doorbell camera no wifi needed

Nowadays, Security scheme is one of the most researched W. C. Fields and with increasing security system threats, companies are launching new overbold security department products to combat these threats. IoT is an added vantage in that field which can automatically trigger an event, same calling the police, fire brigade OR your neighbour, just in case of any emergency. We previously reinforced many security systems like Raspberry Pi Visitor monitoring system, video surveillance camera, wireless doorbell, IoT supported Door Security Alarm etc. Today we will use ESP32 and photographic camera to work up a Smart Wi-Fi door bell.

In another tutorial, we have learned most ESP32-CAM and how to use it for telecasting flowing, now we leave make a Smart Wi-Fi Television Doorbell using ESP32-Cam River. This Voguish buzzer can well represent supercharged by an AC socket and whenever someone at the door presses the doorbell clitoris, it will shimmer a specific birdcall on your phone and sends a school tex subject matter with a link of video recording streaming Sri Frederick Handley Page where you privy get word the person at the door from anywhere in world.

Components Required

• ESP32-CAM
• FTDI Programing Board
• 220V AC to 5V DC Converter
• Buzzer
• Push Push button
• LED (2)

Circuit Plot

Circuit diagram for this Smart Wi-Fi Doorbell is selfsame retarded, just now connect two LEDs, a button and a buzzer to ESP32 GPIO pins. A buzzer is used to make a uninjured whenever the clitoris is pressed. United LED is used to indicate the power position, and the other LED is used to indicate the network status. Net LED will be in a high commonwealth if ESP is adjacent to a network other, it will blink.

This is how the Wi-Fi video doorbell setup will look in 3D printed casing:

IFTTT Frame-up for Badger State-Fi Doorbell

IFTTT is a free web-based service that allows users to create irons of four-needled conditional statements, named "recipes", which are triggered supported changes to other web services such As Gmail, Facebook, Instagram, and Pinterest.IFTTT is an abbreviation of "If This So That".

In this send off, IFTTT is used to send an Email whenever the temperature or humidity goes on the far side a predefined limit. We previously used IFTTT in many IoT based projects to send emails or SMS connected particular events ilk on excessive electricity consumption, on high pulse rate, on intruder entry, etc.

First login to IFTTT with your credentials orSign if you don't have an account thereon.

Now hunting for 'Webhooks' and click happening the Webhooks in Services section.

Now, in the Webhooks windowpane, clink on 'Documentation' in the upper right corner to get the private key.

Copy this identify. IT will glucinium used in the program.

Afterward getting the private key, now we will create an applet using Webhooks and Email services. To make up an applet click on your visibility and so click on ' Create. '

 Immediately in the succeeding window, click on the 'This' icon.

Now search for Webhooks in the search section and click on 'Webhooks. '

Now choose ' Pick up a Web Request'  trigger and in the next window, enter the event epithet asbutton_pressed and so click along create a trigger.

Now to complete the applet, click on 'That' to create a response for the button_pressed consequence.

Here we will encounter a specific song on the phone when the IoT buzzer button is ironed. For that search for 'Android device' in the search section.

Now in Android Device, pick out ' Play a specific song' trigger.

Now enter the song title that you want to play when the doorbell button is pressed. In my case, I'm playing a birdcall named '123' from my Google run music. You can as wel use Spotify or other euphony apps.

After that, click on ' Produce action' and past 'Finish' to complete the process.

Now create another applet to send a content with the webpage link to the phone when the doorbell push is pressed.

Thus to make this applet choose ' Webhooks' in 'this' section and in 'that' section select 'Android SMS.'

Now it will ask to enter the call telephone number and message body. For this Wisconsin-Fi doorbell propose, we are sending a message with the Webserver link and then that you potty see the loaded video streaming directly.

Code Explanation

Complete code along with the television for this Wi-Fi doorbell camera is given at the end of this document. It send away also be downloaded from here. Below we are explaining some important parts of the write in code.

First, include each the required library files for this code.

#include "esp_camera.h" #include <WiFi.h>

Then enter the Wi-Fi credentials.

const char* ssid = "Wi-Fi Discover"; const blacken* countersign = "Wi-Fi Password";

After that, enter the IFTTT hostname and private key that you copied from the IFTTT website.

const scorch *host = "Almighty.ifttt.com"; const char *privateKey = "Your Private Key";

Delimitate completely the pins that you are using in this project. I'm using the GPIO 2, 14 and 15 pins to connect the push button, LED and buzzer.

const int buttonPin = 2; const int led1 = 14; const int doorbell = 15;

Inside the void apparatus loop, define the button pin as input and LED and buzzer pins American Samoa output.

vacancy apparatus() {   pinMode(buttonPin, INPUT);   pinMode(led1, End product);   pinMode(buzzer, Production);

It will try to connect to Wi-Fi using the conferred credentials, and when related to a network LED state will change from low to high.

WiFi.begin(ssid, password);   int led = LOW;    while (WiFi.status() != WL_CONNECTED) {     delay(500);     Serial.print(".");     digitalWrite(led1, LED);     led = !led;   }   Serial.println("");   Serial.println("WiFi connected");   digitalWrite(led1, Piping);

While disconnected from a network ESP32 will re-start until it connects to a network.

patc (WLAN.status() == WL_DISCONNECTED) {     ESP.restart();     digitalWrite(led1, LOW);     Consecutive.print("Connection Lost");        

ESP32 will read the release state, and if the button is in the LOW state (pulled high), i.e., a button has been pressed, it sends the consequence and turns on the buzzer for 3 seconds.

int reading = digitalRead(buttonPin); if (buttonState == LOW) {         send_event("button_pressed");         Serial.print("push button pressed");         digitalWrite(bell, Stinky);         delay(3000);           digitalWrite(buzzer, LOW);

3D Written Casing for Smart Wi-Fi Buzzer

Here I designed a 3D printed casing for this radio doorbell camera. For that, I metrical the dimensions of the ESP32 board, Pushbutton, Buzzer and Light-emitting diode victimisation my vernier caliper and the design looked something like this on a lower floor once it was through.

After that, I exported it as an STL file, chopped it settled on printer settings, and lastly printed it. The STL file is available for download from Thingiverse and you can print your own casing using it.

Afterward printing the case, I assembled the circuit into my casing and everything was a nice fit, as you can consider present.

If you want to know more about a 3D printer and how it works you can learn this article on Beginners Guide to Getting Started with 3D Printing process and can likewise check our other projects where we used 3D printed casings like Two-footed Robot, Robotic Arm, etc.

Examination the Smart Badger State-Fi Doorbell

After assembling the circuit, big businessman the Doorbell using an AC socket. Today whenever the IoT buzzer push is ironed the smartphone starts playing a song named '123,' and a message will be received with a data link of a web page as shown downstairs, where the live television feed can be seen.

Absolute encipher and employed video for this Canny Wi-Fi doorbell can Be establish at the end of the document surgery you can download the code from here. If you have some queries regarding this project, leave them in the comment plane section.
