Section 5 - Troubleshooting

8. Can the DCS-3411/3430 be connected to the network if it consists of only private IP addresses?

Yes, the Network Camera can be connected to a LAN with private IP addresses.

9. Can the DCS-3411/3430 be installed and work if a ﬁrewall exists on the network?

If a rewall exists on the network, port 80 is open for ordinary data communication. The DCS-3411/3430 uses

port 5002 for streaming audio and port 5003 for streaming video. These ports (or the ports you specify from the

Advanced Tab in the Conguration screen if you change the default ports) need to be opened on the rewall.

10. Why am I unable to access the DCS-3411/3430 from a Web browser?

If a router or rewall is used on the network, the correct ports for the DCS-3411/3430 may not be congured on

the router or rewall. To correct the problem, you need to determine if the DCS-3411/3430 is behind a router or

rewall and if the router or rewall is properly congured for the ports the DCS-3411/3430 is using. Other possible

problems might be due to the network cable. Try replacing your network cable. Test the network interface of the

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

the Network Camera might be faulty.

11. Why does the Network Camera work locally but not externally?

This might be caused by network rewall protection. The rewall may need to have some settings changed in order

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

network.

Make sure that the Network Camera isn’t conicting with any Web server you may have running on your network.

The default router setting might be a possible reason. Check that the conguration of the router settings allow the

Network Camera to be accessed outside your local LAN.

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

received the following Windows error upon running the Installation Wizard:

This Windows error will occur if the Network Camera is connected to a computer that is not properly congured with

a valid IP address. Turn o DHCP from the Network Settings in Windows and congure 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.
