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; in other words, it can detect motion.
The program is written in C and is made for the Linux operating system. Motion is a command line based tool whose output can be either jpeg, ppm fies or mpeg video sequences. Motion is strictly command line driven and can run as a daemon with a rather small footprint.
Motion is the perfect tool for keeping an eye on your property, keeping only those images that are interesting.
