Motion

Introduction

Motion is a program that monitors the video signal from cameras. It is able to detect if a significant part of the picture has changed; in other words, it can detect motion.

Installation

Gentoo Linux

Even though 'motion' is in the Portage tree, you will need to download and use the svn ebuild, because the official ebuilds do not work with the latest kernels, specifically the 'v4l' drivers.

You can use Motion to capture movement in an RTSP stream from a cheap wi-fi camera like this one...

http://wiki.indie-it.com/wiki/Security#V380_Shenzhen_Trolink_Technology

Create your configuration folder and copy the master settings file...

mkdir /tmp/cam1
mkdir ~/.motion
sudo cp /etc/motion/motion.conf ~/.motion/
nano ~/.motion/motion.conf

Comment out the videodevice setting and add the stream settings...

target_dir /tmp/cam1
# videodevice /dev/video0
netcam_url rtsp://192.168.0.165:554/mpeg4
netcam_userpass admin:password

Run motion pointing to the configuration file...

motion -c ~/.motion/motion.conf
