- Detect screenshots taken
- Detect tab changes or screen switches
- Detect voice or speaking in the room
- Detect working camera and microphone status (e.g., muted)
- Detect more than one face
- Detect camera obstruction with objects
- Detect low room light
- Detect eye and head movements

Ideal Skills and Experience:
- Experience in developing monitoring applications
- Proficiency in cross-platform software development
- Knowledge of system processes and resource monitoring
- Familiarity with real-time detection algorithms
- Strong programming skills in relevant languages (e.g., C++, Python)

Please provide a portfolio showcasing similar projects and ensure the app is lightweight and efficient.
