security systems house Initially, security was begotten from the need to protect important personages who, not infrequently, were in the private sector. Therefore, the history of security can be traced to the private security guards who were appointed to protect the Pharaohs and the rulers in Egypt. It is worth noting that these security personnel worked for those in the public sector, yet were themselves comprised of individuals from the private sector. In general, this trend would continue to this very day, in which there are currently private security companies engaged in services in which they are combating forces of ISIS for the public sector. Perhaps the most notable security advancements to initialize within Westernization are found in the history of ancient Rome. The Vigiles Urbani was…… Physical SecurityThe relevance of physical security cannot be overstated when it comes to the prevention or minimization of instances of unauthorized access, loss, or even theft. In this text, I concern myself with physical security and the relevance of several of its components. The components I will address in this discussion are building security, grounds security, access control systems, perimeter security, and information systems and technology security. Physical Security: Brief OverviewIn the assessment of security vulnerabilities, physical security is generally regarded a critical issue. This is particularly the case given that it is the said physical security that presents the most serious obstacle to an attacker seeking to execute a break in. In that regard therefore, the various components of physical security, some of which are discussed in significant detail in this text, should seek to secure people and organizational assets from intruders.

Moreover, when activity takes places, such as the opening of a window, the sensors report the activity to the control center and the center registers that a disturbance has occurred. In managed alarm systems, the control panel also checks the sensors to verify that they are still operational; if a sensor fails to reply, the center alerts the home owner of an out of order sensor. If the home owner activates the alarm system and the control center registers activity in the home, a signal is sent by the control to a buzzer, flashing lights or any other audiovisual alarm element. Our design for a functional keypad was the usage of an alternation of ports between inputs and outputs which is done by using the TRIS function. We started off by setting the first four ports of PORTB as the inputs and the latter four ports as the outputs. The first four ports are connected to the columns meanwhile the last four are connected to the rows.

One of these ways is accurate data collection, data presentation, and collection of other relevant statistics.
