I. INTRODUCTION
Security and safety are one of the common issues
that brings worries for human being. As Security of
human life and property is one of the paramount
challenges facing nations and corporate organization
[17]. Home security and possessions can be one of
the most essential challenges faced by individuals,
corporate organizations or any other nation [2].
Human lifestyle, behaviour and thinking in modern
society is changing radically with the advancement in
technology, and the simple home is changing into a
smart home. This is due to advancement in
technology which has increased the safety and
security of people along with their belongings.
Doors are entrances to homes, offices and many
other kinds of enclosure; they may also provide
access for visitors, lawbreakers and criminals. Doors
are meant to be secured and to prevent intrusions
from unwanted persons; and are controlled majorly by
locks and keys. From time past until present, security
locks usually include mechanical devices made of
forged metal such as simple lock and bolt, the door
chain, pin tumbler lock, the jam lock and padlock [6].
The common way everyone is familiar with is using
physical keys to lock or unlock door, but this tested
and known method comes with it challenges. There
can only be one unique key for a lock. For different
locks you have different keys. Furthermore, carrying a
large number of keys is a burden and increases the
chance of keys getting stolen, misplaced or lost [7].
People always remain busy in their day to day work
and also want to ensure the safety of their belongings.
Sometimes they forget to look after their necessary

things like keys, wallets etc. Without these, they are
unable to access their home or any place they access
using keys.
In this modern world with already more than
7billion human population, expected to exceed
11billion by 2100 to be living in the world [28], crime
has become ultra-modern in nature, theft and home
abduction is on the rise by day. Which has raised
question about doors and the safety of homes and
other kinds of enclosure. Individuals and cooperate
bodies are becoming more aware of the dangers
associated with relying on keys and parameter fencing
to provide security to exclusive areas of their
apartments and organization because criminals and
fraudsters can forge keys or make master keys that
can be used to break into such rooms or offices. So,
security does matter in this daily life [1]. The
disadvantage of traditional lock is that when
homeowners lost key and have no alternative key,
they have to wait for long hours for a technician to
come, otherwise they will have to break the door or
lock. Another challenge with keys is that key may be
locked away or maybe misplaced inside the house, in
this case even authorized persons won’t have access
to his/her property or belongings [2].
The function of pad lock and jam lock is to prevent
an unauthorized person from gaining access to a
place. [6] say that the simple jam lock and pad lock
can be forced open or the keys duplicated by
unauthorized persons which is however classified as a
loop holes which give an unauthorized individual
access to where they are excluded. Therefore, they
cannot be completely relied on. It is hence vital to
provide a smart security door, one which is also
efficient and reliable; with high discriminative
capability, non-reliance on the physical quality of the
individual concerned, does not have key access or
any physical locking interface and which is by far less
expensive than their counterparts [13]. There are so
many systems already existing in the society to
provide security, among those the microcontroller-
based door lock system is one of the best methods to
provide security [15]. The smart door lock system
requires adequate security for user data control,
monitoring and securing every device itself. There are
several advantages of smart lock system, being that, it
is secure, unapproved individuals won't have any
means of accessing the home and there is no
requirement for a key. The main thing which will be
required is a smartphone to call the door with the
required app installed.
Considering current global security challenges
around, the importance of a real time smart door and
security system is important. This paper presents the
development of a prototype smart lock with embedded
spy camera system by presenting the concept of lock
system. The development of the basic component to
achieve the prototype will also be presented. The
experimentation of the system and the result which
was the prototype will be presented (in plates) and
discussed.
II. RELATED WORKS
[18] proposed a low cost and low complexity
microcontroller-based door access control system, a
security door system which adopted a valid smart card
to authenticate and/or deny entry to a room or
building. A smart digital door lock for home
automation was proposed in the work of [19] their
work embedded Zigbee module in a digital lock
equipped to use digital details like secret code, smart
card, and finger prints as the method for
authentication instead of the mechanical key system
and the door lock acts as a central controller of the
overall system. [11] designed a storage locker system
using the biometric technique of fingerprint recognition
as a means to activate the opening and closure of the
lock. [29] prototype a security door that can be
remotely controlled. A GSM phone set acting as the
transmitter and another GSM phone set with dual tone
multi-frequency (DTMF) connected to the door motor
through a DTMF decoder interfaced with
microcontroller unit and a stepper motor.
[16] designed security door that opened by
pressing the keys of the assigned codes on the mobile
phone, or by entering the corresponding code in a
computer set interfaced with the system. The door
opens automatically when the right code is entered
and remains open for 10 seconds before closing back.
[8] designed a GSM-based biometric access control
system. The Fingerprint Scanner automatically scans
a finger placed on it, and compares it against its
template. The GSM module is used in the
acknowledgement mode to send an Access Request
SMS to the Admin Phone. If the admin acknowledges
the request, the microcontroller opens the door and
displays “access granted”.
Other smart lock system has been built
around Bluetooth and Radio frequency identification
(RFID) technology. [22] was based on short ranged
Bluetooth Technology on Android Mobile devices for
door lock security and controlled using android
application. [26] work was based on video technology
stored in cloud along with Bluetooth technology on
Raspberry Pi for communication between visitor and
owner as a security feature. [12] presented a
prototype system of door locks automation system
using Bluetooth-based on android Smartphone. The
design is the combination of android smart phone as
the task master, Bluetooth module as command
agent, Arduino microcontroller as controller
center/data processing center, and solenoid as door
lock output. [10] implemented lock system using
Bluetooth Technology Android based smart door lock
system with multi-user feature for a single lock. [24]
uses an Arduino having an HC-05 wireless Bluetooth
Transceiver for controlling door. The application uses
Arduino as its controller and HC-05 as a
communication link between mobile applications. A
cellphone-controlled password-protected door lock
system was proposed in [1] to open door with the help
of an Android app that generates a password
recognized by Bluetooth to control the opening and
closing of the door located at some distance from the

