zmc(8) The ZoneMinder Utility


zmu -d device_path [-v] [function] [-U<username> -P<password>]
zmu --device device_path [-v] [function] [-U<username> -P<password>]
zmu -m monitor_id [-v] [function] [-U<username> -P<password>]
zmu --monitor monitor_id [-v] [function] [-U<username> -P<password>]


This binary is a handy command line interface to several useful functions. It's not really meant to be used by anyone except the web page (there's only limited 'help' in it so far) but can be if necessary, especially for debugging video problems.
