Hello,

By default, Vuforia Engine SDK will select the back camera that is typically used for photos, i.e. not the wide-angle camera, nor the telephoto camera.

Currently, Vuforia Engine APIs do not allow for the selection of other cameras. However, in theory, this could be created by using Engine's External Camera Support.

One thing to be aware of is that the lens properties of the wide-angle and/or telephoto cameras can impact Engine SDK's tracking performance due to the camera frame distortions that are introduced. When using External Cameras, this can be accounted for with external camera calibration.

Kind regards,

Dave Downing
