{% hint style="info" %}
The *Camera (ML Kit)* parameters only apply when Kalipso scans with the camera using ML Kit, which is the default unless changed in the [Android Camera Scan Mode](/kalipso/documentation/project/properties/other.md) project property. This happens with [Barcode Scan](/kalipso/documentation/actions/group-barcode/barcode-scan.md) without **BarcodeConnect** or with [Camera Set Preview](/kalipso/documentation/actions/group-others/camera-set-preview.md).

These parameters have no default values, so you must set all the ones you need.
{% endhint %}

### Example

To read two barcodes at once with the camera, separated by ENTER. Barcode Scan only returns after finding two barcodes:
