## What it is
Motion is an open-source C++ program that monitors video camera signals and detects changes (motion) in the images. It is commonly used for surveillance and security camera setups on Linux systems.

## Use cases
- detect motion from security cameras
- monitor webcam for movement
- set up a DIY CCTV system
- record video when motion is detected
- home surveillance software
- watch IP cameras for activity

## When to choose
- you need lightweight, self-hosted motion detection on Linux
- you want to record or trigger actions on camera motion without a full NVR suite
- you prefer a mature GPL-licensed command-line tool with long history

## When to avoid
- you need a polished multi-camera NVR with a modern web UI out of the box
- you require deep-learning-based object detection rather than pixel-change motion detection
- you need a Windows-native or GUI-first application

## Facets
- artifact type: application
- maturity: active
- function: computer-vision, video-processing, monitoring
- domain: security, computer-vision, self-hosted
- platform: cross-platform, cli
