Photo capture on failed unlock
What it does: Silently takes a webcam photo every time someone enters the wrong PIN.
User benefit: Visual proof of who was at your keyboard, not just a log entry.
How it works: The capture is instant and completely invisible to the person at the lock screen.
Good to know: No camera indicator or flash is shown. The capture is discreet.
Limitations: If the webcam encounters a serious error, capture may pause until the next session.
