interface of the product by connecting a local computer to the unit, utilizing a Ethernet crossover cable. If the problem is not solved,

the Fixed Dome Network Camera might be faulty.

7. Why does the Fixed Dome Network Camera work locally but not externally?

• This might be caused by network ﬁrewall protection. The setting of the ﬁrewall may need to be changed in order for the Fixed Dome

Network Camera to be accessible outside of your local LAN. Check with the Network Administrator for your network.

• Make sure that your Fixed Dome Network Camera isn’t conﬂicting with any Web server you may have running on your network.

• The default router setting might be a possible reason. Check that the conﬁguration of the router settings allows the Fixed Dome

Network Camera to be accessed outside of your local LAN.

8. I connected the Fixed Dome Network Camera directly to a computer with a cross-over Ethernet cable and

received a Windows error upon running the installation Wizard?

• This Windows error will occur if the Fixed Dome Network 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.

• This error can also occur if the Installation Wizard icon is clicked on more than once from the setup wizard.

9. Noisy images occur. How can I solve the problem?

The video images might be noisy if the Fixed Dome Network Camera is used in a very low light environment. To solve this issue you

need more lighting.

10. 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 Fixed Dome Network Camera image display is incorrect. Through the Setup>Image Setup section of the

Web management you need to adjust the image related parameters such as brightness, white balance and power line frequency for

ﬂuorescent light.
