NAME
motion - Detect motion using a video4linux device
SYNOPSIS
motion [ -hmns ] [ -c config file path ] [ -d log level ] [ -k log type ] [ -p process_id_file ] [ -l
logfile ]
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/motion 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.
-m Disable motion detection at startup.
-n Run in non-daemon mode.
-s Run in setup mode. Also forces non-daemon mode
-d log level
Set log level [1..9] (EMR, ALR, CRT, ERR, WRN, NTC, INF, DBG, ALL). (default: 6 / NTC)
-k log type
Set type of log (COR, STR, ENC, NET, DBL, EVT, TRK, VID, ALL). (default: ALL)
-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.
-l Full path and filename of log file. ( use -l syslog to log to stderr and syslog )
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).

SIGUSR1
Motion will create a 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.
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/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 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 webcontrol 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.
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, picture_filename, movie_filename, timelapse_filename,
on_area_detected, on_camera_lost, on_event_start, on_event_end, on_picture_save, on_movie_start,
on_movie_end, and on_motion_detected.
In text_left and text_right you can additionally use '\n' for new line.
%a The abbreviated weekday name according to the current locale.
%A The full weekday name according to the current locale.
%b The abbreviated month name according to the current locale.
%B The full month name according to the current locale.
%c The preferred date and time representation for the current locale.
%C Text defined by the text_event feature
%d The day of the month as a decimal number (range 01 to 31).
%D Number of pixels detected as Motion. If labelling is enabled the number is the number of pixels in
the largest labelled motion area.
%E Modifier: use alternative format, see below.
%f File name - used in the on_picture_save, on_movie_start, on_movie_end, and sql_query features.
%F Equivalent to %Y-%m-%d (the ISO 8601 date format).
%H The hour as a decimal number using a 24-hour clock (range 00 to 23).
%i Width of the rectangle containing the motion pixels (the rectangle that is shown on the image when
locate_motion is on).
%I The hour as a decimal number using a 12-hour clock (range 01 to 12).
%j The day of the year as a decimal number (range 001 to 366).
%J Height of the rectangle containing the motion pixels (the rectangle that is shown on the image
when locate_motion is on).
%k The hour (24-hour clock) as a decimal number (range 0 to 23); single digits are preceded by a
blank. (See also %H.)
%K X coordinate in pixels of the center point of motion. Origin is upper left corner.
%l The hour (12-hour clock) as a decimal number (range 1 to 12); single digits are preceded by a
blank. (See also %I.)
%L Y coordinate in pixels of the center point of motion. Origin is upper left corner and number is
positive moving downwards (I may change this soon).
%m The month as a decimal number (range 01 to 12).
%M The minute as a decimal number (range 00 to 59).
%n Filetype as used in the on_picture_save, on_movie_start, on_movie_end, and sql_query features.
%N Noise level.
%o Threshold. The number of detected pixels required to trigger motion. When threshold_tune is 'on'
this can be used to show the current tuned value of threshold.
%p Either 'AM' or 'PM' according to the given time value, or the corresponding strings for the
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
the filename if you save more then 1 picture per second to ensure unique filenames. It is not
needed in filenames for movies.
%Q Number of detected labels found by the despeckle feature
%r The time in a.m. or p.m. notation.
%R The time in 24-hour notation (%H:%M).
%s The number of seconds since the Epoch, i.e., since 1970-01-01 00:00:00 UTC.
%S The second as a decimal number (range 00 to 61).
%t Thread number (camera number)
%T The time in 24-hour notation (%H:%M:%S).
%u The day of the week as a decimal, range 1 to 7, Monday being 1. See also %w.
%U The week number of the current year as a decimal number, range 00 to 53, starting with the first
Sunday as the first day of week 01. See also %V and %W.
%v Event number. An event is a series of motion detections happening with less than 'gap' seconds
between them.
%V The ISO 8601:1988 week number of the current year as a decimal number, range 01 to 53, where week
1 is the first week that has at least 4 days in the current year, and with Monday as the first day
of the week. See also %U and %W.
%w The day of the week as a decimal, range 0 to 6, Sunday being 0. See also %u.
%W The week number of the current year as a decimal number, range 00 to 53, starting with the first
Monday as the first day of week 01.
%x The preferred date representation for the current locale without the time.
%X The preferred time representation for the current locale without the date.
%y The year as a decimal number without a century (range 00 to 99).
%Y The year as a decimal number including the century.
%z The time-zone as hour offset from GMT.
%Z The time zone or name or abbreviation.
