ESP32-S3 CAM Live Streaming on Your Phone From Anywher

The ESP32-S3 CAM is a small and affordable camera board that can stream live video over Wi-Fi.

In this project, we'll make the camera accessible from our phone and use ngrok to access it remotely.

What You'll Need

• ESP32-S3 CAM

• USB cable

• Wi-Fi connection

• Computer

• ngrok account

Step 1: Connect the ESP32-S3 CAM to Wi-Fi

First, upload the camera streaming code to your ESP32-S3 CAM.

Add your Wi-Fi name and password:

const char* ssid = "YOUR_WIFI_NAME";
const char* password = "YOUR_WIFI_PASSWORD";

Upload the code and open the Serial Monitor.

Once connected, the ESP32-S3 CAM will display its local IP address.

For example:

http://192.168.1.100

Open this address in your browser to access the live camera stream.

Step 2: Test the Local Camera Stream

Make sure your phone or computer is connected to the same Wi-Fi network as the ESP32-S3 CAM.

Open the camera's IP address and start the live stream.

Your camera is now working locally! 📹

However, there is one limitation.

The camera cannot be accessed when you leave the Wi-Fi network.

Step 3: Use ngrok

1. Create an ngrok Account

Go to ngrok and create a free account.

2. Install ngrok

If you're using a Mac, open Terminal and run:

brew install ngrok

You can also download ngrok directly from the official website.

3. Add Your Authtoken

Copy your authtoken from your ngrok dashboard and run:

ngrok config add-authtoken YOUR_AUTHTOKEN

4. Start the Camera Tunnel

Make sure your ESP32-S3 CAM is running and accessible on your local network.

Then run:

ngrok http YOUR_ESP32_IP:80

For example:

ngrok http 192.168.1.100:80

ngrok will generate a public URL.

Open that URL on your phone, and you can access your ESP32-S3 CAM remotely! 📱📹

ngrok creates a tunnel that allows you to access a local service through the internet.

Open your terminal and start ngrok using the port where your camera stream is available.

Step 4: Open the Camera From Your Phone

Copy the ngrok URL and open it on your phone.

Now try turning off Wi-Fi and switching to mobile data.

Open the ngrok URL again.

If everything is working correctly, you should be able to see your ESP32-S3 CAM live stream remotely! 🎉

Important Security Note

Be careful when making a camera accessible through the internet.

Do not use a publicly accessible stream as a real security system without proper authentication and security.
