Switching Transmission Mode You can change the transmission mode for video/audio data. This function can be used when the ActiveX viewer in the live viewer is used.

In that case, disable the software or select the TCP mode. 1 Select TCP, Unicast or Multicast from the Connection drop-down list in the Other panel. Notes • When connecting via a proxy server, neither Unicast nor Multicast can be selected. • The settings of connection items are saved automatically. When saving as a setting other than TCP, ActiveX viewer may not operate properly depending on the network environment. In this case, return to the initial setting by deleting the file below.

Switching Transmission Mode
Switching Transmission
Mode
You can change the transmission mode for video/audio
data.
This function can be used when the ActiveX viewer in
the live viewer is used.
Selection of
Unicast
and
Multicast
is available only
when the video codec of image is set to
H.264
.
Note
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.
1
Select
TCP
,
Unicast
or
Multicast
from the
Connection
drop-down list in the
Other
panel.
TCP:
This is normally selected.
When
TCP
is selected, 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, 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
.
Multicast:
This protocol is selectable when
Multicast streaming
in the Streaming tab of the
Streaming menu is set to
Enable
. When
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
Unicast
.
Notes
•
When connecting via a proxy server, neither
Unicast
nor
Multicast
can be selected.
•
The settings of connection items are saved
automatically. When saving as a setting other than
TCP, ActiveX viewer may not operate properly
depending on the network environment.
In this case, return to the initial setting by deleting the
file below.
For example: the main drive is C
C:\Users\<User name>\AppData\Roaming\Sony\
SNCActiveXViewer\SNCActiveXViewer_configurati
