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.

General options:
 -v, --verbose                           - Produce more verbose output
 -l, --list                              - List the current status of active (or all with -v) monitors
 -h, --help                              - Display usage information
 -v, --version                           - Print the installed version of ZoneMinder

Options for use with devices:
 -d, --device [device_path]              - Get the current video device settings for [device_path] or all devices
 -V, --version <V4L version>             - Set the Video 4 Linux API version to use for the query, use 1 or 2
 -q, --query                             - Query the current settings for the device

Options for use with monitors:
 -m, --monitor <monitor_id>              - Specify which monitor to address, default 1 if absent
 -q, --query                             - Query the current settings for the monitor
 -s, --state                             - Output the current monitor state, 0 = unknown, 1 = idle, 2 = prealarm,
                                           3 = alarm, 4 = alert, 5 = tape
 -B, --brightness [value]                - Output the current brightness, set to value if given
 -C, --contrast [value]                  - Output the current contrast, set to value if given
 -H, --hue [value]                       - Output the current hue, set to value if given
 -O, --colour [value]                    - Output the current colour, set to value if given
 -i, --image [image_index]               - Write captured image to disk as <monitor_name>.jpg, last image captured
                                           or specified ring buffer index if given.
 -S, --scale <scale_%%ge>                - With --image specify any scaling (in %%) to be applied to the image
 -t, --timestamp [image_index]           - Output captured image timestamp, last image captured or specified
                                           ring buffer index if given
 -R, --read_index                        - Output ring buffer read index
 -W, --write_index                       - Output ring buffer write index
 -e, --event                             - Output last event index
 -f, --fps                               - Output last Frames Per Second captured reading
 -z, --zones                             - Write last captured image overlaid with zones to <monitor_name>-Zones.jpg
 -a, --alarm                             - Force alarm in monitor, this will trigger recording until cancelled with -c
 -n, --noalarm                           - Force no alarms in monitor, this will prevent alarms until cancelled with -c
 -c, --cancel                            - Cancel a forced alarm/noalarm in monitor, required after being enabled with -a or -n
 -L, --reload                            - Signal monitor to reload settings
 -E, --enable                            - Enable detection, wake monitor up
 -D, --disable                           - Disable detection, put monitor to sleep

 -U, --username <username>               - When running in authenticated mode the username and
 -P, --password <password>               - password combination of the given user
 -A, --auth <authentication>             - Pass authentication hash string instead of user details
 -x, --xtrigger                          - Output the current monitor trigger state, 0 = not triggered, 1 = triggered
