Section 3 - Configuration
7. Why does the 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
Day & Night Network Camera With WDR Sensor to be accessible outside of your local LAN. Check with the Network Administrator for
your network.
• Make sure that your Fixed Dome Day & Night Network Camera With WDR Sensor 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 Day
& Night Network Camera With WDR Sensor to be accessed outside of your local LAN.
8. I connected the 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 Day & Night Network Camera With WDR Sensor 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 had been clicked 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 Day & Night Network Camera With WDR Sensor 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 Day & Night Network Camera With WDR Sensor 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.
