“Secondary FTP passive mode” Passive mode setting for the backup FTP server.

In both methods, a "2nd" server can be provided for backup connection for “1st”. However the primary

server information should be entered first. If the primary server is not set, the related FTP or email will be

deactivated. Note that it may take time to connect to the secondary server after the first one fails and it

may affect some applications when conditions happen too often. For SMTP, video server will

automatically try to connect to 2nd SMTP server while failing to send out to 1st SMTP caused by any

wrong SMTP information.

For security or network integration, Administrator also can hide the server from the general HTTP port by

changing "HTTP port" to other than default 80. “Local FTP server port” can also be changed to other

than default 21. These ports of “Control Channel Port”, “Audio Channel Port” and “Video Channel

Port” which are used in media transmission can also be changed. Administrator should have enough

acknowledge before changing the default port.

NOTICE: if video server is behind NAT, port mapping is necessary for connection outside NAT.

HTTP port, control channel port, video channel and audio channel port totally 4 ports mapping

needs to set in the NAT router to enable fully video and audio streaming by video server.

If the Video Server works in variation or low bandwidth (comparing with video bandwidth) environment,

the client side will receive the poor quality of media. For improving this situation, you can check the

“Improve audio quality in low bandwidth environment” item. It can make the audio quality better, but

the media delay is longer and real-time issue is bad. If the network performance is worst, please select

the”UDP protocol“as the communication protocol in “client setting”

The Video server can disable audio streaming by check “Mute” check box. Any client connect to the

Video Server will receive video only. Once “Mute” is checked, the LED2 for heart beating status will

blink about every 2 seconds. It would be obviously slower than the normal condition with both video and

audio streaming. This way user can tell video server’s streaming behavior just from LED2

After everything is set, click on

. A warning message will pop up. Click on to confirm. The

Video Server will automatically restart. If "Reset network at next boot" is kept checked, run the installer

procedure again. Otherwise the Video Server will restart automatically.
