DCS-660 User's Manual Frequently Asked Questions
Q: Can the PTZ Internet Camera be setup as a PC-cam on a computer?
A: No, the PTZ Internet Camera is used only on an Ethernet or Fast Ethernet network. The D-Link DSB-
C110, DSB-C310, can be used as a PC Camera (Webcam).
Q: Can the PTZ Internet Camera be connected to the network if it consists of only private IP
addresses?
A: The PTZ Internet Camera can be connected to a LAN with private IP addresses.
Q: Can the PTZ Internet Camera be installed and work if a firewall exists on the network?
A: If a firewall exists on the network, port 80 is open for ordinary data communication. The DCS-6620
uses port 500 for streaming audio and port 5003 for streaming video. These ports (or the ports you
specify from the Advanced Tab in the Configuration screen if you change the default ports) need to be
opened on the firewall. Please refer to page 8 for more information.
Q: Why am I unable to access the PTZ Internet Camera from a web browser?
A1: If a router or firewall is used on the network, the correct ports for the DCS-6620 may not be configured
on the router or firewall. To correct the problem, you need to determine if the DCS-6620 is behind a router
or firewall and if the router or firewall is properly configured for the ports the DCS-6620 is using. Refer
to Page 8 for help in opening the correct ports on a router or firewall for use with the DCS-6620.
A2: 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 PTZ Internet Camera might be faulty.
Q: Why does the PTZ Internet Camera work locally but not externally?
A1: This might be caused by network firewall protection. The firewall may need to have some settings
changed in order for the PTZ Internet Camera to be accessible outside your local LAN. Check with the
Network Administrator for your network.
A2: Make sure that the PTZ Internet Camera isn't conflicting with any Web server you may have running
on your network.
A3: The default router setting might be a possible reason. Check that the configuration of the router
settings allow the PTZ Internet Camera to be accessed outside your local LAN. Please refer to page 31
for more information.
