Telnet Commands

Network Camera has a Telnet daemon for only administrators to access some seldom

used functions. Using any general terminal program to connect to Network Camera will

prompt the user for a password. Username is not requested here since only

administrators can access the Telnet daemon. The password is as same as that used in

web access. After logging in, type "help" for the command list. If "debug" or "dinote" is

not executed, Telnet will disconnect automatically after being idle for 1 minute.

System core debugging

General activities are recorded into SYSTEM.LOG continuously, but information about

abnormal status is not. To look deep into the core debugging information, administrators

may type the “debug” command. This will cause Network Camera to start dumping the

detailed debugging information while the system is running. This is useful to examine if

any error has occurred when the system operates abnormally. The stored information

will be cleared automatically after the dump. Network Camera will continue to dump new

messages unless the connection is broken. If Telnet is not connected, any messages will

be stored until administrators re-login.

Monitor changed status of digital input

Typing "dinote" will make Network Camera send the current status of digital input. After

that Network Camera will continuously monitor DI status and send messages only when

the state has changed. For example, after typing "dinote" the terminal will display

DI1=L

and after DI1 changes to H, terminal will display

DI1=H

Stop information dumping

Typing "stop" will cease dumping debug information and the digital input status.

Query status of digital input

Typing "diquery" will display the status of all digital input once.

Set digital output

To set digital output to connect NO with COMMON, type "DO1=L".

To set digital output to connect NC with COMMON, type "DO1=H".
