Important:
Some ISPs block access to port 80. Be sure to check with your ISP
so that you can open the appropriate ports accordingly. Some ISPs block traffic
on commonly used ports to conserve bandwidth. If your ISP does not pass
traffic on port 80, you will need to change the port the camera uses from 80 to
something else, such as 800. Not all routers are the same, so refer to your
user manual for specific instructions on how to open ports.

Viewing Your Camera
Viewing the DCS-2000 Remotely
After all settings have been entered correctly, a PC user inside or outside your
network will have access to the camera through the Internet Explorer Web
browser. To access the camera from the Internet, type the IP Address of the
router given to you by your ISP, followed by a colon, and the port number that
you gave your camera (e.g.,
). It is not necessary to
enter the colon and port number if you are using the default Web server port
80. To access from a computer on your local (home) network, simply enter the
local IP Address of the Camera followed by a colon and the port number (e.g.,
205.163.122.96:83
)
.

Open your Internet Explorer Web browser and enter the IP address for your
Internet Camera.
In the example, this address is 192.168.0.146.
Your address may differ.

If you are following this manual in the order it is presented, you should now have
an operating

Internet Camera configured with the Installer program.
You also have installed the
IP surveillance
software from the CD. This section
of the manual will deal with using the Internet Camera in two parts:
±
Using
the
DCS-2000
with an Internet browser and accessing
the screens to control and monitor the camera.

Protocol Option
The UDP Protocol should be
chosen for the most users.
Generally the client computer
will
automatically try these protocols
in the following order, UDP -> TCP
-> HTTP.
After the client connects to the
DCS-2000
successfully, the working protocol
will be displayed in “
Protocol Option
.” The chosen protocol will be recorded in
the user’s PC and used for the next connection. If the network environment is
changed or users want to let the Web browser automatically detect the protocol,
select UDP manually and click
Save
to change the setting and return
Home
to
reconnect with the new setting.
Media Option:
Option for users to disable or
enable audio when viewing video.
The following options are available
from
the Connections settings
screen:

Options:
UDP Protocol
- Offers the highest image and video quality.
However, packet losses will diminish image quality when bandwidth
becomes restricted.
TCP Protocol
- Packet loss is less likely to occur compared to UDP
when bandwidth is restricted.
HTTP Protocol
- If the network is protected by a firewall and it opens
HTTP port (80) only, HTTP protocol must be selected. In this mode,
audio is disabled and only video can be viewed. TCP and UDP
connections will not be available to remote users if all four ports have
not been forwarded (as shown on page 30). Only the HTTP port must
be forwarded for remote users to make an HTTP connection (video
only).
