Nest Doorbell Face detection with Facebox

Hi,

has anyone successfully setup a Nest Doorbell (gen 2 battery) to detect faces with Facebox.

  1. Have the Doorbell setup successfully
  2. I have Facebox set up and tested successfully. I used this guide https://siytek.com/home-assistant-face-recognition/)
  3. However, when I switch by config to use the doorbell entity no faces are detected.

My Config:

image_processing:
  - platform: facebox
    ip_address: XXXXXX
    port: XXXX
    source:
          - entity_id: camera.front_door_doorbell
            name: face_detect_front_door

Any pointers would be appreciated!

Thank you.
