The typical sensors, which are usually two magnets, are generally installed on doors and windows such that one magnet is connected to the door or window and the other is connected to the door or window frame. When the door or window is opened, one magnet is removed from the surrounding area of the other and the sensor registers that the door has been opened. More advanced home alarm systems may also contain vibration sensors to detect when glass has been broken by measuring the vibrations caused by the breakage. Also, many systems use motion sensors that compute the proximity of a room’s walls by producing infrared beams and measuring the time required for them to bounce back; if a beam comes back sooner than expected, it likely bounced off of a person and the sensor registers motion. The control center keeps track of the status of the sensors and reports activity through LCD displays and other output devices. 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.
In the words of BSA 2013, "the scorecard examines major laws and regulations relevant to cloud computing in seven policy categories as well as each country's ICT related infrastructure and broadband deployment. " Some of the factors that carry significant weight in the said scoring system therefore include but they are not limited to cloud computing rules international harmonization, presence of effective anti cyber crime penalties, intellectual property…… Security Sector eformOverview of the relevant arguments regarding Security Sector reformThe objective of security sector reform has to take care of the threats to the security of the state and the safety of its citizens. These arise often from the situation within the state and military responses may not be suitable. This leads on to an analysis of the government. The second article talks in a wider, more theoretical and less action oriented tone. It says that "existing constitutional frameworks have been used to maintain status quo than promote change.
