Abstract

In this project, a multilevel home security system (MHSS) has been designed, developed,

tested and validated. MHSS is basically a multilevel security system which consists of

different sensor nodes as the input elements while the output elements react to the signal

received from the input elements. The sensor nodes consist of a thief alarm, presence

detecting circuit and the break-in camera. A UART is applied as the communication tool

between the hardware and the computer. A graphic user interface (GUI) is developed and

configured which enables the function of capturing images and sending emails. The captured

images are delivered to the house owners and the police forces. The task is performed in

order to prevent the thieves’ invasion.

Keywords: Home Security System, Sensor Nodes, PIC and UART

1. Introduction

Home security has been a concern of worldwide. As the technology is emerging

every second, abundant home based security systems have been developed and

implemented to keep their welfare safe. Home security system is an essential mean of

protecting our home from illegal invasion. A conventional home security system

consists of a Closed Circuit Television, CCTV and burglar alarm. CCTV captures

video in 24 hour to identify what goes on around the house and in the house as well as

get a hold of the evidence if there is a house breaking around the captured areas.

Burglar alarm acts as the tool to alert the house owners and their neighbors. In

additional, it may also chase away the burglar as the system may emit a high frequency

sound wave. Nevertheless, the memory consumption is considerably large as the camera

keeps recording non-stop. The power consumption is considered as a concern of

installing a security system. In this project, a multilevel home security system that

sends alert messages to the house owner and police station has also been designed,

developed and validated. Section 2 introduces the background of the project. Section 3

introduces an overview of MHSS. Section 4 and 5 discusses the system implementation

and hardware & circuit testing respectively. Section 6 makes the conclusions of the

project as well as highlights the future work.

2. Background

2.1. GSM/GPRS Based Security System

Based on the IEEE802.11 standard, wireless home network is known as WiFi, which

provides a medium for transferring media files [1]. However, it is high cost and high
