Motion (surveillance software)
Motion, a software motion detector, is a free software CCTV software application developed for Linux.
Motion is a highly configurable program that monitors video signals from many types of cameras. Set it up to monitor your security cameras, watch birds, check in on your pet, create timelapse videos and more. It can monitor video signal from one or more cameras and is able to detect if a significant part of the picture has changed saving away video when it detects that motion is occurring.
The program is written in C and is made for Linux. Motion is a command line-based tool whose output can be either jpeg, netpbm files or mpeg video sequences. It is strictly command line driven and can run as a daemon with a rather small footprint and low CPU usage.
It is operated mainly via config files, though the end video streams can be viewed from a web browser.
It can also call to user configurable "triggers" when certain events occur. Starting with version 4.2, the motion daemon supports encryption with Transport Layer Security.