user. [20] proposed android based smart door lock
system with normal mode and multimode user
operations, combining the use of GSM module,
Electric Door Strike, and Bluetooth HC-05 interfaced
on an Arduino Uno Board.
[30], [31], [32] and [23] made improvement not
using only RFID but advanced the security level by
adding fingerprint and GSM mobile system, [19] build
up with the addition of DTMF and GSM system, and
[14] system uses RFID and GSM mobile system, [5]
uses the RFID and GSM mobile system but ensures
that users are informed about the level of operation of
the system by displaying operations on the LCD. [13]
designed an automation system based on wireless
technologies. Door opening and closing was
controlled by RFID, ZigBee and GSM. [9], designed a
system in which the user unlocks door using RFID
system and SMS code in case of card failure using
GSM protocol. The system also uses a live streaming
camera. DTMF is used to access the lock of the inside
doors of the infrastructure using cell phone of the
authorized person. [4] designed a RFID smart system
using GSM and password for security purpose in
operating the functions of a smart door.
The advancement in technology calls for more
security level with smart doors, [25] proposed an
automated door control system employing Wi-Fi as
well as GSM technology built around Atmega8
microcontroller. [21]design an IoT smart door locking
system using finger print sensor, Bluetooth HC-05 and
Servo motor interfaced with Arduino board. The
system uses finger sensor to read identity to know if
there is a match between a scanned and already
stored finger print. Then the Bluetooth is used to
activate the door control. [27] worked on IOT based
smart door lock system their work installed a servo on
door and interfaced buzzer and keypad on Arduino
board. In the system user is expected to enter a PIN
code for a verification system. The PIN is verified and
afterward the door is either unlocked or a buzzer
sounds an alarm calling attention and the door
remains unlock to the visitor. [2] implemented a real-
time door locking security systems using Arduino Uno
R3 as the main microcontroller interfaced with
Fingerprint Reader R305 scratch-resistant sensor with
image resolution of 500 pixels per inch and Door lock
solenoid (NC-0837L) for opening and closing of smart
door.
Considering the trend of global security
environment, the importance of good physical security
is imperative. Initially, normal key locking was the
security locks used to restrict entrance, but were
hacked by unwanted people by either duplication of
key or physical means. There were several automatic
identification technologies including barcode,
magnetic stripe and Radio-frequency identification
(RFID) system that were applied in security system,
though with limitations. With technological
advancement, electronic automatic identification
systems with varying degree of security feature were
deployed to restrict entrance.
This paper presents the development of a
prototype RFID-GSM Based security Lock System by
presenting the concept of lock system. The
development of the basic component to achieve the
prototype will also be presented. The experimentation
of the device before achieving the desired device will
also be presented (in plates) and discussed. The
result which was the prototype of the device will be
presented (in plates) in sequential order.
III. SYSTEM STRUCTURE
The smart door lock system with embedded
spy camera integrated with other wireless
components was employed in this system. The
system coding and development for the smart door
involves integration of both hardware and software
system design. The embedded software coding was
implemented in Arduino integrated development
environment (IDE) using C language. The smart door
lock system operates over WIFI network, GSM
Module and Mobile App. This system is friendly to
operate. When the system is power ON, it initializes
all the modules connected to it which includes ESP-32
Cam, solenoid electric door latch, buzzer, SPST and
SIM 800L GSM module. The smart door when
powered on put a call across to a registered number
to alert the home owner that the door in powered on.
The smart door systems allow the user to either call
the door, use a mobile app or uses the system IP and
password before further action is taken. If any of the
above step is valid, the door will be opened and if all
attempt failed the door remained closed. Figure 1
shows the block diagram of the smart door system
embedded with a spy camera.

The whole circuit was developed around a
constructed Arduino Uno (ATMEGA328P) board and
all the input-output devices including ESP32-CAM,
Sim 800L GSM module, Single pole single throw
(SPST) button, solenoid door lock and three LED
indictors were connected to it via jumper wires. The
circuit was powered by +12v AC power supply units
and a backup battery in case of power outage. The
LEDs were used as indicators in this design, the Red
LED indicates Power On status, the Amber LED
indicates state of WIFI connection and the Green LED
indicates the status of smart Door working. The time
of Door Locking operation can be extended or
reduced by altering the delay values in the firmware.
Initially the experimental set-up was developed as
shown below in Figure 2a and 2b.

