ESP32-CAM Made Easy

This book is for you if

You are a beginner and…

you want to start learning from the basics. You are not comfortable with complex, convoluted code that makes you wonder which line is doing what
you like to learn by doing. You want to see the code in action and understand how it works
you want features out of the box: SD storage, cloud storage, Telegram notifications, motion detection…

You are an expert and…

you want to kickstart your projects by abstracting away repetitive code
you want to access advanced features like AI, multithreading, MQTT…

What's inside

Chapter	What you'll build
Quickstart	Configure the image sensor and take your first picture
Live streaming	View the camera feed in real time from any web browser
Save pictures to SD	Save pictures on the SD card, with timestamps and nested folders
Save pictures in cloud	Save pictures in the cloud, without setting up your own server
Telegram notifications	Send text and images to your Telegram bot without complex setups
Email notifications	Send images to your email inbox without complex setups
Motion detection	Detect moving objects from the camera frames, without an external PIR sensor
Motion detection streaming	Debug the motion detection algorithm in real time using a web browser
Face detection	Find faces in pictures, including landmarks for eyes, nose and mouth
Face detection streaming	Debug the face detection algorithm in real time using a web browser
Face recognition	Enroll and recognize faces for smart access control
Object detection	Train a neural network to recognize any kind of object in real time
Camera web server	The iconic CameraWebServer example with a fresh look

Example: how to take a picture

#include <espkit.h>
#include <espkit/camera.h>

void setup() {
    Serial.begin(115200);
    delay(3000);

    camera.pinout.aithinker();
    camera.brownout.disable();
    camera.resolution.vga();
    camera.quality.high();

    while (!camera.begin())
        Serial.println(camera.exception.toString());

    Serial.println("Camera OK");
}

void loop() {
    if (!camera.capture()) {
        Serial.println(camera.exception.toString());
        return;
    }

    Serial.printf("Captured %d bytes\n", camera.getSizeInBytes());
    delay(1000);
}

Example: motion detection

#include <espkit.h>
#include <espkit/camera.h>
#include <espkit/motion.h>

void setup() {
    Serial.begin(115200);
    delay(3000);

    camera.pinout.aithinker();
    camera.brownout.disable();
    camera.resolution.vga();
    camera.quality.high();

    motion.config.stride(2);
    motion.config.threshold(15);

    while (!camera.begin())
        Serial.println(camera.exception.toString());
}

void loop() {
    if (!camera.capture())
        return;

    if (!motion.update(camera.frame))
        return;

    if (motion.detected())
        Serial.println("Motion detected!");
}
