Troubleshoot QR Code Scanning
Introduction
In AR 3S Pro
Cloud 2022.0.0.0 we introduced the new feature to connect the Client to the
Server by scanning a QR code provided by
the AR 3S Pro Cloud Portal.
In this
article we will tell you how to set up you HoloLens' camera in case the scanning does
not work.

Spoiler Alert: Not only do you need to allow access to the camera but
also allow access to the microphone.
Let's get started
First let’s navigate to the Settings Menu
From there
we want to go to the Privacy Settings
Changing the Privacy Settings
In the Privacy
Settings, select the Camera tab from the left side menu.
Make sure
both options “Allow access to the camera on this device” and “Allow apps to
access your camera” are enabled.
In the same
tab scroll down the List “Choose which apps can access your camera” until you find
AR 3S Pro Cloud Client.
Make sure AR 3S Pro Cloud Client.
Finally
open the Microphone tab.
Enable “Allow access to the microphone on this
device” and “Allow apps to access your microphone”.

Although these
two options are labeled as microphone settings, they are necessary for the
camera.
