Thanks for updating us on the results of the troubleshooting steps that you have completed. Since the built-in webcam is still not working correctly and the same error code 0xA00F4244 (0xC00DABED) is still appearing, we suggest that we check the camera privacy
settings to see if the camera access is turned on. Kindly follow the steps below to check the camera privacy settings:

• Press the Windows key + I to open the Settings app.
• Near the top of the Settings app window is the search box, kindly type the word "webcam" or "camera".
• From the list of results choose Camera privacy settings.
• Make sure that "Let apps use my camera" toggle is set to On.

We look forward to your response once you complete the steps.

IP camera issue with wireless Access Point

well I connected the second router as you said, indeed it stayed on the same subnet, but wouldn't give ip address to the camera, not in router or in AP mode.
However, I managed to solve the problem even with 2 subnets.
On the primary router, I port forwaded port 80 to the ip address of the secondary router.
On the secondary router, I port forwaded port 80 to the ip address of the ip camera.

Now I can access the ip camera from the mobile app AND from any pc/browser externally.

solved, thanks for the suggestions
