streaming audio and port 5003 for streaming video. these ports or the ports you specify
from the Advanced Tab in the Configuration screen, needs to be opened.

Ensure that the ports configured for the DCS-7510 on the router or firewall are correct. In
order to do that, you need to determine if the DCS-7510 is behind a router or firewall and
then properly configure the ports of your DCS-7510. 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, with an Ethernet crossover cable.

This might be caused by the firewall protection on your network. You may have to change
the firewall settings in order for the Network Camera to be accessible outside your local
LAN. Check with the Network Administrator and ensure 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.
