video section
of the web management 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.
Why are no Images available through the Web browser?
The 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 of lower than 5, then you will need to upgrade your Web browser
software in order to view the streaming video transmitted by the Internet Camera.
