Switching TCP/UDP Transmission Mode

Switching TCP/UDP
Transmission Mode
You can select the communication port of the video/
audio data as TCP or UDP.
This function can be used when the Video mode
(page 34) is set to MPEG4 and the ActiveX viewer is
used.
1
Display the main viewer.
2
Click TCP/UDP transmission selector icon.
Transmission mode selector dialog appears.
3
Click one of the buttons TCP, UDP (Unicast) or
UDP (Multicast).
TCP: This is normally selected.
When TCP is selected as the communication port,
HTTP communication is adopted for video/audio
communication.
HTTP is the protocol used for reading a usual Web
page.
In an environment capable of reading Web page,
you can watch or listen to the video/audio by
selecting TCP port.
UDP (Unicast): When UDP (Unicast) is selected
as the communication port, RTP (Real-time
Transport Protocol) is adopted for video/audio
communication. As RTP is the protocol for running
video/audio data, video/audio can be played
smoother than when TCP (HTTP) is selected. If the
fire-wall is installed between the camera and the
computer, or depending on the network
environment, the video/audio may not play
properly when UDP (Unicast) is selected. In this
case, select TCP.
UDP (Multicast): This is selectable when the
multicast streaming (page 34) is On. When UDP
(Multicast) is selected as the transmission port,
RTP (Real-time Transport Protocol) and UDP
multicast techniques are adopted for video/audio
transmission. By selecting it, the network
transmission load of the camera can be reduced. If
a router which does not correspond to the multicast
or the fire-wall is installed between the camera and
the computer, the video/audio may not play
properly. In this case, select TCP or UDP
(Unicast).

If you decide not change the transmission setting,
click Cancel.
