 So what is a **Data Stream**? Simply put, it's a connection that will stream data from your app to Google Analytics. You can have multiple **Data Streams** in your **Property**, but in most cases you will only need one.
 
-Let's set up our first **Data Stream**. As Noodl outputs Web Apps, we will need to select the [**Web** option](https://support.google.com/analytics/answer/9304153#stream&zippy=%2Cweb). When asked for the URL of the primary website, this needs to be the URL for your app [when it's deployed](/docs/guides/deploy/deploying-an-app-on-sandbox). `example.com` works for testing purposes as well.

 # Scanning for QR Codes in a camera feed
 
 This example enables you to scan a camera feed for Quick Response (QR) Codes and fetch the resulting data in the QR Code. To scan for QR Codes via uploaded images, see the documentation on the [Image QR Scanner](/library/modules/qr-scanner/guides/image-upload).

 ## No camera stream in viewer? HTTP vs. HTTPS
 
 For security reasons, the camera feed can generally only be accessed through a secure connection, i.e. an URL beginning with <code>https://</code>, and not <code>http://</code>. This means that on some platforms (depending on OS and browser) the camera feed of the **Camera QR Scanner** will not work inside of the Noodl viewer. Furthermore, connecting to http://localhost:8574/ might have the same issue. However, on some platforms localhost is exempted from the rule and the camera works without problems in the viewer.
-If you run into this problem you will have to deploy to a secure server via <code>https://</code>. The easiest way to do that is to use the [Noodl Sandbox Deploy](/docs/guides/deploy/deploying-an-app-on-sandbox) which uses <code>https://</code> protocols.
