Modern civilization is full of with home break incident and burglaries. So this will increase fear of their valuable property and their home. Then they will feel there are not be protected from the burglars. Anyone in the world wants to keep their home to be safe and secured from unauthorized access because it may damaged or stolen the most valuable properties by intruders. This expectation for protecting a home may increase the demand of sophisticated burglar system with advance features. These requirements for high tech home security system with automation facility will add demand for protecting home from intruders but the system should be capable of identifying the actual visitors from the intruders. This Mobile Home Security Management System not only protecting the home, but home appliances also need to be protect by more refined control system.
Basically home premises can be divided into four sections such as front, rear, left, right. If you have large area then you should organized those area as Zone. A zone can have two or more sections together. It is depend on your requirement. So then we can setup the sensors to cover the zones or sections. Zone or Section may contain one or more sensors according to the requirements. Each sensor will be triggered when it detect the motion. So that signal will be converted to the text message and send it to the desired mobile phone. The one of advantage of this system is house owner can use his existing mobile phone to get the security alert. Another important feature is verbal communication with visitor via mobile phone. Once visitor presses the bell switch at the gate, that interrupt will be informed to the house owner via text message. Then he can initiate a telephone call to a dedicated number which is configured for transferring voice traffic to the gate. So visitor will feel house owner is inside the house as well as this feature can be used to indicate that someone is inside the home, so you can cheat intruders and can protect your valuable properties. This project included the home monitoring system to monitor the home via internet. Other than the sensors IP camera will be configured around the home and inside the home as well. So modern IP camera features will add a valuable service to this project because of your home monitoring system will be capable of not only view the home premises but also hear the sound via internet browser. Most of IP camera has a built in microphone, email and ftp service and automatic infrared night vision function (Gadget-Spot, 2005).
Sending a text message is a simple human effort function but using that text message you can achieve the heavy task by integrating modern technology. So Mobile Home Security Management System is capable of controlling lights and other electronic devises in the home. If we consider the cost of this function is very low rate but you can protect your precious goods and you can save your money. This system can be converted to control electronic doors, windows and gates as well as heaters, cooling systems and any type of electronically functioning devises.
1.1. Aim and Objectives
In day to day it is increasing the number of robbery and house breaking cases especially when the house is along, so need a system to identify these cases when it happened. This project is aimed at designing a Mobile Home Security Management System that able to control the electronic devises vas text message, ability to initiate a verbal communication with visitor at the gate, to get a notification text message when there is an intruders and monitoring system via internet. This project will help to minimize the robbery cases either at homes, shops and offices. To achieve this aims I need to get through each objectives in below.
· Provide an interface to communicate between computer and mobile phone.
· Convert the text message into binary code which can understand by electronic devise
· Provide an service to control the parallel port
· To study about the electronic circuit with parallel port communication
· Provide a service with live video streaming
· To study about the sensor behaviour
1.2. Scope
This project will be a development project in software and electronic. The accuracy of the system may be depend on the electronic components and connected wires. Passive infrared motion detection sensors are using for detect intruders but it also has a limitation intruders can detect those infrared rays by wearing an infrared active classes. Another problem, is the infrared rays’ architecture intruders can come close to the target, when uses passive infrared sensor. In passive infrared sensor is designed to get trigger when an object cross two infrared rays. In this type of project it is unable to use the active motion sensor because it is can be applied only for the entrances. Text message communication time will be depending on the mobile service providers` delay and performance of the computer. Video stemming also depend on the network traffic and internet 3G connection signals as well as performance of the IP camera.
1.3. Methodology
This project is to develop a Mobile Home Security Management System. This system mainly concern on security of the Home. So we need to find what the security requirements are. Find out the security requirement, questionnaire is distributed among the IT professionals and other professionals who are spending more times away from home. Then collected the security requirements from their answers and using the knowledge of electronic, the security system is designed to model the functionalities. A dongle is act as a GSM modem in this system. Once it received a text message, the message reads by Ozeki SMS gateway and the message transfers to the SQL database. Thereafter a new message reads by developed software and the software reads the corresponding a binary pattern from the database, then the binary pattern transfers to the parallel port. A developed circuit is attached to the parallel port, once it received new binary pattern to the parallel port, the circuit starts of corresponding electronic functions, as a result of that electronic device starts its job. For example switch on or off a light. Motion sensors and other type of sensors are attached to the circuit board, once any sensor is activated, that input is sent to parallel port by changing the voltage of a particular pin in status port of the parallel port. Then it feels to the running programme as an input, and then programme reads the parallel port. Thereafter programme searches text in particular table in database according port input and then that text sends as a text message to given number via Ozeki SMS gateway. Verbal communication and video monitoring system will run as separate functions. So there will not be any integration with security system.
1.4. Structure of Dissertation
Structure of dissertation may consist of details which have been to divide into chapters. In chapter 2 presents the background information about the developed home security systems and software which are currently in the market and also included the information that related to the subject matter with past research paper works done by professional by referring the literature reviews. Chapter 3 consist of requirement analysis of proposing solution for home security with clients` requirements and evaluating product in the market. Chapter 4 is used for design overview of the system. This design is based on the requirement analysis and electronic knowledge that I have. Chapter 5 represents the implementation of how system is working and it output reactions. In chapter 6 is presenting the testing and evaluation outputs of the system. This chapter may contain way of test the system in software and hardware parts and also user evaluation results of the system. Finally chapter 7 may presents the conclusion of the dissertation.
