CHAPTER 1
INTRODUCTION
1.0. Introduction
In a situation where there is high level of thief, there is need for better security system [1]. There is a growing interest in intelligent home network as a way to offer a comfortable, convenient and safe environment for occupants. In order to enhance the occupants convenient and safety, home security system is important in the field of intelligent home network. The requirements of a home security system include low cost, low power consumption, easy installation and rapid response to alarm incident [3].

wireless technology has some remarkable benefit comparing with non-wireless technology. Research shows that Bluetooth, Zigbee, 802.11 and wireless USB are the most popular technology in the field of wireless network. However, the technology that has been mentioned is high in power consumption, high in cost and don’t present the implementation.

GSM is a digital mobile phone system, operating in several frequency bands. Most knowing bands are 900MHz, frequencies, 1800MHz but also in the bands of 1900MHz and 2100MHz depends on their memory cards called SIM (Subscriber Identity Module), which provide user identity to network with their telephone number assign [2]. GSM provide the highest quality data calls, and moreover, offer the possibility of using the same mobile phone (with the same SIM card, and hence the same number) and other network around the world (roaming) so that the user can be found even if it is not in the country. The GSM itself consist of the interconnected cell. Each cell corresponds to a specific antenna (base station), placed on towers or tall building to avoid a near-immediate access to their public persons.

To detect any activity such as open door/window, the reed sensor is used. This project will help the alarm systems exist today more efficient since the user/owner can get the notification immediately as the reed sensor is triggered simultaneously with LCD display by the microprocessor. Not only that, by display the warning signal using the LCD display, people surrounding will notice immediately which house/premise has an intruder. This is the important of this project which it is affordable to most people. People will not only can hear, but also can see the warning signal. This is the adding value of this product because it helps people with hearing problem to contribute/take action when he/she are at the incident site.
After some research, the reed sensor is the best sensor that can be used for this project. There are many sensors that can be used such as PIR sensor, but research finding that reed sensor is more suitable since it can act as a switch. This magnetic switch is employed as magnet-sensitive contactless bi-stable limit switch. More about this sensor will be discuss in Chapter 3.

1.1. Objective
The aim of this project is;
i. To send the notification to the owner.
It becomes more crucial to inform the user in real-time when the alarm system is triggered. By using the GSM modem, the notification /message can be sent to the user when the alarm system is triggered. When the sensor detects the intruder/theft, it sends the data to the processor to process information, and send message to the owner via GSM modem. User will get the message through the phone.
ii. To display the warning signal
The adding value on this product is the LCD display. This will make people more aware about the current incident. Not only that, people with hearing problems can also react with the situation because she/he can see the warning signal from the LCD. This product will not only send the message to the user, the warning signal also is displayed through the LCD display. This LCD display is placed at outside of the premise/home. By display it, the people at surrounding can see easily where that sign is come from. So the information can transfer smoothly.
iii. To make the security alarm more efficient.

1.2. Problem Statement
The security systems nowadays are too expensive to most people that have middle income. Research find that for ADT alarm, the moderate cost is around RM900.00 and above. Next, security alarm that exists also can’t make the people on surrounding to be aware to that warning sound. People sometimes would get confused to detect the exact location of that warning sound. Not only that, in real world, when the alarm system is triggered, people will automatically assume that the alarm system is broken or is being fixed by the user. At this point, it can be seen the alarm system that exist today not efficient in term of information transfer. The most important things is, today alarm system failed to inform the owner about the incident. Try to guess what happen when the alarm system is triggered at midnight? There will be no people surrounding to react with the situation. This problem becomes more serious when come to public holiday, such as Hari Raya where most of people will back to their hometown for a several days. The user will not notice it until the time he/she come to premise/home. This make the alarm system is not efficient enough.

1.3. Scope of Work
The aim of this project is to send the notification to the owner simultaneously by display the warning signal through LCD display. To make this project work as mention, both hardware and software are needed. The software that will be used in this project is CCS Compiler and Proteus. All the program code will be design in the CCS Compiler. The circuit is design inside the Proteus software. So, to test whether the program code that has been design is work or not, the program code is then transfer into the processor in the Proteus software. Then, to get the desired result, run the circuit. This both software are depends to each other.

When the system consist of hardware and software function properly, the model for the project is then can be design. Below is the design of the model.
