What are Motion and Viseron?
Motion
Motion is a program that monitors video signals from cameras and detects movement. It can record video, capture snapshots, and trigger external scripts when motion is detected, all with a small footprint.
- Motion detection
- Snapshot and video capture
- External script triggers
- Very low resource use
Viseron
Viseron is a self-hosted, local-only network video recorder with built-in object detection and face recognition. It is designed to keep all processing on your own hardware without cloud dependencies.
- Local AI object detection
- Face recognition
- Hardware acceleration support
- Cloud-free operation
Motion vs Viseron: key differences
Motion is written in C++, while Viseron is built with Python. Licensing differs — GPL-2.0 for Motion versus MIT for Viseron. Motion is the lighter option, starting around 256 MB of RAM against 2,048 MB for Viseron. Motion is the more established project (first released 2000), while Viseron arrived in 2020.
