The number of selectable alarm output terminals is as
follows:
SNT-EX101/SNT-EX101E: 2
SNT-EX104/SNT-EX154: 4
SNT-EP104/SNT-EP154: None
Playing an audio file stored in the

You can play an audio file previously stored in the
system using the SNC audio upload tool.
To use this function, you need to make
Voice alert1
,
Voice alert2
and
Voice alert3
active in the Trigger menu
of the Administrator menu (page 79).
1
Click
Voice alert1
,
Voice alert2
or
Voice alert3
on
the Trigger panel.
Playback of the selected audio file starts and the
playback sound is output from the speaker
connected to the system.
Notes
• This operation is not available on the SNT-EP104 or
SNT-EP154.
• Voice alert configuration is only available for CH1 on
the SNT-EX154.
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.

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 system 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
.
