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.
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
- Web push
- Slack
- Webhook
Go check it out at the Eloquent Motion website.
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");
}
}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");
