Abstract


Security of life and property has been of great concern to people all over the world. Different approaches and devices have been put in place to ensure a high level of security as regards life and property. Governmental bodies have also put different forces in place to reduce the rate of crime in our society. All these and many more are the reasons for the choice of this project, computer controlled security monitoring system.

The project is an electronic circuit designed and constructed to detect motion of any kind of body across certain areas and then trigger an alarm which notifies people around of an intruder. Infrared transmitters and receivers placed at these points detect an intruder and hereby send a signal that drives a transistor and relay sub circuit which electronically switches ON an alarm circuit for an appreciable length of time.

This alarm circuit makes an audible sound during this period which can even be heard from a distance with or without the knowledge of the intruder. Apart from the infrared transmitter and receiver, all other circuit components are found inside a house shaped wooden casing located at one end of a board representing the area to be monitored.

Also added to the project is a computer interface circuit which connects the project to a computer system. With this computer system, the entire circuit can be turned ON or OFF from a remote terminal.

Introduction

1.0 Background Of The Project

Security Monitoring System is a type of electronic security device that senses movement and usually triggers an alarm. Many types of Home Security Systems can sense motion in total darkness, without an intruder becoming aware that an alarm has been triggered.

Security Monitoring System is an important part of most burglar alarm systems. They help alert security personnel, especially in situations where no obvious break-in has occurred. For instance, if an intruder steals a key to gain access to a protected house or hideout within the house, the intruder’s entrance or presence could go unnoticed. A Security Monitoring System will detect the intruder’s movements as soon as he or she walks or otherwise moves within the area protected by the detector.

Security Monitoring Systems usually protect indoor areas, where conditions can be more closely controlled. Detectors for use in homes usually detect movement in spaces about 11 m × 11 m (35 ft × 35 ft) in area. Detectors for large warehouses can protect areas with dimensions as large as 24 m × 37 m (80 ft × 120 ft). Buildings with valuable or important assets, such as museums, also use Home Security Systems to detect break-ins at vulnerable points. Such points include walls, doors, windows, skylights, and even air ducts. Special Security Monitoring Systems can protect the inside of exhibit cases where items such as diamonds are displayed. Others can be focused to a narrow area of coverage, somewhat like a curtain, that is projected in front of a painting to detect even the slightest touch.


1.1; Types And Operation Of Home Security Systems

Security Monitoring System uses a variety of methods to detect movement. Each method has advantages and disadvantages. Infrared detectors sense an obstruction of its transmitting signal when an intruder comes between the line of sight between its transmitter and receiver. Microwave and ultrasonic detectors are active—that is, they send out waves of energy and receive waves reflected back by objects. Any disturbance in the reflected waves caused by a moving object will trigger an alarm.

Video systems optically monitor an area, and movement is registered visually on a monitor. Often, these methods are combined to improve accuracy and reduce chances of a false alarm.

The detector used in this circuit is the infrared type only. It is employed in this circuit because of its reduced cost of purchase and a simple and comprehensive mode of connection and operation. Two transmitters are used here, one at the entrance of the house and another located somewhere beside the building. An obstruction in any of these areas alerts the housekeeper by signaling an alarm circuit located somewhere else.


1.2; Importance Of The Project

This project is very important in homes, offices and even other places where valuables are kept. One of the major importance is its computerized control so that the power of this circuit is controlled from the comfort of an office. When used in homes, the sound of the alarm can even scare an intruder without anybody being around the house. Nevertheless it is very important that this circuit is properly designed and mounted to prevent any form of false alarm.

Modern home security systems make use of several different technologies to reduce false alarms. Infrared detectors can be programmed to ignore the first movement detected, as in when the intruder moves from one detection zone to another, and to sound the alarm only when the movement passes through two or more detection zones within a specified period of time. In this way, an insect landing on the detector’s lens, or a sudden rise in background temperature caused by an activated furnace, is ignored.


1.3; Uses Of The Project

This project can be used everywhere including homes, offices, industries and others where proper security is to be ensured. In a wider view, this project can generally be referred to as motion detector. Apart from its basic use in homes as home security systems, Motion detectors have other various uses.

