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".
