ESP 32 Camera Streaming Video Over WiFi |Getting Started With ESP 32 CAM Board

The ESP32-CAM is a very small camera module with the ESP32-S chip that costs approximately $10. Besides the OV2640 camera, and several GPIOs to connect peripherals, it also features a microSD card slot that can be useful to store images taken with the camera or to store files to serve to clients.

In your Arduino IDE, go to File > Examples > ESP32 > Camera and open the CameraWebServer example.

OR Download the code from here :

The ESP32-CAM doesn’t have a USB connector, so you need to use FTDI to upload code through the U0R and U0T pins (serial pins) in ESP32 CAM Board.

Please refer the schematics below

Before uploading the code, you need to input your wifi credentials in the following part of code:

const char* ssid = "REPLACE_WITH_YOUR_SSID";

const char* password = "REPLACE_WITH_YOUR_PASSWORD";

and make sure you select the right camera module.

As here we’re using the AI-THINKER Model so select the following So, comment all the other models and uncomment this one:

#define CAMERA_MODEL_AI_THINKER

follow these steps to upload the code : Go to Tools > Board and select ESP32 Wrover ModuleGo to Tools > Port and select the COM port the ESP32 is connected toIn Tools > Partition Scheme, select “Huge APP (3MB No OTA)“Then, click the upload button to upload the code.

Remove the jumper connected between GPIO0 & GND then,

Open the Serial Monitor with the baud rate : 115200. Press the ESP32-CAM on-board Reset button and wait for the IP to appear and wait for few seconds and then hit reset again.

Open your browser and make sure your PC is connected to same network as ESP32 CAM and then type the IP and click on stream button and you’ll get similar video stream.