Workings of the Smart Door System
The implementation of the smart door system with
embedded spy camera provides a 3-level of user
authentication module which can be used to access
the door at any giving period of time from any location.
This system has been able to implement a system
based on WIFI, GSM Call and android mobile Apps-
based authorization for system resourceful, privacy
and trustworthy of the home users or administrator
and provides adequate security level against
intruders. These 3-level stages are illustrated below.
To enable the working of the door, the power adaptor
which is a 12V adaptor is connected to power source
and the power button is switched on, the system
initialized all other hardware, establish connection with
the internet, then give a voice sound “Smart door now
ready” and puts a call across to a registered number
to tell that the smart door is ready to work.
i. Testing Camera View of Visitor at Door
Environment
Plate 1a shows the initial configuration for the door
camera view of visitor at the door before the buttons
are embedded to be a single button illustrated with
Plate 1b. The smart door can be opened to a guest
through a defined webpage to the display screen of
the visitor or intruder at the door. Here the smart door
greets the visitor based on the time of the day; this
stage makes use of the ESP-32 CAM and WIFI
function to transmit the environment feature to the
home owner. Where the home owner wants to grant
entrance to the visitor, the home owner automatically
opens the door to the visitor by dragging the center
button to the right hand side of the screen either on a
mobile phone or personal computer, else the owner
ignores and watch what action the visitor is about to
perform to make a decision of alerting the security
agency for prompt action. Furthermore, the camera
view option also ensures that a person at the door is
not forced to have the door opened to gain unlawful
entrance using a visitor as a pass.

ii. Opening the Smart Door through Mobile
Application
Plate 1 shows the working of the smart door lock IP
address and password screen that can be used to
unlock the door. Here the user is expected to enter
the smart door IP address and password to the door
on the mobile app then press the “OPEN” button to
enable the door opening from any location. If a valid
IP address and password is entered through the
phone mobile app by the user, this will control the
door opening (access granted). Also, if an invalid IP
address and/or password is entered, it will deny
guest/user access to the entrance of the building.
Plate 1 Mobile App IP Address and password screen
iii. Opening the Smart Door Through GSM
Call
Plate 2 illustrate the opening of the smart door
through a GSM call. The smart door can be opened
by simply calling the door through the phone of
enrolled user of the smart door. This authentication
mode allow access to the door where Internet network
connection to the door failed and this gives answers to
the problem highlighted in research work on the issue
of failed biometric enrollment of a smart lock user.
Where a call is made to the door, the microcontroller
authenticates to see if the call is from a registered
user, where it is confirmed the door is opened and if
otherwise, the door remains unlocked.
Plate 2: GSM call to Smart Door Screen
iv. Using of SPST (Single Pole Single Throw)
Internal Press Button
Plate 3 shows the illustration for the opening of the
smart door from the inside to a visitor when the home
owner is inside the building which is another mode of
operation of the door. This allows the user to press a
SPST (Single pole single throw) button without
necessarily using the other mode of operation
available for the opening of the smart door. Although
with this level the user may choose to view the video
of the guest at the door before making decision to
open the door or not to open the door to the quest.
The use of press button also relieves the user from
using other options from inside.

IV. DISCUSSION
The smart door lock system was implemented by
integrating the ESP-32 CAM an AI thinker with spy
camera with Arduino Uno (ATMEGA 328P) as
illustrated in Figure 1. This system is strictly design for
access control of opening and closing of door through
WIFI, GSM Call, SPST Button or web app
authentication/authorization techniques.
In gaining access to enter through the door, the
home owner uses either of the four (4) methods to
grant access. If a call is received from a registered
number this will control the door opening and grant
access else if an unregistered number calls the
registered number of the door, the door remains
locked. Also, when command is received from the
camera view button from a browser using the right IP
address the door also grant access. The door can
also grant accessed through a mobile app installed on
the registered owners phone by entering the IP
address and Password of the smart door. As a mean
of granting entrance access to the home when home
owner is within the building, a SPST (Single pole
single throw) button can be pressed from within the
home from the inside to grant access. The first three
methods allowed owner to be able to remotely access
the smart door from any location while providing
proper monitoring mechanism for the door. A
prototype of the designed smart door is shown in
figure 3 while .Plate 4a and 4b showed the camera
view of a visitor both at the door environment and on
the webpage

V. CONCLUSION
In this paper, the design and construction of a
Prototype smart door lock with an embedded spy
camera was presented. The methodology used in
achieving this smart lock system was also discussed
using block diagram. The various methods of the door
operations using Camera view and button, STSP
button, GSM call, and Mobile App were tested and it
was successful. Plates of the prototype of the smart
lock system were presented and discussed. Though it
may be impossible to guarantee absolute security,
threat identifying and risks of this system are vital
