Detect motion (activity)
Using an XO for animal motion detection.
Positioning
Position the XO in a location that will see movement by animals, such as a bird bath, bird nest, or mouse hole. For example, this B1 XO was set in ebook mode and suspended from hooks:
Try to avoid positions with grass or vegetation that may move in the wind, otherwise you'll get pictures of the grass moving.
Software
Not yet packaged for the XO, but a binary package is available, which was built from CVS including the new V4L2 API provided by the XO camera kernel module.
- open a root shell on the XO
- download the binary package
# cd /tmp # wget http://dev.laptop.org/~quozl/motion-2007-03-05.tar.bz2
- unpack it
# cd / # tar xfj /tmp/motion-2007-03-05.tar.bz2 # cd /motion # rm /tmp/motion-2007-03-05.tar.bz2
- edit the motion.conf configuration file according to the documentation at http://www.lavrsen.dk/twiki/bin/view/Motion/ConfigFileOptions ... you may wish to use the full frame size:
width 640 height 480
- start the motion detector
# ./go
- if you change motion.conf while motion is running, send it a SIGHUP so it will reread the file
# killall -HUP motion
- access the webcam view in a web browser, using a URL composed from the IP address or host name, followed by port 8081, for example http://example-xo-1.laptop.org:8081/
