THE PROBLEM AND ITS BACKGROUND
This chapter covers the introduction, background of the study, objectives of the study, scope, limitation and delimitation of the study, and significance of the study.
Introduction
Security has been one of the major concerns of today's daily living. Home and business industry’s security issues become a major concern since everyone in the industry wants to protect their investments from any form of destruction or loss. In terms of security, technology has its own contribution in developing equipment with a better degree of providing security and monitoring a given area or establishment that requires security.
Security systems consist of alarms and sensors which are being installed in the houses for effective and efficient way of protecting home properties. It is designed to detect burglar incidents. Security and protection system are any of various means or devices designed to guard persons and property against a broad range of hazards, including crime, fire, accidents, espionage, sabotage, subversion, and attack (Encyclopedia.org, 2014). One of the common security alarm systems that uses sensor is the car alarm system. Car alarm is a device in a car which makes a loud noise if anyone tries to break into the vehicle.(Collins Dictionary, n.d.) With these, an attempt for theft is immediately discouraged.
Most of the buildings install closed circuit television surveillance system to monitor and record the situation inside the building. It can oversight burglary incidents through its video records. However, in the proponents' view this type of system is not enough to give real time security to avoid damages of properties because the incident will be noticed only after the incident happened or after the video records were reviewed.
Most of the building incidents like burglary is being done in the presence of security systems is because the criminal knows that the system is not real time and just recording happenings. Therefore, these kind of people can plan on what they will do to be unnoticed. Because of this observation, the proponents have come up with the idea of developing a project entitled “Home Security System with Mobile Application for Fire Detection and Intruders” to enhance the level of security, to avoid damage to properties, and even for personal protection.
Background of the Study
As innovation takes its level to the fullest, improvements on systems development as well as its implementation have tremendously take its place as well. According to research on the crimes in the Philippines most of the crimes are index like theft and robbery. Moreover based on the statistics of Philippine National Police Crime and Investigation Detection Group about index crimes, an increase in the total crime volume in the first 5 months of 2014 compared to 2013, from January to May 2014. A total number of reported crime when it comes to robbery was at 5,189 compared to 4,510 in 2013.(B.Cupin, 2014) About 15% of total reported crimes is the difference of the reported statistics. This statistics shows that crimes still rise in figures even there was existing security system, while the Bureau of Fire Protection (BFP) NCR has recorded a total of 615 fire accidents in first two months of 2015 in Metro Manila (T.Macas, 2015). This shows that the existing system is not that too much helpful in reducing crimes and saving property damages on time.
This scenario gives the proponents an initiative to propose the project development study entitled “Home Security System with Mobile Application for Fire Detection and Intruders”. The study was a security alarm system that can be used for building and homes which aimed to provide real time security better than existing recording security system.
Theoretical Framework
The Fire Dynamics Simulator model (a LES-based CFD model) is used within this study to model the transport of smoke from the fire to the detector. In the FDS code (McGrattan ed., n.d.), a simplified low Mach number equation for fire and smoke transport calculation is used. In this approach, the acoustic waves have been filtered, but the flows are allowed to remain compressible. Hence, the time step can be increased to drastically reduce computation times. These simplified compressible flow equations are more computationally efficient for modelling fires and smoke. A Large Eddy Simulation (LES) approach has been used to deal with turbulence. LES solves the large eddy motions by a set of filtered equations governing the three dimensional, time-dependent motions. The small eddies are modelled independently from the 14 flow geometry. This algorithm was applied in the study because the proposed project used motion sensors for detecting human or intruder’s presence (Lobby et. Al., n.d.)
The Fire Dynamics Simulator and Large Eddy Simulation was used in the study because it gives the idea to the proponents on how they will convert the fire detection to signals that is usable for signalling the mobile application the proponents find out that they can use fire sensors that automatically convert it to logic signals.
The Proximity Sensor Algorithm is when the detected object is human skin, the design is somewhat simplified. Infrared light can penetrate human skin. The peak is shifted to a closer distance and the Analogue Digital Converter (ADC) count does not plummet at zero distance, with optimum optical designs, proximity sensing performance with other non-human sensing objects. The shape of this response allows for a simple threshold scheme to identify the proximity of a human (as in the case of answering a cell phone call). The low threshold must be high enough to ignore any changes in ambient noise. The high threshold must be low enough to withstand any changes in the peak output ADC count. The space between them must also be large enough to handle anyambient changes. (Intersil n.d.)
This algorithm was applied in the study because the proposed project used proximity sensors for detecting human or intruder’s presence at which distance was suspicious to commit burglar activity.

Conceptual Framework of the Study
Figure 1 shows the progress of the study, it shows the necessary methods that were taken into consideration. The phases namely, INPUT, PROCESS, and OUTPUT were introduced in the theoretical framework which shows the sequence of the procedures to follow until the development of the study. On the input phase, ideas and concepts can be acquired from the internet, books, and related researches that can contribute greatly in the making of this research. Furthermore, the needed information and appropriate materials follows. Thereafter, planning and designing the construction of the project comes next. The process includes programming and encoding. Lastly, testing and evaluation of results will be conducted.
Statement of the Problem
The main problem of the study entitled “Home Security System with Mobile Application for Fire Detection and Intruders” was on how the proponents would develop the system. To come up with the development of the project, the following were the specific statements of the problem.
Significance of the Study
This study is significant to the following:
To the home owners, this project will help keep their properties secured and safe.
To the law enforcers and fire fighters, this project will help them quickly monitor areas if some related crimes or accidents happened.
To the security personnel, this will help them respond quickly on unwanted incidents which may happen to buildings/establishments.
To the proponents, this project will help them in applying their knowledge in software development.
Lastly, to the future researchers, it will serve as reference material if they would conduct similar study.
Scope and Limitation of the Study
The scope of the study is to design the Home Security System with Mobile Application for Fire Detection and Intruders. The system consists of sensors using microcontrollers with GSM (Global System for Mobile) Shield. For the mobile device to be used in Android system. An accessing Operating System version 4.2 (Jellybean) with SMS technology was required. The programming language used was Java through Eclipse connected to the Android development tool. Arduino Application was required in programming the microcontroller and GSM Shield. The alarm system was only limited on detecting door opening attempts, motion and smoke. The mobile application can only receive SMS signal from the sensor once an activity was detected. An alarming sound would be emitted on the sensor and mobile device and the application would be opened as an indicator of a detection event. The application has a text messaging sending feature program to the government authority for a quick action. Moreover, the study was limited to security alarm system for confidential rooms only, inside the building or establishments and not applicable for other rooms and populated areas.
