I have a Surface Pro 6 with a Windows Hello integrated infrared camera. Months ago, while using app.houseparty.com, a video calling service that has since been shut down, I discovered that it let you change the camera source to the IR camera, called "Microsoft IR Camera Front," and it would turn on the flashing IR light (hurt my eyes a bit) and show the funny camera feed like this (not my face, from here). But now the website is gone, and I can't find any other software that can see the camera. "Microsoft IR Camera Front" appears in Device Manager as a System Device, along with the main front and back camera.
I was wondering if there was any way to get the camera image directly or if there were any software that would see the camera. This use isn't urgent or extensive, I just think it would be funny.
