NAME

       motion -   Detect motion using a video4linux device

SYNOPSIS

       motion [ -hns ] [ -c config file path ] [ -d level ] [ -p process_id_file ]

DESCRIPTION

       Motion  uses a video4linux device to detect motion. If motion is detected both normal and motion pictures
       will be taken. Motion can also take actions to notify you if needed. Creation of automated  snapshots  is
       also possible.

OPTIONS

       -c     Full  path  and  filename  of  config file. E.g. /home/kurt/motion.conf. Default is /usr/local/etc
              unless specified differently when building Motion. Many RPMs and debian packages will most  likely
              use /etc or /etc/motion as default.

       -h     Show help screen.

       -n     Run in non-daemon mode.

       -s     Run in setup mode. Also forces non-daemon mode

       -d level
              Run in debug mode, level 1-9.

       -p     Full  path  and  filename  for process id file (pid file). E.g /var/run/motion.pid. Default is not
              defined. Pid file is only created when Motion is started in daemon mode.

              Values: on, off / Default: off
              Turns the switch filter on or off. The filter can distinguish between  most  switching  noise  and
              real  motion.  With  this  you  can  even  set  roundrobin_skip to 1 without generating much false
              detection.

       target_dir string
              Values: Max 4095 characters / Default: Not defined = current working directory

              ISO format and time in 24 hour clock

       thread string
              Values: Max 4095 characters / Default: Not defined
              Specifies full path and filename for a thread config file. Each camera needs a thread config  file
              containing  the options that are unique to the camera. If you only have one camera you do not need
              thread config files. If you have two or more cameras you need one  thread  config  file  for  each
              camera  in  addition to motion.conf. This option must be placed in motion.conf and not in a thread
              config file.

SIGNALS

       Motion responds to the following signals:

       SIGHUP The config file will be reread.

       SIGTERM
              If needed motion will create an mpeg file of the last event and exit

       SIGUSR1
              Motion will create an mpeg file of the current event.

NOTES

       Snapshot
              A snapshot is a picture taken at regular intervals independently of any movement in the picture.

       Motion image
              A "motion" image/mpeg shows the pixels that have actually changed during the  last  frames.  These
              pictures  are  not very useful for normal presentation to the public but they are quite useful for
              testing and tuning and making mask files as you  can  see  exactly  where  motion  sees  something
              moving.  Motion is shown in greytones. If labelling is enabled the largest area is marked as blue.
              Smart mask is shown in read.

       Normal image
              A "normal" image is the real image taken by the camera with text overlayed.

       Threads and config files
              If Motion was invoked with command line option -c pathname Motion will expect the config  file  to
              be  as  specified.  When  you  specify the config file on the command line with -c you can call it
              anything.
              If you do not specify -c or the filename you give Motion does not exist, Motion  will  search  for
              the configuration file called 'motion.conf' in the following order:
              1. Current directory from where motion was invoked
              2.  Then  in  a  directory called '.motion' in the current users home directory (shell environment
              variable $HOME). E.g. /home/goofy/.motion/motion.conf
              3. The directory defined by the --sysconfdir=DIR when running .configure  during  installation  of
              Motion (If this option was not defined the default is /usr/local/etc/)
              If  you have write access to /usr/local/etc then the editor recommends having only one motion.conf
              file in the default /usr/local/etc/ directory.
              Motion has a configuration file in the distribution package called motion-dist.conf. When you  run
              'make install' this files gets copied to the /usr/local/etc directory.
              The configuration file needs to be renamed from motion-dist.conf to motion.conf. The original file
              is  called  motion-dist.conf so that your perfectly working motion.conf file does not accidentally
              get overwritten when you re-install or upgrade to a newer version of Motion.
              If you have more than one camera you should not try and invoke Motion more times. Motion  is  made
              to work with more than one camera in a very elegant way and the way to do it is to create a number
              of  thread  config files. Motion will then create an extra tread of itself for each camera. If you
              only have one camera you only need the motion.conf file. The minute you have two or  more  cameras
              you must have one thread config file per camera besides the motion.conf file.
              So  if you have for example two cameras you need motion.conf and two thread config files. Total of
              3 config files.
              An option that is common to all cameras can be placed  in  motion.conf.  (You  can  also  put  all
              parameters in the thread files but that makes a lot of editing when you change a common thing).
              An option that is unique to a camera must be defined in each thread file.
              The  first  camera  is defined in the first thread file called from motion.conf. The 2nd camera is
              defined in the 2nd thread file called from motion.conf etc.
              Any option defined in motion.conf will be used for all cameras except for the cameras in which the
              same option is defined in a thread config file.
              Motion reads its configuration parameters in the following sequence. If the same parameter  exists
              more than one place the last one read wins.
              1.  Motion reads the configuration file motion.conf from the beginning of the file going down line
              by line.
              2. If the option "thread" is defined in motion.conf, the  thread  configuration  file(s)  is/(are)
              read.
              3.  Motion continues reading the rest of the motion.conf file. Any options from here will overrule
              the same option previously defines in a thread config file.
              4. Motion reads the command line option again overruling any previously defined options.
              So always call the thread config files in the end of the motion.conf file. If you  define  options
              in  motion.conf  AFTER  the  thread file calls, the same options in the thread files will never be
              used. So always put the thread file call at the end of motion.conf.
              If motion is built without specific features such as ffmpeg, mysql etc it will ignore the  options
              that belongs to these features. You do not have to remove them or comment them out.
              If  you  run  the  http  control command http://host:port/0/config/writeyes, motion will overwrite
              motion.conf and all the thread.conf files by autogenerated config files neatly formatted and  only
              with  the  features  included  that  Motion was built with. If you later re-build Motion with more
              features or upgrade to a new version, you can use your old config files, run the motion.conf.write
              command, and you will have new config files with the new options included all set to their default
              values. This makes upgrading very easy to do.
