Design And Construction Of A Smart Burglar Alarm
The design and construction of a smart burglar alarm entail the creation of a sophisticated security system that integrates advanced technology to detect and deter unauthorized intrusion into a property. This system typically incorporates various components such as sensors, cameras, and control units, all interconnected through a network to enable real-time monitoring and remote access. The sensors, including motion detectors, door/window sensors, and glass break detectors, serve to detect any unusual activity within the premises, triggering the alarm system to alert homeowners or security personnel via notifications on their smartphones or other connected devices. Additionally, smart features like integration with home automation platforms enable users to remotely arm/disarm the alarm, receive live video feeds, and even communicate with visitors via two-way audio. The construction of such a system requires careful consideration of both hardware and software components, ensuring seamless integration, reliability, and user-friendly operation while addressing the specific security needs of the environment in which it is deployed.
ABSTRACT
Burglary is an unwanted event that no one wants it to happen their premises. However it is difficult for anyone to be alert at all the times to protect their premises. This device Smart Burglar Alarm helps in this situation by raising an Alarm when there is an unwanted intrusion in the secured premises.
The Smart Burglar Alarm is based on a loop of copper wire which is laid at the entrance of the secured area. When an intruder steps in breaking the loop, the system activates an alarm connected to the system. By hearing the alarm the resident of the office / home can get alert about the intrusion and a possible burglary. The alarm sounds till the system is turned OFF or the wire loop is connected back.
The principle of working of the project lies in the conductivity of a long copper wire which switches a transistor in its absence. In presence of the copper wire loop the system switches the transistor in way that the alarm is switched off. On the contrary, when the copper wire is cut off the transistor switch is complimented thus switching ON the alarm. Thus the user gets notified of an intrusion.

CHAPTER ONE
1.1 INTRODUCTION
The need for having home protection has always been there. But in the recent times, considering a dramatic rise in petty crimes like robbery and theft, the need has been more strongly felt to have a fool proof protection of the belongings and the family members. Home security has come a long way in the last few decades. It was in the hands of a guard who manually provided surveillance during nights in the earlier days, but it was not fool proof as it was only normal for him to have momentary lapse of concentration.
The guard was also susceptible to sleep at times. It was then that home alarm system based upon electronic circuits were developed which proved to be highly reliable and were appreciated by the people as they were relieved from constant monitoring of their homes.
This burglary alarm system uses IC which was wired as a timing circuit, as tone generator and amplifier to obtain a maximum audible sound. The ic times the circuits and also generates a tone and this tone is send to transistor which amplifies the tone generated through a loud speaker or buzzer.
The reset button is used to reset or open circuit the system back to its initial stage. The system is powered with 12V power supply voltage.
1.2 AIM AND OBJECTIVE
The main aim and objective of the design and construction this project is to create a comfort in the minds of house owners when they out from their premises without much fear of intruder.
1.3 SIGNIFICANCE OF THE PROJECT
This device functions as an electronics watch dog. This device functions as a major security alarms used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders.
1.4 APPLICATION OF THE PROJECT
Burgular alarms are used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders. Car alarms likewise protect vehicles and their contents. Prisons also use security systems for control of inmates.
1.5 SCOPE OF THE PROJECT
This circuit will help you to guard your precious documents as well as jewellery from intruders or theft. All you need is just to place this circuit in front of the locker or below the mat so when any unknown person come and walk over the switch, the circuit will trigger and sound of alarm comes. The main benefit of the circuit is that these can be implied in two places at a time as two different switches produces two different sounds.
1.6 LIMITATION OF THE PROJECT
Can Be Expensive:
High quality, state-of-the-art alarm systems don’t come cheap. They require substantial initial investment, which includes equipment cost, installation and subscription of security monitoring service.
False Alarm:
Most systems are prone to false alarms that involve the alarm going off on you, or the alarm sounding off even when there’s no emergency situation. This can be extremely embarrassing, especially when the alarm sound sounds and the authorities – show, only to find that you tried to “break” your own house.
1.7 PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
Chapter one of this works is on the introduction to a burgular alarm. In this chapter, the background, significance, objective limitation and problem of a burgular alarm were discussed.
Chapter two is on literature review of a burgular alarm. In this chapter, all the literature pertaining to this work was reviewed.
Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed.
Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
Chapter five is on conclusion, recommendation and references.
