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.
Features
- Takes snapshots of movement
- Watches multiple video devices at the same time
- Watches multiple inputs on one capture card at the same time
- Live streaming webcam (using multipart/x-mixed-replace)
- Real time creation of mpeg movies using libraries from ffmpeg
- 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--> Advanced --> Devices
- My Devices-->CORE-->Motion Wrapper
- Under Device Data-->Motion Parameters can be found the actual parameters. The correspond to the Motion config options found on the Motion wiki.
- My surveillance camera already has automatic light leveling and I don't need the Motion module to do it for me, so I set auto-brightness off.
- I wanted my camera to detect movement when just two frames showed a difference, so I set minimum_motion_frames to 2.
- also need to set snapshot_interval to 2 (snapshot_interval 2)
- After making all my changes, I saved and did a quick reload router.
Since there will probably be some discussion about the future of video surveillance under LinuxMCE, I'll enumerate here few interesting projects, which I hope will one day be incorporated into LinuxMCE.
