DVR-Scan is a command-line application that automatically detects motion events in video files (e.g. security camera footage). DVR-Scan looks for areas in footage containing motion, and saves each event to a separate video clip. DVR-Scan is free and open-source software, and works on Windows, Linux, and Mac.

pip install dvr-scan --upgrade

Windows builds (installer + portable) are also available on the Downloads page.
