I set my synology camera and it shows image in default_view.
camera:
- platform: synology
url: https://xx
username: xx
password: xx
timeout: 15
verify_ssl: False

I want to control the camera in automation. I tried developer tools send a turn_off Service but the camera is still recording.
Dose this service works for synology camera?
