1. INTRODUCTION

The Internet of Things (IoT) is an important topic in technology industry, policy, and

engineering circles and has become headline news in both the specialty press and the popular

media. This technology is embodied in a wide spectrum of networked products, systems, and

sensors, which take advantage of advancements in computing power, electronics

miniaturization, and network interconnections to offer new capabilities not previously

possible. An abundance of conferences, reports, and news articles discuss and debate the

prospective impact of the “IoT revolution”—from new market opportunities and business

models to concerns about security, privacy, and technical interoperability

This project focuses on exploiting IOT to ensure a better security system in

households. The present doorbell systems follow traditional approach, when a visitor presses

the switch bell that rings inside the house. If someone is present in the house they open the

door and if no one is present in the house the visitor waits for certain time and leaves the

place without any clue. Over the past few years technology has taken over the society.

Technology is vital today and makes everything easier. One such advancement in the field of

doorbell is using “The Automatic doorbell system” (ADBS). Door bells have moved from

historical switches to modern touch pads and now it is more sophisticated with the usage of

sensors and IOT.

In this system, security that combines the functions of smart phone and home network

system. It enables the users to monitor visitors in real-time, remotely via the IoT-based

doorbell installed near the entrance door to a house. This system makes security as further

autonomous by capturing the image automatically and processing the image for facial

matching and uses mail communication to the server to confirm the intruder is known or

unknown. And also make them as a known person by entering the OTP which is sent to the

mail server.

A security system is one of the most researched fields of today. Through this project,

you will develop an electronic device that can detect the human activity and switch on the

doorbell automatically to notify the residents. The system will also be connected to the

internet and can send the data to the cloud spontaneously.

2. LITERATURE REVIEW The system, ‘Home Security System for Alone Elderly People’, is a project which was implemented in Thailand. It is in the aging society because the number of elderly population is more than 10 percent and keeps increasing every year, while the household size is decreasing. As a consequence, more elderly people have to live alone. Moreover, there are more than 10 percent of elderly's accidents occurred each year. In 2015, elderly abuses are more than 2 million cases and most of them are in elderly's house. With these reasons, Home Security System for Elderly People Who Live Alone is proposed to facilitate and increase the security level for elderly people. The system is a smart doorbell which allows elderly people to see, hear, and speak to their visitors at the front door via their mobiles to avoid a face-to- face communication. Another research, ‘Real Time Smart Door System for Home Security’, they tried to implement the similar idea for a smart doorbell. According to this system, most of the proposed smart home systems try to bring solutions for security problem, but many of those systems use numerous sensor devices. Video based smart home security systems is an efficient approach with the development of video technology and Raspberry Pi is a strong and reliable embedded system device for the complex and challenging tasks. Using these technologies in the proposed system will bring several advantages in providing safety and security in terms of visualizing and identifying people who visit the home. In the overall proposed system, there will be two different significant techniques to provide home security. The paper, ‘Automatic Safety Home Bell System with Message Enabled Features’, focuses on IOT related automatic doorbell systems which are designed to ring the bell automatically when a visitor approaches the door. If the visitor stands for more than a specified time span without the door being opened, an SMS will be sent to a registered mobile number of the house member and the response of the house member (i.e. in the form of an SMS) will be displayed on an LCD screen placed beside the door so that the visitor can read the SMS and act accordingly. This system was intended to service old age people and also to identify the unauthorized persons, if any.

WiFi Module: ESP8266 WiFi module is generally used to establish the wireless communication between the devices. But this module is not capable of 5-3V logic shifting and will require an external logic level converter.
PIR Sensor: This electronic sensor is used to detect the movements of humans within a certain range (5 – 12 m). It actually comprises of pyro electric sensors that detect the levels of infrared radiations.
Camera Module: A camera module will be mounted onto the system to monitor the human activities outside the house
Piezo Buzzer: A piezo buzzer is a loudspeaker that uses the piezoelectric effect to generate sound. It has both a piezo disc and an oscillator inside. Whenever the buzzer is powered, the oscillator generates a frequency around 2-4 kHz and the piezo element vibrates accordingly to produce the sound.
Servo Motor: Servo motor is a rotary actuator or linear actuator that is capable of carrying out precise control of angular or linear position, velocity and acceleration. It uses a suitable motor coupled to a sensor for position feedback. 5. BLOCK DIAGRAM Fig 1: Block Diagram for the System

Block diagram description Calling bell switch which is interfaced to raspberry pi through GPIO pins, which triggers the camera when the switch gets pressed that camera is interfaced through USB. Using python OpenCV input image will be processed and authorize the user, for authorized person an alert mail will be sent along with OTP using SMTP. Now the user has to enter the OTP through keyboard which is interfaced in the USB port of the Raspberry pi.

A. Connecting bell to Arduino Board

Connect the short leg of the LED to this same ground rail on the breadboard then connect the long leg to a row on the breadboard.
Connect the 220-ohm resistor from pin 13 to the same row that you have the long leg of the LED attached.
Place the pushbutton on the breadboard. Most buttons will straddle the center trench on the breadboard.
Connect one side of the 10k resistor from the ground rail on the breadboard to the other side to the pushbutton – on the same side that pin 2 connects.
Plug the Arduino board into your computer with a USB cable.
Open the Arduino IDE.
Open the sketch for this section.
Click the Verify button on the top left. It should turn orange and then back to blue.
Click the Upload button. It will also turn orange and then blue once the sketch has finished uploading to your Arduino board.

11. CONCLUSION The project named "Smart IOT Doorbell Surveillance" has been designed with the domain as Internet of Things. The basic concepts and working of IOT has been displayed in the running of the project. The project uses mainly an Arduino Board and OOPS programming concept. Since, today, in a technologically enhancing environment, security issues is of utmost concern, this project shows how technology can be used to enhance the security features of people's homes. A doorbell is constructed which has the feature to send a notification to the owner when somebody is at the door, with an attached picture of the person. It uses materials such as an Arduino Board, an Ethernet Shield (to send notifications across services), a doorbell, resistors and a web camera. This project enables users to stay connected to their homes and ensure safety, even when they're travelling.
