The `facebox` image processing platform allows you to detect and recognize faces in a camera image using [Facebox](https://machinebox.io/docs/facebox). The state of the entity is the number of faces detected, and recognized faces are listed in the `matched_faces` attribute. An `image_processing.detect_face` event is fired for each recognized face, and the event `data` provides the `confidence` of recognition, the `name` of the person, the `image_id` of the image associated with the match, the `bounding_box` that contains the face in the image, and the `entity_id` that processing was performed on.
|
|
|
|
## {% linkable_title Setup %}
|
|
|
|
Facebox runs in a Docker container and it is recommended that you run this container on a machine with a minimum of 2 GB RAM. On your machine with Docker, run the Facebox container with:
|
|
|
|
```bash
|
|
MB_KEY="INSERT-YOUR-KEY-HERE"
|
|
|
|
sudo docker run --name=facebox --restart=always -p 8080:8080 -e "MB_KEY=$MB_KEY" machinebox/facebox
|
|
```
|
|
|
|
If you only require face detection (number of faces) you can disable face recognition by adding `-e "MB_FACEBOX_DISABLE_RECOGNITION=true"` to the `docker run` command.
|
|
|
|
## {% linkable_title Configuration %}
|
|
|
|
To enable this platform in your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
image_processing:
|
|
- platform: facebox
|
|
ip_address: 192.168.0.1
|
|
port: 8080
|
|
source:
|
|
- entity_id: camera.local_file
|
|
name: my_custom_name
|
|
```
|
|
|
|
{% configuration %}

|
|
{% endconfiguration %}
|
|
|
|
## {% linkable_title Automations %}
|
|
|
|
Use the `image_processing.detect_face` events to trigger automations, and breakout the `trigger.event.data` using a [data_template](https://www.home-assistant.io/docs/automation/templating/). The following example automation sends a notification when Ringo Star is recognized:
|
|
|
|
{% raw %}
|
|
```yaml
|
|
- id: '12345'
|
|
alias: Ringo Starr recognised
|
|
trigger:
|
|
platform: event
|
|
event_type: image_processing.detect_face
|
|
event_data:
|
|
name: 'Ringo_Starr'
|
|
action:
|
|
service: notify.platform
|
|
data_template:
|
|
message: Ringo_Starr recognised with probability {{ trigger.event.data.confidence }}
|
|
title: Door-cam notification
|
|
```
|
|
{% endraw %}
|
|
|
|
## {% linkable_title Optimising resources %}
|
|
|
|
[Image processing components](https://www.home-assistant.io/components/image_processing/) process the image from a camera at a fixed period given by the `scan_interval`. This leads to excessive processing if the image on the camera hasn't changed, as the default `scan_interval` is 10 seconds. You can override this by adding to your config `scan_interval: 10000` (setting the interval to 10,000 seconds), and then call the `image_processing.scan` service when you actually want to perform processing.
