Camera enable_motion_detection unknown error / unimplemented

hi folks,

still quite new to HA, but still enjoying exploring :slight_smile:

Am trying to control my cameras via HA. I can do everything perfectly via the HA GUI, but switching the motion detection on/off via a script seems difficult. Maybe I’m missing something obvious? If I use the devel tools service call and run this snippet:

service: camera.enable_motion_detection
data: {}
  entity_id: camera.camera2

Then I get an “Unknown error”, which actually transposes to the following in the system logs:

Logger: homeassistant.helpers.script.websocket_api_script
Source: components/camera/
First occurred: 9:34:41 AM (3 occurrences)

    result = self.fn(*self.args, **self.kwargs)

    raise NotImplementedError()

Not sure, what’s quite wrong here. Unimplemented seems a strange thing for the core camera functionality to respond with, perhaps it’s the hardware, how to know? The Camera is an Imou Bullet.

I appreciate any helpful suggestions…
