Telnet
Network Camera has a Telnet daemon for 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 for 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 inputs
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
DI=L
DI=L
and if DI changes to H, terminal will display only
DI=H
Stop information dumping
Typing "stop" will cease dumping debug information and digital input status.
Query status of digital inputs
Typing "diquery" will display the status of digital input once.
