1. Types of In-Car Cameras

🔹 1. Driver Monitoring System (DMS) Cameras

📍 Purpose:

• Monitors driver’s face & eyes for drowsiness, distraction, or inattention.

• Helps in Driver Fatigue Detection & alerts the driver.

• Required for Euro NCAP & regulations like GSR 2024 in the EU.

📍 Common Features:

✅ Eye tracking

✅ Head position detection

✅ Yawning detection

✅ Adaptive cruise control integration

📌 Example: Used in Tesla, BMW, and Mercedes for driver attention monitoring.

⸻

🔹 2. Cabin Surveillance Cameras

📍 Purpose:

• Monitors passengers & activities inside the vehicle.

• Used for ride-sharing safety, security, and infotainment.

📍 Common Features:

✅ Passenger presence detection

✅ Child left-behind alert (hot car death prevention)

✅ Gesture recognition for infotainment control

📌 Example: Mercedes-Benz MBUX interior assistant uses cabin cameras for gesture control.

🔹 3. Surround-View & Parking Cameras

📍 Purpose:

• Provides 360-degree visibility for parking & maneuvering.

• Used in Autonomous Parking Systems.

📍 Common Features:

✅ 360-degree bird’s-eye view

✅ Automatic parking assist

✅ Obstacle detection

📌 Example: BMW’s 360-degree camera system for automated parking.

🔹 4. Dash Cameras (Dashcams)

📍 Purpose:

• Records road events for security & accident evidence.

• Can be front-facing, rear-facing, or dual-channel (inside + outside).

📍 Common Features:

✅ Continuous loop recording

✅ Night vision

✅ GPS tracking

📌 Example: Tesla Sentry Mode records activities around the parked vehicle.

🔹 5. Rearview & Side Mirror Cameras

📍 Purpose:

• Replaces traditional mirrors with camera-based digital mirrors.

• Reduces blind spots & improves aerodynamics.

📍 Common Features:

✅ Wide-angle vision

✅ Night mode

✅ Anti-glare display

📌 Example: Audi e-Tron uses digital side mirrors for better aerodynamics.
