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 Network Camera 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 Network Camera 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 Network Camera will need a network connection
and automatically dial out to the pre-configured server outside. When a connection is successfully
established, Network Camera 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 is in an Ethernet
environment. If the network interface is changed, administrators may need to configure them in advance.
Network Camera 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, Network Camera 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.
