Configure a Fake Camera

A fake camera is a camera model for testing. The camera always returns the same image, which is an image of a gradient. This camera also returns a point cloud.

You can optionally specify a height and width.

Navigate to the Config tab of your robot’s page in the Viam app. Click on the Components subtab and click Create component. Select the camera type, then select the fake model. Enter a name for your camera and click Create.
