INDEX OF FIGURES

No table of figures entries found.

[The list of figures above is created using Word’s Table of Figures (TOF). The benefit of using TOF is

automatic update for page numbers. To create a TOF, you must create captions for all figures. To create

a caption, highlight a figure and go to References and Insert Caption. The dialog box will appear. Under

Options, choose Figure and a position of caption e.g., above a figure. Under Caption, write a caption

e.g., Figure 1: Figure 1 title. After applying captions, put cursor on the list of figures page, go to

References and Insert Table of Figures. Under General, choose Figure for Caption label. To update, right

click, select Update Field and choose one of the two options.]

[You might have to adjust “Caption” style. To do so, right click “Caption” style and choose Modify. You need to adjust only once]

Introduction

Project Introduction

Imagine coming home after a long day of work to a house that has been burglarized, or

going to bed at night with no sense of security and having the thought of someone breaking

into your house and possibly harming you or your family run through your mind. According to

the FBI, there were an estimated 2,103,787 burglaries in 2012, a decrease of 3.7% compared to

2011. Compared to 3.7 million household burglaries each year on average from 2003 to 2007.

In about 28% of these burglaries, a household member was present during the burglary. As you

can see the amount of burglaries has had a steady decrease in the past decade but they’re still

occurring at a very high rate. Home intrusions occur every 13 seconds in the United States. Your

chances of becoming a victim can be severely decreased by having a home security system.

Surprisingly only 17% of homes in the United States have security systems, meanwhile homes

without security systems are up to 300% more likely to be broken into. Many people choose

not to have these systems because they’re either too expensive or too complicated to use.

Others rely on the protection of having home insurance but sometimes buglers steal things that

have sentimental value and can’t be replaced. Almost all home security systems available to

consumers require monitoring by an outside party such as ADT and ESCO; these outside parties

usually charge an installation fee and a recurring monthly fee. Our design called The Smart

Security System (SSS) will allow home and business owners to monitor their homes and

businesses via their smart phones. Activating and deactivating the sensors will be done via their

smart phone wirelessly using Wi-Fi technology. This allows them to have control of the system

regardless of where they are. Our system will include a motion sensor, gas/smoke detector,

Page | I I

temperature sensor and built in camera. Almost all the security systems available in the market

today only come with motion detectors and the rest are sold separate at an extra cost to the

customer. With our design customers will only have the one-time cost of the device with no

installation fees or reoccurring monthly fee, this allows them to save hundreds each year. The

SSS will be more convenient and portable since every component (such as motion sensor and

camera) will be built in one device allowing customers to self-install the device.

Technical History

In recent years, home security has moved away from simple control panels and deadbolt

locks to high-tech security technologies that are composed on many homeowners’ wish lists.

Today’s security systems are not simply the product of technological developments of the past

few years, but the combination of experience and hard work throughout decades. To understand

how home security became as what it is today, we should take a look back to the past.

The increase in crime after World War I resulted in Americans becoming sensitive to

security needs and they were willing to find methods to keep themselves and their property

secured [1]. Additionally, many insurance companies stepped in, offering premium discounts to

alarm subscribers. During this time period demand for alarm systems had begun to peak and the

American telephone companies introduced emergency call systems that invited police and fire

fighting personnel into the security system era [1].

Although video surveillance technology was developed in the 1940s, it was not until the

1970s that it was used in homes as a security measure. After World War II home security

systems became less expensive and more versatile for use in 1980s [2]. Early advanced home

security systems included bulky camera that would be motorized and moved down a track to

Page | I I

view the outdoor of the home throughout eyeholes mounted in the front door [2]. The video

cameras transmitted rough images of visitors to a stationary television monitor that also served as

the control panel where the homeowner could remotely control the camera’s movements.

Now days, surveillance cameras are as small as one square inch and connected to the

Internet. These camera can be outfitted with powerful lenses that can capture and stream high

definition video online that can be viewed from anywhere in the world. The signal is transmitted

wirelessly to the user. Additionally, with a connected smart home, homeowners can program

their security systems to send a live video clip of an area if motion is detected when the home is

unoccupied and the alarm is activated. Some systems not only can warn you of intruders, but also

can notify authorities of a medical emergency, monitor smoke, and carbon monoxide and water

levels or pressures. Some systems also are linked into your home's wiring, heating or lighting

systems and use your mobile phone, device, or computer to control them [3].

Technical Research

Home security systems work on the simple concept of securing entry points into

a home with sensors that communicate with a control panel or command center installed in a

convenient location somewhere in the home [4]. Sensors are typically placed in doors that lead

to and from a house as well as easily accessible windows, particularly any that open, especially

those at ground level. Some systems not only can warn you of intruders, but also can notify

authorities of a medical emergency and monitor smoke and carbon monoxide levels. Some

systems can be linked into your home's wiring, heating or lighting systems and use your mobile

phone or computer to control them [3]. There are a few companies that provide the similar

Page | I I

features in their home security system but they require multicomponent such camera, smoke

and carbon monoxide and even a pin pad to activate and deactivate the system.

ADT and Brinks are just a few companies that provide many useful features but they

also offer separate components and you have to pay each month to keep your system up and

running [5]. ADT provides 3 different security plans, first is a basic home security with gives you

a few good features for less cost. If you want their best features which include remote alarm

system and live video, it will cost you a lot more than the basic plan [5]. Another company that

provides home security system is Brinks. Brinks has many useful features in their security

system but same as ADT if you want the high end security features you have to pay more [6].

Our Smart Security System offers advantages like video surveillance, a smoke detector, carbon

monoxide detector and a temperature/humidity sensor all built into one device. Also the

activation and deactivation of the system will be done through a mobile device or smart device.

The best thing about our system is that you don’t have to pay a monthly fee, it’s a once time

cost and total monitoring/control is done by the owner.

The system that we have designed will operate off a battery or it will have backup battery in case of an emergency. The system that we have designed is very efficient because it only needs 5V maximum to power the entire system so that means we could use a 9V battery to run our system which makes it more portable. The weight of the system will be 453 grams so it will be able to be mounted to the ceiling. The system will be able to provide the user with visual images that will be supported by all smart phones such as Android, IOS, and Windows. The security system will be connected to the internet though W-FI but controlled by a smart phone at all times.

Constraints of the system
