Section 5 - Troubleshooting
7. Can the Network Camera be setup as a PC-cam on a computer?
No, the DCS-6410 Network Camera is used only on a Ethernet or Fast Ethernet network.
8. Can the DCS-6410 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-6410 be installed and work if a firewall exists on the network?
If a firewall exists in the network, port 80 is open for ordinary data communication. The DCS-6410 uses port 554
for streaming audio and video. These ports, or the ports you specify from the Advanced Tab in the Configuration
screen need to be opened in the firewall.
10. Why am I unable to access the DCS-6410 from a Web browser?
If a router or firewall is used on the network, the correct ports for the DCS-6410 may not be configured on the
router or firewall. To correct the problem, you need to determine if the DCS-6410 is behind a router or firewall and
if the router or firewall is properly configured for the ports the DCS-6410 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 firewall protection. The firewall 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 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 allow the
Network Camera to be accessed outside your local LAN.
