Frequently Asked Questions
Q: Noisy images occur. How can I solve the problem?
A: The video images might be noisy if the 802.11g PTZ Internet Camera is used in a very low
light environment. To solve this issue you need more lighting.
Q: I connected the 802.11g PTZ Internet Camera directly to a computer with a cross-over cable Ethernet
cable and received the following Windows error upon running the Installation Wizard:
A1: This Windows error will occur if the 802.11g PTZ 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.
A2: This error can also occur if the Installation Wizard icon is clicked on more than once from
the setup wizard.
Q: The images appear to be of poor quality, how can I improve the image quality?
A1: 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.
A2: The configuration on the 802.11g PTZ 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 50 and 51 for detailed
information.
