DCS-2100 User’s Manual
D-Link Systems, Inc.
Using the DCS-2100 with an Internet Browser
Media Option:
Protocol Option:
Allows a user to disable audio when viewing video.
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-2100 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.
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
41). Only the HTTP port must be forwarded for remote users to
make an HTTP connection (video only).
