Frequently Asked Questions (continued)
Q: Can the Internet Camera be setup as a PC-cam on a computer?
A: No, the DCS-2100+ Internet Camera is used only on an wireless 802.11b,
Ethernet or Fast Ethernet network. The D-Link DSB-C110, DSB-C310 can be
used as a PC Camera (Webcam).
Q: Can the DCS-2100+ 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 DCS-2100+ 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-2100+ uses port 5001 for control and synchronization,
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 DCS-2100+ from a Web browser?
A1: If a router or firewall is used on the network, the correct ports for the
DCS-2100+ may not be configured on the router or firewall. To correct the
problem, you need to determine if the DCS-2100+ is behind a router or firewall
and if the router or firewall is properly configured for the ports the DCS-2100+
is using. Refer to Page 23 for help in opening the correct ports on a router or
firewall for use with the DCS-2100+.
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 Internet Camera might be faulty.
Q: Why does the 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 Internet Camera to be accessible
outside your local LAN. Check with the Network Administrator for your network.
A2: Make sure that the 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 Internet Camera to be accessed
outside your local LAN.
