Modem and dialup settings

In PPP interface, a modem option will work instead of camera control. 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
