[Motion][1] 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. Or in
other words, it can detect motion.

## docker-compose.yml

```yaml
motion:
  image: easypi/motion-arm
  ports:
    - "8080:8080"
    - "8081:8081"
  volumes:
    - ./motion.conf:/etc/motion/motion.conf
    - ./data:/var/lib/motion
    - /etc/localtime:/etc/localtime
  devices:
    - /dev/video0:/dev/video0
  restart: always
```

You can edit `motion.conf` to customize motion.

```ini
# set image width
width 640

# set image height
height 480

# set frame rate
framerate 5

# disable image output
output_pictures off

# disable video output
ffmpeg_output_movies off

# encode timelapse movie
ffmpeg_timelapse 60
```

Motion can work with Home-Assistant via [External Commands][2].

``yaml
binary_sensor:
  - platform: mqtt
    name: Motion
    state_topic: /pi/sensor/motion
    qos: 0
    payload_on: ON
    payload_off: OFF
    device_class: motion
```

```bash
# Command to be executed when a movie file (.mpg|.avi) is created. (default: none)
# To give the filename as an argument to a command append it with %f

# MQTT

```
