VPort 2140 User’s Manual System Configuration
4-6
2. ; Reset network at next boot
In this case, the installation process must be run again when system reboots. This is the default
setting.
ATTENTION
You can ignore this option if you are using the Modem Dial-up connection.
General
Administrators may need to modify the network settings to connect to an existing network, since
the subnet mask in some broadband service may differ from the default value of 255.255.255.0,
and service providers may assign more specific network settings. Administrators should change
the configuration to the settings given by the service provider. The configuration may include IP
address, Subnet mask, Default router, Primary DNS server, and Secondary DNS server.
After changing network settings, make sure to uncheck the “Reset network at next boot option” to
avoid the installation starting up again the next time the system restarts. Otherwise, existing
network settings will be erased at the next start.
In addition, administrators can limit the bandwidth used by a VPort 2140 Video Server according
to priority and importance of location. Limiting bandwidth is useful for balancing network
utilization when multiple VPorts are installed on the same network. This method is more effective
than just changing image quality, and is able to achieve better performance with adequate image
size and quality.
HTTP
For security or network integration, administrators can hide the server from the general HTTP port
by changing the default HTTP port of 80 to a different port number. Administrators should have
enough network knowledge to change the default port.
SMTP
VPort 2140 Video Server not only plays the role of server, but also actively connects to outside
servers to send alarm messages or snapshots. If the administrator has set up some applications in
either event mode or sequential mode, the VPort will send out snapshots once these conditions
occur.
1. To activate the e-mail function, enter correct settings for SMTP (mail) server’s domain
name/IP address and Recipient email address.
2. Secondary SMTP (mail) server’s domain name/IP address and Secondary email address
are provided for a backup connection when the primary SMTP server fail.
3. Return email address is the address the email is returned to when the SMTP server rejects
email due to failure. Some ISPs may reject the email if the address is invalid.
ATTENTION
If the settings are correct when the VPort starts up, it will send out a system log via e-mail
instead of uploading the log via FTP. Note that if the Return email address is not set, the e-mail
system will not work properly.
