Serial Port Names


Are things like /dev/ttys0.

Killing Motion or Reloading Config File

kill -s SIGHUP pid # Reloads the config file.
kill -s SIGTERM pid # Captures the last event and quits.

Installing Motion

First installed Apache / MySQL / PHP 5 (see previous post).

Next do the preparation.

% sudo apt-get install libc6 libc6-dev libglib1.2 libjpeg62 libjpeg62-dev zlib1g zlib1g-dev


Note that Ubuntu packages will be the same as the Debian ones. So make sure they're all installed. Note that a bunch (especially the non dev packages) will already be installed.

Next follow the installation instructions here:


Everything worked for me except the instructions lie about the placement of the default configuration file. The installation script doesn't lie, however, so use that location. The one I'm using ended up here:


I made the modifications they suggested hooking it up to /dev/video1. And it worked like a charm. Plopped data down into /var/www/camera/ like I configured it to.

Installing VLC (w/ GUI) for Quickcam 4000

% sudo apt-get install vlc vlc-plugin-esd mozilla-plugin-vlc

Now run vlc

% vlc

File -> "Open Capture Device" and set "Video device name" to "/dev/video0". Hit "OK" and you should see the video from the webcam appear on screen. If you want the source data bigger go ahead and click "Advanced Options" and increase it to 352w x 288h.
