Section 5 - Troubleshooting
Yes, the Internet Camera can be connected to a LAN with private IP addresses.
If a rewall exists on the network, port 80 needs to be opened for ordinary data communication. The DCS-
5605/5635 uses HTTP port and RTSP port to stream video data. These ports (or the ports you specify from the
Advanced Tab in the Conguration screen if you change the default ports) need to be opened in the rewall device.
Please refer to page 77 for more information.
If a router or rewall is used on the network, the correct ports for the DCS-5605/5635 may not be congured on the
router or rewall. To correct the problem, you need to determine if the DCS-5605/5635 is behind a router or rewall
and if the router or rewall is properly congured for the ports the DCS-5605/5635 is using. Refer to page 77 for
help in opening the correct ports on a router or rewall for use with the DCS-5605/5635.
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 Internet Camera might be faulty.
This might be caused by network rewall protection. The rewall may need to have some settings changed in
order for the Internet Camera to be accessible outside your local LAN. Check with the Network Administrator for
your network.
Make sure that the Internet Camera is not conicting with any Web server you may have running on your network.
The default router setting might be a possible reason. Check that the conguration of the router settings allow the
Internet Camera to be accessed outside your local LAN. Please refer to page 77 for more information.
