Design And Construction Of An Intruder Detector System With Sms Alert

ABSTRACT

This work is on a GSM-based home intrusion detection device. The GSM-based home intrusion detection device is a security device that sends a text message to the owner’s mobile number in case of home intrusion. This system was built due to frequent and widespread cases of burglary in homes, offices, factories etc. is on the increase. The advancement in technology has intensified such that motion can be detected by electronic device that calculates and measures changes in the given environment. This project is designed and constructed using an ATmega8 microcontroller, system connected to a GSM module with SIM (subscriber identification module) from a network provider. Light dependent resistor (LDR) sensor which is used in this project is connected To a microcontroller unit, GSM module and other electronic devices which detects any intruder in a classified area and then activates the alarm system and sends out text message notifications to the house owner specifying the location and time of intrusion to the programmed phone number of the house owner. The initial testing of the design shows that it worked in real-time in area with good network coverage as expected. It has wide range of application in surveillance especially in industrial and home security, especially when internet connectivity is not available.

INTRODUCTION

1.1     BACKGROUND OF THE STUDY

The efficacy of our security system has been in question over the last few years owing to the wide spread of global crime that has rendered many establishment, business place and home crippling. Despite all effort security operative and their counterpart had put in place to moderate burglary and intrusion, yet crime rate and intrusion are still high. It had been observed that as the population increases and employment rate decreases, it leads to a corresponding increase in crime rate (Aayush,2012). Therefore there is need to employ a more effective, efficient, reliable, cost effective and less time respond technology or measure to tackle and reduce the crime wave to a bearable minimum to achieve a peaceful society.

An Intruder Detecting System (IDS) or device is a techniques used for detecting intruder actions (Abhishek and Amol, 2015).  Intrusion detector is a device or software application that monitors network or an area or system activities for malicious activities or policy violations and produces alert, or reports to a management station. Intrusion prevention is the process of performing intrusion detection and attempting to stop detected possible incidents (Abhishek el al, 2015)

Intrusion detection and prevention systems (IDPS) are primarily focused on identifying possible incidents, logging information about them, attempting to stop them, and reporting them to security administrators. In addition, organizations use IDPSs for other purposes, such as identifying problems with security policies, documenting existing threats, and deterring individuals from violating security policies (Sadeque, 2012). IDPSs have become a necessary addition to the security infrastructure of nearly every organization.

Security is the degree of protection against danger, damage, loss or any criminal activity. Security can also be seen as a condition in which one can develop and progress freely (Asogwa, 2013). An important aspect of security includes home security. Intruder detection system is very important because crime rate is increasing day by day. The advancement of technology has increased the safety and security of people along with their belongings. One of the reasons for the rise of the smart home device is the increasing risk of burglary and robbery and the busy time of the day.

The busy lifestyle of people during working hours or travel period is leading to the neccessity of controlling home remotely and increasing the neccessity of keeping surveillance over their homes (Nwalozie, Aniedu, Nwokoye and Abazuonu, 2015). Mobile phones today are not just used to make calls. The use of mobile phones is changing with the development of technology and they can be used for different purposes. They can be used as clocks, calendars or controllers instead of being used just as phones (Nwalozie  et al, 2015) . Today smart phones are available in the market with different applications and hardware which can be implemented without any further development or enhancement.

With the help of the global system mobile for communication (GSM) network, a mobile can be used to implement a smart home by controlling devices and getting alerts on intrusion, burglary and robbery (Abhishek and Amol, 2012). Traditional household security systems often require installation and detect based on opening of doors and windows. The increasing number of the stealing and house breaking cases especially when the people are not at home need a system that can call or  tell owner if anyone has attempted or trying to break into their home. Therefore the idea of a smart home system was proposed, to overcome the limitations of the systems already available in the market.  Hence the GSM-Based Home Intrusion Detection Device is a security device that sends a text message to the owner’s mobile number in case of home intrusion. This is to warn and notify the owner of an impending attack. It is useful when the owner is outside the house, or even when asleep. It is pre-programmed to store the owner’s mobile number in which the device would send a text message notifying the receiver of an intrusion. The device uses a GSM modem which requires a subscriber identification module (SIM) card to send text messages. The device is to be placed adjacent to possible entries of intrusion, such as doors and windows. The device is activated once the door or window is opened and it automatically sends a text message which is also pre-programmed. The user can choose the number of sensors, types of sensors, the area of coverage of the systems along with the number space. The goal of the project is to implement a smart home system by controlling the electronic devices at home remotely with the help of a mobile device and getting alerts on intrusion or movement around the restricted premises. The design based on short message system (SMS) and uses GSM (Global System for Mobile communications) technology to send the SMS to the owner via the emergency number which is provided to the system. This proposed system is made up of three components: light dependent resistor (LDR) and passive infrared (PIR) sensor, GSM-GPRS Module (sim900a), Atmega8L microcontroller, relays to control the device and buzzers to give security internationalists of sound.

1.2     PROBLEM STATEMENT

In offices, residential building and industries, the potential for intrusion and thieve is always there. This could be carried out by close associate or stranger. However intrusion, burglary and thief has been a big challenge prompting engineers to develop a system called “intruder detecting system” helping to reduce intrusion thieve. In modern technology advanced system had been developed to improve the standard of intruder detection / protection system. The system will not only detect intruder by sensing their motion or presence, but also alert the occupant of the building and immediate neighborhood of intrusion through SMS and alarm system.

1.3     AIM AND OBJECTIVES OF THE STUDY

The main aim of this work is to build a GSM-based intruder detector system. The objectives of the study are:

1. To save lives and properties
2. to monitor our environment

• to evaluate the performance of the system

1.4     SIGNIFICANCE OF THE STUDY

The following are theSpecific objectives of the study:

1. Create a device that triggers whenever the home security is bridged
2. Use GSM technology in sending notifications to the security administrator’s mobile number notifying him of a possible intruder to home.

1.5     SCOPE AND LIMITATIONS OF THE STUDY

The scope of this work covers building a security device that provides intruder detection and alarm system for individuals and industries that sends a text message to the owner’s mobile number in case of home intrusion. The device uses a GSM modem which requires a subscriber identification module (SIM) card to send short message service (SMS). The device is activated once the door or window is opened and it automatically sends a text message to the security administrator.

However, there would be possibility for expansion to cover other areas like laboratories, offices, bank vault and restricted areas like high tension voltage areas as well as radioactive areas.

1.6     DEFINITION OF KEY CONCEPTS

The key concepts associated with intruder loop detection system are:

1. Intrusion:is an illegal act of entering, seizing, or taking possession of another’s property.
2. Intrusion detection system: is a device or software application that monitors network and/or system activities for malicious activities or policy violations and produces reports to a management station.
