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. Or in other words, it can detect motion. Motion is a command line based tool. It has no graphical user interface. Everything is setup via the command line or via a set of configuration files. Optional dependencies are ffmpeg and postgresql. Once installed, please be sure to read /usr/doc/motion-3.2.11/README for any configuration help. You will need to rename /etc/motion-dist.conf to /etc/motion.conf once you have made the changes you deem necessary. This build has not been tested with the optional postgresql included, but you're welcome to give it a go!
