Overview

ScreenStop runs as three components on each protected workstation:

Component	Role
ScreenStopMain	Background daemon — camera detection, YOLO + InsightFace
ScreenStopMenu	Menu bar app — controls daemon, syncs config from dashboard
ScreenStopGUI	Control Center — local settings, face enrollment

All three are installed together via the .pkg (macOS) or .exe (Windows) installer.

How it works

1. ScreenStopMenu launches on login and starts ScreenStopMain
2. The daemon captures frames from the webcam every ~1.4 seconds
3. YOLO detects phones and persons; InsightFace identifies faces
4. On a threat → screen locks immediately
5. All events are sent to the Dashboard in real time
6. The Dashboard can push config changes back to stations
