🎥 Media Devices

The MediaDevices API allows websites to enumerate available cameras, microphones, and speakers, which can be used for fingerprinting.

🔬 How It Works

navigator.mediaDevices.enumerateDevices()
    .then(devices => {
        devices.forEach(device => {
            console.log(device.kind);     // "audioinput", "videoinput", "audiooutput"
            console.log(device.label);    // Device name (if permission granted)
            console.log(device.deviceId); // Unique device identifier
        });
    });

📊 Fingerprinting Data

• Number of devices: How many cameras/mics you have
• Device IDs: Unique identifiers per device
• Device labels: Names like "HD Webcam C920"
• Device types: Input vs output devices

🛡️ Antidetect Handling

Antidetect browsers can spoof the number and types of media devices, or return empty lists to appear as a device without camera/microphone.
