Windows 10: Help with IR camera used by Windows hello

Hello, I have a Lenovo Thinkpad P53 laptop with an integrated camera. Under device manager I can see an integrated camera and an Integrated IR camera. Up to about a month ago I was able to use the hello login with face recognition without any trouble. I was getting a RED led blinking beside my camera when I was logging in. Now when I start windows and I get the screen where the Hello usually open the IR camera to logged me in, I get a message saying preparing, the eye doesnt not move as it did before, I dont see any activity (led blinking) at the camera and finally get a message that it couldnt activate the camera and to use the pin to sign in. Around the same time I also started having problem with the Windows 10 Camera app. When I was trying to use it, I was getting either of the following errors: Cant start the camera 0xA00F429F<WindowsShowFailed> (0x80070002) Close other applications 0xA00F4288<AllCameraAreReserved> I know the integrated camera is working fine since I can use it with Skype, Zoom or Microsoft Teams.I have tried to reinstall the drivers on both cameras, no luck. I have tried from advanced options to reset the Camera app, no luck. I have checked the Camera access and everything seems to be normal and active. I even deactivate it and reactivate it with no luck. I found an entry in a board about a registry entry that seems to have fixed the camera app. It is under: \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Foundation\Platform and the key is: EnableFrameServerMode I also created the same key under: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform Since the creation of both keys the camera application seems to be working. Mind you that some times it just died when I start it but next time it works ok. But I still have the same problem with the Hello and IR camera not working. I have checked for a restore point but I dont have any. I also dont have the option of rolling a version back for Windows. I am currently running under 20H2 and I know that 21H1 is available. Anybody know if there is anything under 21H1 that may help with Windows Hello and the used if IR Camera? I have the Hello finger print reader enable to login and it works fine. So part of the Windows Hello is working. Before trying to start playing with my windows configuration I would like to know if there is a way that I can test the IR Camera. There are sites where I can test the standard integrated camera but I havent found anything where I could test the IR camera. I would like to confirm that the IR works before starting to modify and troubleshoot windows hello. Thank you, Luc Details for Windows version and system.

Can other programs then Windows Hello access an external IR Camera?

I got two web cameras, one normal and another which has an IR camera build in for my Windows Hello sign in function. I can access my normal camera in various applications but I just don't see any app or other way to open up a viewfinder for the IR Camera except when you set it in Windows Hello.

I have put tape over every web camera (except the IR one) but I'm uncertain if it even is possible to spy on me through that IR camera? Anyone who knows a way to spy on me through it? Or does Windows somehow lock it for 3rd party apps after being connected to the Windows Hello login method?

I want to be able to just login without having to take away and reinstall the tape every time i login. It kind of defeats the purpose of having this ease of use login method to begin with.

Here is an similar camera to the one that I got right now:

IR CAMERA DOESN'T TURN ON FOR WIN HELLO

I have the Lenovo yoga s740 IIL and there is problem with the IR Camera. The IR Camera doesn't switch on automictically when camera is disabled. According to Microsoft the camera should switch on even if it is disabled but this is not he case.

I get the white light on top showing that my camera is on (when camera is disabled ) during windows hello but the IR camera doesn't switch on so every time I have to enable the camera using hotkey only for windows hello. This is a big inconvenience and I
don't like keeping my camera enabled and I am thereby now using normal password to unlock the laptop.

Is there any solution to this. Is anyone else facing the same problem with Lenovo laptops

with IR camera for windows hello ?

 

Can Windows Hello face authentication support 2 IR Cameras

We have a laptop that has an IR Camera with Windows Hello face authentication setup and working, but when the user docks their laptop usually has the lid closed so can't use the built in laptop IR camera. We setup and external IR camera to try and resolve
this, but it doesn't work the laptop appears to be able to only use 1 IR camera for Windows Hello. If we disable the laptop IR camera the external camera works, but then the laptop IR camera doesn't work when they're mobile. Is there anyway that Windows Hello
can you both cameras or somehow disable the laptop IR camera when docked?
