Using the DCS-2100+ with an Internet browser
(continued)
Home > Connection Type Screen
The following options are
available from the Connection
Type screen:
Media Option:
Allows a user to disable audio
when viewing video.
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-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 32). Only the HTTP port must be
forwarded for remote users to make an HTTP connection (video only).
