NAME
motion - Detect motion using a video4linux device or network camera
SYNOPSIS
motion [ -hbnsm ] [ -c config file path ] [ -d level ] [ -k level ] [ -p pid_file ][ -l log_file ]
DESCRIPTION
Motion uses a video4linux device or network camera to detect motion. If motion is detected both normal
and motion pictures can 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. For example: /home/kurt/motion.conf The default is
/usr/local/etc/motion unless specified differently when building Motion. Many RPMs and Debian
packages will use /etc or /etc/motion as the default.
-h Show help screen.
-b Run in daemon mode.
-n Run in non-daemon mode.
-s Run in setup mode. Also forces non-daemon mode.
-d Run with message log level 1-9.
-k Run with message log type 1-9.
-l Full path and file name for the log file.
-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.
-m Start in pause mode.
CONFIG FILE OPTIONS
These are the options that can be used in the config file. They are overridden by the
commandline! All number values are integer numbers (no decimals allowed). Boolean options can be
on or off (values "1", "yes" and "on" all means true and any other value means false).

camera_id
Values: Numeric identification number for the camera
Default: The order in which the camera is opened by Motion
Description:
Use this option to assign a number to each camera that is consistent every time that Motion

reads the configuration and this sequence may not be the same every time that Motion
starts.
camera
Values: User specified string
Default: Not Defined
Description:
This option specifies the full path and file name to individual camera files. This option

to that camera/video device. Common options are obtained from the motion.conf file and
values are overwritten from each camera file. While the motion.conf includes four sample
camera files, the actual limit of cameras is only dependent upon the machine capabilities.
Remember: If you have more than one camera you must have one camera file for each one. For
example, 2 cameras would require 3 files: The motion.conf file AND camera1.conf and
camera2.conf. only put the options that are unique to each camera in the camera config
files.

SIGNALS
Motion responds to the following signals:
SIGHUP The config file will be reread.
SIGTERM
If needed motion will create an movie file of the last event and exit
SIGUSR1
Motion will create an movie 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/movie 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.
Cameras 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 motion/ subdirectory inside 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/motion then the editor recommends having only one
motion.conf file in the default /usr/local/etc/motion 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/motion 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 camera config files. Motion will then create an extra thread 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 camera config file per camera besides the motion.conf file.
So if you have for example two cameras you need motion.conf and two camera 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 camera 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 camera file.
The first camera is defined in the first camera file called from motion.conf. The 2nd camera is
defined in the 2nd camera 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 camera 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 "camera" is defined in motion.conf, the camera 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 camera config file.
4. Motion reads the command line option again overruling any previously defined options.
So always call the camera config files in the end of the motion.conf file. If you define options
in motion.conf AFTER the camera file calls, the same options in the camera files will never be
used. So always put the camera 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 camera.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.
Conversion Specifiers for Advanced Filename and Text Features
The table below shows all the supported Conversion Specifiers you can use in the options
text_left, text_right, snapshot_filename, jpeg_filename, ffmpeg_filename, timelapse_filename,
on_event_start, on_event_end, on_picture_save, on_movie_start, on_movie_end, and

current locale. Noon is treated as `pm' and midnight as `am'.
%P Like %p but in lowercase: `am' or `pm' or a corresponding string for the current locale.
%q Picture frame number within current second. For jpeg filenames this should always be included in
