 For Raspberry Pi AI cameras like the IMX500 AI camera, you can use a module such as [this `viam-pi-ai-camera` vision service](https://github.com/HipsterBrown/viam-pi-ai-camera).
 Note that this module is not officially supported by Viam.
 For more information about the vision service, see [run inference](https://docs.viam.com/data-ai/ai/run-inference/).

-If you are getting "timeout" errors from GRPC when adding a `webcam` model on a Raspberry Pi, make sure the webcam port is enabled on the Pi (common if you are using a fresh Pi right out of the box).
-
-To enable the webcam port on a Raspberry Pi, run the following command:
-
-```sh {class="command-line" data-prompt="$"}
-sudo raspi-config
-```
-
-Then, select: **Interface Options -> Camera -> Enable Camera**.
