FAQ related to Webcam │ 23
Possible causes: In order to support Windows Hello facial
recognition feature using the external webcam, Dell Peripheral
Manager software may have disabled the internal webcam or
other non-Dell webcams. To use other webcams please check
the feature "Prioritize External Webcam" under "Camera
Control" in DPM application to disable/enable this feature.
• Question: Why is there a countdown and my computer is
locked shortly after that?
Possible causes: Your webcam is equipped with a presence
detection sensor called proximity sensor. If the sensor does
not detect human presence in its field of view for a specified
period of time it can lock the system. This feature is the “Walk
Away Lock”. It can be controlled under “Proximity Detection”
in Dell Peripheral Manager application. If Proximity Detection
feature is enabled, do not cover the lens of the webcam or
else the webcam will not be able to detect human presence.
Certain models of Dell system are equipped with a built-in
proximity sensor. If you have one of those systems, we
recommend to disable this feature under Dell Peripheral
Manager application to avoid conflicting behavior.

Manager application on my system. E.g., ARM-based
