Image processing enables Home Assistant to process images from [cameras](/components/#camera). Only camera entities are supported as sources.
|
|
|
|
For interval control, use `scan_interval` in platform.
|
|
|
|
<p class='note'>
|
|
If you are running Home Assistant over SSL or from within a container, you will have to setup a base URL (`base_url`) inside the [http component](/components/http/).

## {% linkable_title ALPR %}
|
|
|
|
ALPR entities have a vehicle counter attribute `vehicles` and all found plates are stored in the `plates` attribute.
|
|
|
|
The `found_plate` event is triggered after OpenALPR has found a new license plate.
|
|
|
|
```yaml
|
|
# Example configuration.yaml automation entry
|
|
automation:
|
|
- alias: Open garage door
|
|
trigger:
|
|
platform: event
|
|
event_type: image_processing.found_plate
|
|
event_data:
|
|
entity_id: openalpr.camera_garage_1
|
|
plate: BE2183423
|
|
...
|
|
```
|
|
|
|
The following event attributes will be present (platform-dependent): `entity_id`, `plate`, `confidence`
|
|
|
|
## {% linkable_title Face %}
|
|
|
|
Face entities have a face counter attribute `total_faces` and all face data is stored in the `faces` attribute.
|
|
|
|
The `detect_face` event is triggered after a Face entity has found a face.
|
|
|
|
```yaml
|
|
# Example configuration.yaml automation entry
|
|

|
|
- alias: Known person in front of my door