In manufacturing, electric eye detectors can count products on an assembly line, and perform other tasks that people would find tedious. Some dangerous machinery is equipped with active infrared or electric eye beams of light as a safety device. Should an operator’s hand get dangerously close to the machinery, the beam is broken.

The circuit is interrupted, and the machine shuts down. Garage doors with automatic door openers can be equipped with beams that sense a child under the door and stop the downward movement before the child is injured. Outdoor porch or patio lights fitted with motion detectors can be turned on automatically when motion is detected.

One of the most common and convenient applications of motion detectors is found at modern grocery stores, where doors automatically open as customers enter and leave.

How to nail it on the head during your project defence


You are through with writing that project. Now what?

You have found yourself at that point where you have to defend what you have written. Of course you have to stand in front of your supervisor and other literary personalities to prove that you know what you wrote in your project paper. Unfortunately, the more you think about it, the more it looks like you are about to face a legion. It is not a war. But the emotion of dread welling up inside of you makes it look like one. So now you are asking yourself questions.

  • How am I going to start?
  • I hope I will do well enough to get an A.

You really want to nail it, but you need to come to terms with exactly how to get everything in perfect control. Especially your emotions of fear that seem to make a wreck of you every time you think about public speaking.
So here is the deal. I want to help you avoid that feeling that would ruin your precious moment if you dare to let it. And we are going to do it together.

I am going to highlight some very important tips to help you get in control for you to be comfortable enough to move from that feeling of DREAD to CONFIDENT; and making an awesome Impression for that great rating your supervisors should be giving to you so freely.

Consider these tips as you prepare for your defence. We will be taking them one after the other so here we go.


Watch Your Body Language And Keep It Confident:

Can you tell that a person is falling apart if they look confident? … If I can second guess you rightly, am sure you answered no to that question. Remind yourself that you need to come out that way. Now this might seem like a huge big deal when you are dealing with the foreboding. Maintaining a poise of confidence is very important. So find your most comfortable position, sitting or standing and draw up your body. You must exude confidence. It is something you need to do for yourself. People can only see what you allow your body language to show. So you must endeavour to put that out. Remember the story of David and Goliath? … At the end of your defence day, you want to be David.


Dress In Your Most Comfortable And Impressive:

Am sure this one is a no brainer. However I must highlight that you choose comfortable pieces. You don’t want to look so good and yet look like you were forced to wear something that does not belong to you. It’s great to ensure that as impressive as your clothes are on you, that they are also very comfortable.


Speak With Authority:

Going hand to hand with that aura of confidence is your most powerful asset:your words. If you look that confident, your words must not come out like whimpers. To be able to pull this off, you definitely need to speak as deliberately as possible in expressing yourself. Let them also hear what they see.


Use, Your Gestures:

I have often found this to come to my rescue in dealing with shyness and conveying my confidence. Usually it gives you an edge to also drive home your point. You must, however, ensure that you do not over use it. It doesn’t mean that your hands should be flying all over the place. That would be absolutely unnecessary. If you do this well, after a while you will realize that you are not as self-conscious as you used to be at the very start. For most situations, it would have completely disappeared altogether; leaving a really confident you talking.


Have A Good Opening And Closing Line:

Make sure you have perfected a good opening line. You should also be armed with a good closing line too. Try and rehearse it to a friend. If for the first time you presented it, your friend does not say “wow, that’s beautiful” or something like that; just know you need to keep refining it until you get the perfect line. Both opening and closing lines will go a long way in how impressed your panel gets to rate you high.


Make Sure You Know Your Work:

Certainly you should understand how important it is to know your own work from start to finish. Not having in-depth knowledge of your own work is tantamount to a suicide mission. Why should you kill yourself?
When all is said and done, this is what you came to defend in the first place. You should know your work from A to Z.


Prepare For The Questions:

Now this part is truly essential. You must be sure you do not floor all the good work you did on your presentation by not answering correctly. You must pay attention to the questions you are asked to be sure you will give the right answer. Many people get it wrong at this stage and spoil their good presentation. When you do not understand any question do endeavour to ask the person to expatiate what they mean before you answer.


These tips are by no means exhaustive, but applying these tips will give you some necessary advantage you need for a great outcome. Of course that outcome would mean that you eventually earn all your points on this project.
