Abstract - Our system focuses on the all-round security of
the users keeping their comfort levels intact. We will be
using an RFID card and reader for the authorized people
who would scan the card and an OTP would be generated
automatically and sent to the registered number depending
on the RFID number where we would be providing a touch-
screen display to enter the OTP. Users would be asked to
enter the OTP to unlock the door. For unauthorized people
the PIR sensor is used to send the image of the person after
waiting for a stipulated time so that the user gets a fair
chance to do the needful if he is an authorized person. Once
the time is over the camera which is connected to the
microcontroller would send the photo of the unauthorized
person through the application which we would be
developing for the ease of the digitally inclined world. In this
application we would provide two administrators per lock
who would be having a notification in the application and
would get a pop-up which would ask the admin whether to
unlock the door for that person or not. Once the decision is
made to unlock one more pop-up would come up to confirm
their decision and if it's again granted then the door would
be unlocked else the door remains locked. This would not
just level up the security of the place but also the level of
comfort for the users.

1. INTRODUCTION
The Internet of things (IoT) is one of the growing features
in modern technology. IoT enables us to control various
physical devices through the use of software. That means
access to any connected device irrespective of place and
time. As the passage of time, Internet of Things (IoT) has
matured and evolved into a comprehensive system
encompassing wireless networks, internet, embedded
system and with further development AI and ML can also
be integrated in it. In its most practical form, IoT, in the
rapid orchestration of messages across objects in the
Internet, allows objects sharing using remote accessibility
across existing network organization. Practically IoT is
through the use of internet infrastructure to share objects
or packets of data via the internet thus enabling the
remote aspect of IoT. This helps achieve better
productivity, accuracy and economic benefit at the cost of
human involvement.
A Passive Infrared (PIR) sensor works by sensing
variations in the amount of infrared radiation impacting
upon it, which varies depending on the temperature and
surface characteristics of the objects in front of the sensor.
When an object, like an individual, passes ahead of the
background, like a wall, the temperature at that time
within the sensor's field of view will rise from room
temperature due to blood being at a different temperature
than the room and will fall back when the person passes
the field of vision. The change is detected by the sensor
and an output voltage is generated. Each object has a
distinct infrared emission pattern based on the surface
characteristics irrespective of the temperature.
Smart security system using IoT with PIR sensor and
camera module is an interesting idea to involve detection
of sensing of the moving objects. This system can be
integrated along with a lock system consisting of a RFID
system to generate a one-time password that can be used
to control the lock. The security is increased due to
multiple layers of authentication thus increasing the
security. Thus, surveillance systems can also be used as a
security system.
2. LITERATURE REVIEW
Home based IoT automation and Surveillance System using
Internet of Things are some major applications in the
current world. It is used to analyse and collect the
information from the various sensors and actuators and it
then sends the data to the user over a wireless connection.
Security is an imperative issue nowadays as the
opportunity for intrusions is growing. In this paper, the
proposed system is designed on Raspberry Pi 3B. The
Raspberry Pi 3B is interfaced with a door strike to control
the door lock and also a camera is connected to the
Raspberry Pi- 3B Board.
Nowadays people use technology to automate their tasks.
Cameras present in particular places are greatly helpful, as
users can monitor the feed and record video.
The sensors automate the task of alerting the user via mail,
mobile applications and various software’s. Since, the
sensors can be used to detect activity and perform
predetermined tasks. The task can be ranging from simple
in nature to complex tasks [1]. Next generation appliances
are developed with the thought of automation in
consideration. Sensors can sense the temperature, gas
leakage, humidity, light etc. increasing functional abilities
to include smart alarm systems, and controlling the
household appliances from a remote location. These
systems are specially designed for home automation with
some increased functionalities and using Internet
connection protocol i.e. Wi-Fi as a connecting link between
the device and the user [2].](https://image.slidesharecdn.com/irjet-v7i2326-201120055352/75/IRJET-Raspberry-Pi-based-Intelligent-Security-System-1-2048.jpg)

IRJET - Raspberry Pi based Intelligent Security System
This document summarizes a research paper on an intelligent security system using a Raspberry Pi. The system uses an RFID card reader and OTP authentication for authorized users. For unauthorized people, a PIR sensor detects motion and sends a photo using a connected camera. Two administrators can review the photos and unlock the door remotely if needed. The system aims to provide all-round security while maintaining user comfort through multiple layers of authentication using low-cost hardware like a Raspberry Pi, RFID reader, PIR sensor and camera. Block diagrams and flowcharts illustrate how the system components work together to automatically detect and identify visitors while allowing remote authorization of access.

And the camera starts recording until the timer reaches 0. If no RFID input is detected the user is alerted of possible intrusion. If RFID input is detected the recording stops after 60 seconds and is stored in the database. Each RFID Tag is distinct for each user. The user inputs its user specific password as doing such the user can be identified. After giving the correct password to the system an OTP is generated and sent to the user registered mobile number to increase security. After the OTP is entered correctly the relay gets activated and the door is unlocked. 5. FLOWCHART Flowchart 1
