EloquentSurveillance for Arduino

EloquentSurveillance is an Arduino library that makes it a breeze to integrate pure video motion detection (whitout pir!) in your project.

It comes with batteries included:

• easy camera configuration
• HTTP streaming server
• HTTP file browser
• Motion detection
• SPIFFS / SD file storage
• Telegram notifications

Every feature have been carefully designed to be as easy to use as possible, often requiring only 2-3 lines of code.

A complete motion dashboard

Motion detection is only the beginning. EloquentSurveillance comes with a fully-featured admin dashboard to manage your motion events.

It stores your motion pictures and delivers notifications to many channels:

• Telegram
• Email
• Web push
• Slack
• Webhook

Go check it out at the Eloquent Motion website.

Motion Detection Example

The following sketch performs basic motion detection. You can then perform the action you prefer based on the detection result.

#define VERBOSE
#include "EloquentSurveillance.h"


EloquentSurveillance::Motion motion;


/**
 *
 */
void setup() {
    Serial.begin(115200);
    delay(3000);
    debug("INFO", "Init");

    // configure camera
    camera.m5wide();
    camera.qvga();
    camera.highQuality();

    // configure motion detection
    //  > setMinChanges accepts a number from 0 to 1 (percent) or an integer
    //    At least the given number of pixels must change from one frame to the next
    //    to trigger the motion
    motion.setMinChanges(0.1);
    //  > setMinPixelDiff accepts an integer
    //    Each pixel value must differ at least of the given amount from one frame to the next
    //    to trigger the motion
    motion.setMinPixelDiff(10);
    //  > setMinSizeDiff accepts a number from 0 to 1 (percent) or an integer
    //    The filesize of one frame from the next must change of at least the given amount
    //    to check for motion
    motion.setMinSizeDiff(0.05);

    while (!camera.begin())
        debug("ERROR", camera.getErrorMessage());
    
    debug("SUCCESS", "Camera is initalized");
}

/**
 *
 */
void loop() {
    if (!camera.capture()) {
        debug("ERROR", camera.getErrorMessage());
        return;
    }

    if (motion.update()) {
        debug("INFO", String("Motion detected in ") + motion.getExecutionTimeInMicros() + " us");
    }
}

Motion Detection to Telegram Example

The following sketch sends a notification to Telegram when motion is detected.

#define VERBOSE

#include "EloquentSurveillance.h"
#include "TelegramChat.h"

#define WIFI_SSID "Abc"
#define WIFI_PASS "12345678"
#define BOT_TOKEN "XXXXXXXXXX:yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy"
#define CHAT_ID 1234567890

EloquentSurveillance::Motion motion;
EloquentSurveillance::TelegramChat chat(BOT_TOKEN, CHAT_ID);


/**
 *
 */
void setup() {
    Serial.begin(115200);
    delay(3000);
    debug("INFO", "Init");

    // configure camera
    camera.m5wide();
    camera.vga();
    camera.highQuality();

    // configure motion detection
    motion.setMinChanges(0.05);
    motion.setMinPixelDiff(7);
    motion.setMinSizeDiff(100);

    while (!camera.begin())
        debug("ERROR", camera.getErrorMessage());

    while (!connectToWiFi(WIFI_SSID, WIFI_PASS))
        debug("ERROR", "Cannot connect to WiFi");

    debug("SUCCESS", "Camera OK, WiFi connected");
}

/**
 *
 */
void loop() {
    if (!camera.capture()) {
        debug("ERROR", camera.getErrorMessage());
        return;
    }

    if (motion.update()) {
        debug("INFO", String("Motion detected in ") + motion.getExecutionTimeInMicros() + " us");

        bool messageResponse = chat.sendMessage("Motion");
        debug("TELEGRAM MSG", messageResponse ? "OK" : "ERR");

        bool photoResponse = chat.sendPhoto();
        debug("TELEGRAM PHOTO", photoResponse ? "OK" : "ERR");
    }
}
