Frequently Asked Questions
Internet Camera Features
Q: What is an Internet Camera?
A:
The Internet Camera is a standalone system connecting directly to an
Ethernet or Fast Ethernet network.
It differs from a conventional PC Camera,
the Internet Camera is an all-in-one system with built-in CPU and Web-based
solutions providing a low cost solution that can transmit high quality video images
for monitoring. The Internet Camera can be managed remotely, accessed and
controlled from any PC/Notebook over an Intranet or the Internet from a Web
browser.
Q
:
What is the maximum number of users that can be allowed to access
DCS-2100+ simultaneously?
A:
The maximum number of users that can log onto the Internet Camera at the
same time is 10. Please keep in mind the overall performance of the transmission
speed will slow down when many users are logged on.
Q
:
What algorithm is used to compress the digital image?
A:
The Internet Camera utilizes H.263+ MPEG-4 Short Header Mode image
compression technology providing high quality images. MPEG is a standard for
image compression and can be applied to various Web browser and application
software without the need to install extra software.
Q:
Can I capture still images from the Internet Camera?
A:
Yes you are able to capture still images with the snapshot function from the
software application CD supplied with the Internet Camera.
Internet Camera Installation

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:
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 19 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.

Q:
Why does a series of broad vertical white lines appear throughout
the image?
A:
It could be that the CMOS sensor has become overloaded when it has been
exposed to bright lights such as direct exposure to sunlight or halogen lights.
Reposition the Internet Camera into a more shaded area immediately as
prolonged exposure to bright lights will damage the CMOS sensor.
Q: The focus on the Internet Camera is bad, how can I correct it?
A1:
Adjust the Internet Camera focus manually as described in
Adjusting the
Internet Camera Focus
in the Appendix section of this manual.
A2:
If you have previously changed the supplied CS-type lens, you may have
unintentionally installed a C-type lens without fitting the adaptor first.
Q:
Noisy images occur. How can I solve the problem?
A1:
The video images might be noisy if the Internet Camera is used in a very
low light environment. To solve this issue you need more lighting.
Frequently Asked Questions (continued)
Q: I connected the Internet Camera directly to a computer with a cross-
over cable Ethernet cable and received the following Windows error upon
running IP Installer:
A1:
This Windows error will occur if the Internet Camera is connected to a
computer that is not properly configured with a valid IP address.
Turn off DHCP
from the Network Settings in Windows and configure the computer with a valid
IP address or connect the camera to a router with DHCP enabled.
A2:
This error can also occur if the
IP Installer
icon is clicked on more than
once from the setup wizard.
