Read this blog to know All about ESP32 Camera Module in detail.

Hardware required

• ESP32-CAM Module: This compact board features a built-in camera and Wi-Fi capabilities.
• FTDI Adapter: For programming the ESP32-CAM, you'll need an FTDI adapter or a similar USB-to-Serial converter.
• Jumper Wires: For connecting the ESP32-CAM to the FTDI adapter.
• Power Supply: A stable 5V power source.
• MicroSD Card: For storing images and video recordings (optional but recommended).
• Breadboard and Wires: For prototyping and connections.

Steps to Making Security Camera Using ESP32-CAM:

Step 1: Setting Up the Hardware

1. Connect the ESP32-CAM to the FTDI Adapter:

• TX on FTDI to U0R on ESP32-CAM.
• RX on FTDI to U0T on ESP32-CAM.
• GND on FTDI to GND on ESP32-CAM.
• 5V on FTDI to 5V on ESP32-CAM.
• IO0 on ESP32-CAM to GND (this sets the module to programming mode).

2. Insert the MicroSD Card (if using): Make sure it's formatted to FAT32.
3. Power Up: Connect the FTDI adapter to your computer via USB.

Step 2: Installing the Necessary Software

1. Install Arduino IDE: Download and install the Arduino IDE from the official website.
2. Add ESP32 Board Support:

• Open the Arduino IDE and go to File > Preferences.
• In the Additional Board Manager URLs field, enter https://dl.espressif.com/dl/package_esp32_index.json.
• Go to Tools > Board > Boards Manager, search for ESP32, and install the package.

3. Select the ESP32-CAM Board:

• Go to Tools > Board and select AI Thinker ESP32-CAM.

4. Install the Required Libraries:

• Open Sketch > Include Library > Manage Libraries.
• Search for and install the ESP32 and ESP32 Camera libraries.

Step 3: Uploading the Code

1. Download Sample Code: You can use the sample code provided by the ESP32 library or modify it according to your needs. Here’s a basic example for streaming video:

#include "esp_camera.h"
#include 

// Replace with your network credentials
const char* ssid = "YOUR_SSID";
const char* password = "YOUR_PASSWORD";

// Replace with your network credentials
const char* serverName = "http://your-server-url/upload";

// Camera configuration
camera_config_t config;
void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("Connected to WiFi");

  config.ledc_channel = LEDC_CHANNEL_0;
  config.ledc_timer = LEDC_TIMER_0;
  config.pin_d0 = 5;
  config.pin_d1 = 18;
  config.pin_d2 = 19;
  config.pin_d3 = 21;
  config.pin_d4 = 36;
  config.pin_d5 = 39;
  config.pin_d6 = 34;
  config.pin_d7 = 35;
  config.pin_xclk = 0;
  config.pin_pclk = 22;
  config.pin_vsync = 25;
  config.pin_href = 23;
  config.pin_sda = 26;
  config.pin_scl = 27;
  config.pin_pwdn = 32;
  config.pin_reset = -1;
  config.xclk_freq_hz = 20000000;
  config.pixel_format = PIXFORMAT_JPEG;

  if (psramFound()) {
    config.frame_size = FRAMESIZE_UXGA;
    config.jpeg_quality = 12;
    config.fb_count = 2;
  } else {
    config.frame_size = FRAMESIZE_XGA;
    config.jpeg_quality = 12;
    config.fb_count = 1;
  }

  esp_err_t err = esp_camera_init(&config);
  if (err != ESP_OK) {
    Serial.printf("Camera init failed with error 0x%x", err);
    return;
  }
}

void loop() {
  camera_fb_t *fb = esp_camera_fb_get();
  if (!fb) {
    Serial.println("Camera capture failed");
    return;
  }
  
  // Upload to server or save to SD card
  
  esp_camera_fb_return(fb);
  delay(10000); // Wait 10 seconds before capturing next frame
}

2. Upload the Code: Within the Arduino IDE, click the upload button. Once done, disconnect the IO0 pin from GND and press the reset button on the ESP32-CAM.

Step 4: Accessing the Camera Stream

1. Find Your IP Address: Open the Serial Monitor in Arduino IDE to find the IP address assigned to your ESP32-CAM.
2. View the Stream: Open a web browser and enter the IP address. You should see the live video stream from your ESP32-CAM.

Step 5: Advanced Features

1. Motion Detection: Implement motion detection by comparing consecutive frames to detect changes.
2. Email Alerts: Configure your ESP32-CAM to send email alerts when motion is detected.
3. Cloud Storage: Set up cloud storage solutions to automatically save images or video recordings.
