With the help of the latest development of technology, it is possible to secure people’s lives, industries, schools, organizations, and homes using an alarm security system that will monitor, guide and protect against burglar and abductors, because of the rate of theft and abduction in some parts of the world is increasing by the day; this imbibes fears that become a threat to the peace and economic development of any society or country nowadays. It is paramount to find viable technologies that will secure the lives of humans as countermeasures to tackle this kind of problem. This paper will review literature related to security alarm systems, different types of sensors used in the security system, advances in its technology, and disadvantages of installing the security alarm system and the importance of installation for security purposes in which most of the papers I read did not. KEYWORDS: Abduction, Alarm System, Burglar, Security, and Sensors. 1. INTRODUCTION The security alarm system likewise offers a great means for supporting and helping different needs of folks that have disabilities precisely old age people or individuals with a certain illness that will not allow them to be moving around either in offices, organizations or homes.

One of the motives for this is the increase in crimes, abduction, and robbery in the world today. Many of our homes, industries, schools, and organizations today are invade mostly by force either through a criminal entry or through 50 International Journal of New Computer Architectures and their Applications (IJNCAA) 9(2): 50-59 The Society of Digital Information and Wireless Communications, 2019 ISSN 2220-9085 (Online); ISSN 2412-3587 (Print)
