applications, also remember to choose Network option to enter mail server address and
recipient's e-mail address. If "Dialout allowed" is not checked, Video Server will not
send out any snapshots when events occur and the settings except for "Initial modem
command" in this page will have no effect. The system will preset the attached modem
to eliminate echo and mute line sound. To initialize the modem with further commands,
type into the edit box. The prefix "AT" should be included.
Administrators should choose an appropriate "Dial Method" according to the local POTS
environment. An incorrect dialing prefix may cause Video Server to fail when dialing out.
"Redial attempts" means how many times Video Server should try to connect to each
ISP. Setting the value in "Disconnect after minutes" will force Video Server to drop the
connection when there is no activity on the connection for the specific period. The range
of this period is from 1 to 240 minutes, with 0 indicating a continuous connection.
Administrators may let Video Server keep the connection for a while to allow connections
from outside. The IP address given by the ISP can be taken from the connection log that
is mailed or uploaded when dial-up connection is successful. Setting the value to zero will
make Video Server always keep the connection.
Based on the settings of DI/DO in the application, the system will send mails or upload
via FTP with image attachment upon the event occurring. In that case Video Server will
need a network connection and automatically dial out to the pre-configured server
outside. When a connection is successfully established, Video Server will send out a
connection log to notify given network settings. For those installations that may switch
the network interface between Ethernet and PPP, administrators should notice that the
settings of FTP or SMTP servers might be different from what are in an Ethernet
environment. If the network interface is changed, administrators may need to configure
them in advance.
Video Server will try the second ISP as a backup when the first ISP fails and exceeds the
redial attempts. "ISP phone number" should be the complete phone number including
country code and area code if necessary. "Login username" and "Login password"
are used to pass the PPP negotiation requested by the ISP server. Note that the pair of
login name and password is dependent on the ISP and is different from what is used in
the authentication process in web access.
