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.

       switchfilter boolean
              Values: on, off / Default: off
              Turns the switch filter  on  or  off.  The  filter  can  distinguish  between  most

              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.

       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.
