ISP information setup
In PPP interface, a modem option will show instead of camera control 2. Configurations
include modem initialization and outside dial-up server. If the users will setup with
external sensors and alarms for property security, dial-out is needed to send some
snapshot-attached e-mails when the preset conditions are triggered. In such
applications, also remember to choose Network option to enter mail server address and
recipient's e-mail address. If "Dialout allowed" is not checked, Network Camera 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 Network Camera to fail when dialing
out. "Redial attempts" means how many times Network Camera should try to connect
to each ISP. Setting the value in "Disconnect after minutes" will force Network
Camera 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 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 mails 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 are 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
