Frequently Asked Questions (continued)
Q: The focus on the Internet Camera is bad, how can I correct it?
A1:
Adjust the Internet Camera focus manually as described in Adjusting the
Internet Camera Focus in the Appendix section of this manual (page 134).
Q: Noisy images occur. How can I solve the problem?
A: 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: 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:
A1: 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.
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 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 48 and 49 for detailed information.
