COM2 port configuration and modem

Choose device driver

There are three types of device drivers that can be attached to COM2. The modem is

supported by COM2 more than COM1 but only RS232 interface is supported.

Administrators should select the device driver and click on save, then the related

configuration will show in the lower half of the page. If the modem is selected, ISP

information is necessary.

COM port configuration

After saving the driver type, the COM port configuration will show up for entering the

correct settings that depends on the camera type. Refer to the Appendix Settings for

Supported PTZ Cameras for default settings of supported PTZ camera including baud

rate, data bits, stop bit and parity bit.

Custom commands

will appear when administrators select PTZ driver. The usage is similar

to COM1. If administrators select “Modem”, refer to the next paragraph for details.

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, 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
