# Camera & Mic Set Up

Your camera and microphone performance depends on your browser’s compatibility with **WebRTC**, the modern standard for real-time communication. To ensure a smooth recording experience, please follow the steps below to configure your hardware and permissions.
### Granting Browser Permissions
When you first enter the mock interview practice area, your browser will request permission to access your webcam and microphone.
**Google Chrome & Firefox:**
1. Look for a pop-up alert near the top-left corner of your browser window.
2. Click **Allow**.
3. If you do not see the prompt or accidentally blocked it, click the **Lock icon** or the **Camera icon** located on the left side of the address bar.
4. Toggle the Camera and Microphone switches to **On** or select **Allow** from the dropdown menu.
5. **Refresh the page** to apply the changes.
### System Privacy Settings
Even if browser permissions are granted, your operating system may block camera access at a global level.
**macOS:**
1. Open **System Settings** (or System Preferences) > **Privacy & Security**.
2. Select **Camera** from the list and ensure your browser (Chrome or Firefox) is toggled **On**.
3. Repeat this process for the **Microphone** section.
**Windows:**
1. Open **Settings** > **Privacy & Security** (or Privacy).
2. Under **App permissions**, click on **Camera**. Ensure "Camera access" is **On** and that your browser has permission to access it.
3. Repeat these steps for **Microphone** settings.
### Device Selection and Connection
If your camera or audio device is not appearing, verify your hardware connections:
* **External Devices:** Ensure USB webcams or headsets are securely plugged in.
* **Selection:** Within the Big Interview hardware settings, confirm that the correct device is selected from the dropdown menu (e.g., "Integrated Camera" vs. "External USB Webcam").
* **Conflicts:** Close other applications that may be using your camera or mic, such as Zoom, Teams, or FaceTime, as these can prevent the browser from accessing the hardware.
### Optimizing Your Recording Environment
To ensure the best results for your practice sessions, follow these quality standards:
* **Lighting:** Position your primary light source in front of you rather than behind you. Avoid sitting directly in front of a bright window, which can create a silhouette effect.
* **Audio:** Record in a quiet space. Use a dedicated headset or external microphone if possible to minimize background noise and echo.
* **Framing:** Position your camera at eye level. Sit at a distance where your head and the top of your shoulders are visible, maintaining a professional "headshot" composition.
