Switching TCP/UDP
Transmission Mode
You can select TCP or UDP as the communication port
for video/audio data.
This function can be used when Mode (video codec
mode) is set to
MPEG4
or
H.264
and the ActiveX
viewer is used.
Notes
• The function may not operate correctly if you use
personal firewall software or antivirus software on
your computer. In that case, disable the software or
select the TCP mode.
• If you are using Windows XP Service Pack 2 or later,
Windows Vista, or Windows 7, disable “Windows
Firewall”. For details, see “Configuring Windows
Firewall” in “When using Windows XP Service Pack
2 or later” on page 9, “Configuring Windows
Firewall” in “When using Windows Vista” on page 11,
or “Configuring Windows Firewall” in “When using
Windows 7” on page 14.
1
Select
TCP, Unicast
or
Multicast
from the
Connection
drop-down list in the Others panel.
TCP:
This is normally selected.
When
TCP
is selected as the communication port,
HTTP communication is adopted for video/audio
communications. HTTP is the protocol used for
reading the usual Web page. In an environment
capable of reading Web pages, you can watch or
listen to video/audio by selecting the TCP port.
Unicast:
When
Unicast
is selected as the
communication port, RTP (Real-time Transport
Protocol) is adopted for video/audio
communications. Since RTP is the protocol for
running video/audio data, the video/audio playback
is smoother than when TCP (HTTP) is selected. If
a firewall is installed between the camera and the
computer, or depending on the network
environment, video/audio may not play back
properly when
Unicast
is selected. In this case,
select
TCP
.
