Operating the Camera 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, or Windows Vista, disable "Windows Firewall." For details, see "Configuring Windows Firewall" in "When using Windows XP Service Pack 2 or later" on page 9, or "Configuring Windows Firewall" in "When using Windows Vista" on page 11. 1 Select TCP, UDP (Unicast) or UDP (Multicast) from the Connection drop-down list in the Others panel. UDP (Multicast): This protocol is selectable when Multicast streaming (page 43) 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 that does not correspond to a multicast or firewall is installed between the camera and the computer, video/audio may not play back properly. In this case, select TCP or UDP (Unicast). 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. UDP (Unicast): When UDP (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 UDP (Unicast) is selected. In this case, select TCP. 25 Switching TCP/UDP Transmission Mode

Operating the Camera
Switching TCP/UDP Transmission Mode

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,
or Windows Vista, disable “Windows Firewall.” For
details, see “Configuring Windows Firewall” in
“When using Windows XP Service Pack 2 or later” on
page 9, or “Configuring Windows Firewall” in “When
using Windows Vista” on page 11.

Select
TCP, UDP (Unicast)
or
UDP (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.
UDP (Unicast):
When
UDP (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
UDP (Unicast)
is selected. In this
case, select
TCP
.
UDP (Multicast):
This protocol is selectable when
Multicast streaming
(page 43) 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 that does not correspond to a multicast or
firewall is installed between the camera and the
computer, video/audio may not play back properly.
In this case, select
TCP
or
UDP (Unicast)
