# Webcam Troubleshooting

The ability to record videos is a critical part of the **Big Interview Medical** mock interview experience. To ensure a seamless session, we recommend testing your hardware well before your assignments are due. If your webcam is not connecting, please follow these troubleshooting steps.
### **1. Preliminary Checks**
* **Restart your computer:** This remains the most effective first step, resolving the majority of hardware connection issues.
* **Close competing apps:** Ensure no other applications (e.g., Zoom, Microsoft Teams, FaceTime) or other browser tabs are currently using your camera. Webcams generally only allow one connection at a time.
* **Check physical connections:** If using an external webcam, ensure it is securely plugged into a working USB port. If you have multiple cameras, verify that the correct device (internal vs. external) is selected in your browser settings.
### **2. Browser Settings & Compatibility**
* **Use a supported browser:** We recommend using the most recent versions of **Google Chrome** or **Mozilla Firefox**.
* **Update your browser:** Ensure your browser is up to date by checking **Settings > About Chrome** (or Firefox) to trigger any pending updates.
* **Permissions & Pop-ups:** When prompted, select **"Allow"** on the webcam permission pop-up. If you previously denied access, click the **Camera or Lock icon** in your address bar to reset permissions, then refresh the page.
* **Try Incognito Mode:** Opening an incognito or private window can help determine if a browser extension is interfering with your camera.
### **3. Operating System Privacy Settings**
Modern operating systems require you to grant the browser permission to access your hardware at the system level.
#### **For Windows Users:**
1. Go to **Start > Settings > Privacy & Security**.
2. Select **Camera** under "App permissions."
3. Ensure "Camera access" is toggled **On**.
4. Scroll down to "Let desktop apps access your camera" and ensure your browser (Chrome or Firefox) is allowed.
#### **For macOS Users:**
1. Go to the **Apple Menu > System Settings (or System Preferences) > Privacy & Security**.
2. Select **Camera** from the list.
3. Ensure the toggle or checkbox next to your browser is enabled to allow access.
4. Repeat these steps for the **Microphone** if you are experiencing audio issues.
### **4. Advanced Troubleshooting**
* **Update Drivers (Windows):** Right-click the **Start** button and select **Device Manager**. Find your camera under "Cameras," right-click it, and select **Update driver**.
* **Clear Cache and Cookies:** This can resolve "stuck" data or expired session permissions within your browser.
* **Check Antivirus Settings:** Some security software includes "Webcam Protection" that may block browser access by default.
