<p />
<h3><a name="What_is_Motion"></a><a name="What_is_Motion_"></a> What is Motion? </h3>
Motion is a program that monitors the video signal from one or more cameras and is able to detect if a significant part of the picture has changed. Or in other words, it can detect motion.
<p />
The program is written in C and is made for the Linux operating system.
<p />
Motion is a command line based tool. It has absolutely no graphical user interface. Everything is setup either via the command line or via a set of configuration files (simple ASCII files that can be edited by any ASCII editor).
<p />
The output from motion can be:
<p /> <ul>
<li> jpg files 
</li> <li> ppm format files 
</li> <li> mpeg video sequences
</li></ul> 
<p />
<h3><a name="How_do_I_get_Motion_and_what_doe"></a> How do I get Motion and what does it cost? </h3>
Motion is an open source type of project. It does not cost anything. Motion is published under the <a href="http://www.gnu.org/licenses/gpl.html" rel="nofollow" target="_top">GNU GENERAL PUBLIC LICENSE</a> (GPL) version 2 or later. It may be a bit difficult to understand all the details of the license text (especially if your first language is not English). It means that you can get the program, install it and use it freely. You do not have to pay anything and you do not have to register anywhere or ask the author or publisher for permission. The GPL gives you both rights and some very reasonable duties when it comes to copying, distribution and modification of the program. So in very general terms you do not have to worry about licensing as a normal hobby user. If you want to use Motion in a commercial product, if you want to distribute either modified or original versions of Motion - for free or for a fee, you should read the license carefully. For more information about free software and the GPL, I encourage you to study the very interesting documents about the subject available the of the Free Software Foundation pages about the <a href="http://www.gnu.org/philosophy/philosophy.html" rel="nofollow" target="_top">Philosophy of the GNU Project</a>.

<h3><a name="Maintenance_and_Support"></a> Maintenance and Support </h3>
Both Motion and the Motion Guide are written by people that do all this as a hobby and without asking for any payments or donations. We have a life other than developing Motion and its documentation. This means that bugfixes and updates to this guide are done as our time and families allow it. You are however encouraged to participate and contribute in a very active <a href="http://motion.sourceforge.net/mailinglist.php" rel="nofollow" target="_top">mailing list</a>. It is a list with a very "positive attitude" and with many contributors that propose features, post patches, discuss problems and patiently answer newbie questions with a very positive spirit. Expect 1-10 emails per day.
<p />
