connection for the specific period. The range of this period is from 1 to 240 minutes, with 0 indicating a
continuous connection. Administrator may let the 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 the Video
Server always keep the connection.
Based on the settings of DI/DO in the application, the system will send mail or upload via FTP with
image attachment upon the event occurring. In that case the Video Server will need a network connection
and automatically dial out to the pre-configured server outside. When a connection is successfully
established, the 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, Administrator should
notice that the settings of FTP or SMTP servers might be different from what is in an Ethernet
environment. If the network interface is changed, Administrator may need to configure them in advance.
The 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.
When using modem as the network connection, the Video Server will mute the audio
automatically, and send video only because the low bandwidth environment doesn’t meet the
requirement for both. In the Client setting page, protocol option will be set as Http protocol.
