========================
Detailed description：

I'm trying the Windows login with face using the IR camera on my ZenBook Pro Duo UX581GV and it doesn't seem to work. The whole idea of an IR camera is to handle low illumination, but this one is like bad, really bad. Have a look at the picture. Shouldn't it be grayscale?
It's not able to recognize me at low illumination, so it erases its purpose.

It also makes some weird circles before it gets to that state.

I have 2 identical laptops, bought from different stores, with the same updates and so on. I'm noticing the exact same problem.

Here is a video of the issue.

it seems that I'm not alone in this one, and Asus decided to basically lock the thread and do nothing about it. We're talking here about 3 500 Euro laptops.
