In this tutorial, you’ll learn how to use an ESP32 camera module that includes built-in USB connectivity for uploading code and powering the device. This project is perfect for those looking to stream video wirelessly from their ESP32-CAM module to a smartphone or PC browser. You will also learn how to enable face detection and use a convenient web interface for camera control.

This version of the ESP32 camera module comes with everything integrated — no need for external FTDI adapters or UART connections. This makes it easier to deploy and ideal for rapid development.

The source code, necessary libraries, and documentation are available below this article.

📦 What’s Special About This ESP32-CAM?

Unlike earlier versions that required separate serial connections to upload code, this ESP32-CAM board features a built-in micro USB port for both uploading code and powering the module. This drastically simplifies setup and is especially useful for beginners or quick prototyping.

The board can be purchased from platforms like AliExpress, Amazon, and others as a ready-to-use module.

🛠️ Key Features Covered

• Direct upload via USB (no separate UART required)

• Video streaming via browser on mobile or PC

• Option to enable face detection

• Step-by-step walkthrough in Arduino IDE

The video tutorial walks you through the entire process from recognizing the USB port to deploying the code and viewing live stream output from your browser.

📱 Streaming and Face Detection

Once the code is uploaded, you can connect your mobile phone or PC to the same Wi-Fi network and view the camera stream by entering the IP address shown in the serial monitor. The interface allows:

• Real-time video streaming

• Face detection and face recognition options

• Camera settings (resolution, brightness, etc.)

All features are accessible through a clean web dashboard provided by the default ESP32-CAM firmware.
