# Why built-in cameras work better than external ones? 

If you're getting ready for an interview or a proctored assessment, you'll need a working camera. You can use either the camera that comes built into your laptop or an external webcam. But from our experience, **built-in cameras usually work better** and cause fewer issues.

This guide explains why built-in cameras work better, and what to do if you're using an external webcam.

## ✅ Why Built-in Cameras Are Better?

| **What Matters**               | **Built-in Camera**                   | **External Camera**                       |
| ------------------------------ | ------------------------------------- | ----------------------------------------- |
| **Easy to detect**             | Yes, system picks it up automatically | Sometimes needs manual setup              |
| **Stable connection**          | Fewer chances of disconnection        | May stop working if USB is loose          |
| **Less setup required**        | Just open the browser and go          | May need to choose camera from settings   |
| **More secure for test rules** | Fixed in place                        | Can be moved around, may trigger warnings |

## ❌ Common Issues with External Cameras

| **Problem**               | **Why It Happens**                                | **What You Can Try**                              |
| ------------------------- | ------------------------------------------------- | ------------------------------------------------- |
| Camera not found          | Not plugged in properly or not allowed by browser | Reconnect the camera and restart your browser     |
| Black screen              | Permissions not given to use the camera           | Go to browser settings and allow camera access    |
| Video is blurry or slow   | Low-quality camera or old drivers                 | Try using your built-in camera instead            |
| Camera turns off mid-test | USB gets loose or power drops                     | Use a different port or switch to built-in camera |

## 🔍 How to Check Your Camera Before Starting

You can use this system check before your test or interview. It will check your camera.

To avoid any issues:

1. Make sure **only one camera** is connected.
2. If you have both a built-in and external camera, the system may ask you to choose one.
3. **Pick the built-in one** (it may show as “Integrated Camera” or “Laptop Camera”).

> If your camera isn’t working, don’t start the test yet - **try fixing it first.**

## 📌 When to Use an External Camera

You can use an external camera if:

* Your laptop camera is broken or blocked
* You need better video quality
* You're using a desktop that doesn’t have a built-in camera

Just make sure it’s connected properly and selected in your browser settings.
