Motion

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; in other words, it can detect motion. Motion is the perfect tool for keeping an eye on your property, keeping only those images that are interesting.

LinuxMCE has a wrapper that connects to Motion, called "Motion Wrapper". This wrapper is added as a "device" on the "Interfaces" page. You must have this interface installed before setting up cameras.

The program is written in C for the Linux operating system. Motion is a command line based tool whose output can be jpeg or ppm files, or mpeg video sequences.

For detailed info see the Motion website.

• Take automated snapshots on regular intervals
• Take automated snapshots at irregular intervals using cron
• Execute external commands when detecting movement (and e.g. send SMS or email)
• Motion tracking (camera follow motion - special hardware required)
• Feed events to a MySQL or PostgreSQL database.
• Feed video back to a video4linux loopback for real time viewing
• Lots of user contributed related projects with web interfaces etc.
• User configurable and user defined on screen display.
• Controlled via the browser (older versions used xml-rpc)
• Automatic noise and threshold control
• Motion is a daemon with low CPU consumption and a small memory footprint.

Changing the Motion Wrapper settings

• LinuxMCE Admin Website-->Show Devices Tree
• My Devisces-->CORE-->Motion Wrapper
• Under Device Data-->Motion Parameters can be found the actual parameters. The correspond to the http://www.lavrsen.dk/twiki/bin/view/Motion/ConfigFileOptions<//nowiki> Motion config options] found on the Motion wiki. ==Compiling (contributing) to Motion Wrapper in LinuxMCE== In version 0.41 of LinuxMCE I wanted to incorporate a few changes into Motion wrapper. I decided to compile it and described the procedure [[How_to_compile_Motion_Wrapper|here]]. ==Interesting related projects== Since there will probably be some discussion about the future of video surveillance under LinuxMCE, I'll enumerate here few interesting projects... *[http://www.lavrsen.dk/twiki/bin/view/Motion/KmotionWebViewer Kmotion Web Viewer] *[http://www.zoneminder.com/ Zoneminder]
