Frequently Asked Questions (continued)
Q: Can the Internet Camera be setup as a PC-cam on a computer?
A: No, the 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 Internet Camera be connected on the network if it consists of
only private IP addresses?
A: Yes, the Internet Camera can be connected to a LAN with private IP
addresses.
Q: Can the 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-3220 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 Configuration screen if you change the default ports)
need to be opened on the firewall.
Q: Why am I unable to access the Internet Camera from a Web browser?
A1: The possible cause might be the IP Address for the Internet Camera is
already being used by another device. To correct the possible problem, you
need to first disconnect the Internet Camera from the network. Then run the
PING utility (follow the instructions in the Appendix - How to Ping Your IP
Address.)
In Windows 95/98/2000, check that the IP Address of the Internet Camera is
within the same subnet as your workstation.
Click Start, Setting, Control Panel, and the Network icon.
Select TCP/IP from the Network dialog box and from the TCP/IP Properties
dialog box click on Specify an IP address.
If the Internet Camera is situated on a different subnet than your workstation,
you will not be able to set the IP address from this workstation. To verify
make sure the first 3 sections of the IP address of the Internet Camera
corresponds to the first 3 sections of the workstation. Therefore the IP
address of the Internet Camera must be set from a workstation on the
same subnet.
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 standard Crossover Cable. If the problem is
not solved the Internet Camera might be faulty.
