DreamPlug: motion activated webcam

The webcam tool 'motion' is pretty nice, but it needs some tweaks to the base Ubuntu/Jaunty running the DreamPlug.

Do this:

  • Enable the motion daemon. sudo emacs /etc/default/motion and set start_motion_daemon=yes

  • Allow for non-localhost access to the web interfaces. sudo emacs /etc/motion/motion.conf and change the lines to match: webcam_localhost off and control_localhost off

  • Create the default directory to hold the jpg and swf files. sudo mkdir /tmp/motion && sudo chown motion.motion /tmp/motion

  • Restart the motion daemon. sudo /etc/init.d/motion restart

  • Fire up a browser and point it to the DreamPlug's port 8080 (say http://morpheus.local:8080) and then follow the link to config then list. From there you'll probably need to set auto_brightness to on.

  • Now look at the video on port 8081 (say http://morpheus.local:8081)

After a while of it running, you don't need the browser to be on the page, take a look in /tmp/motion to find all the JPG images and SWF 'movie' files. Eventually I'll probably change the directory to live on one of the USB disks...

  1. Were there any issues with camera resolution on the dreamplug? raspberry pi seems to only be able to swing the lowest camera resolution through a usb hub with motion
