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. Moreover, as a justification for this reasoning is the fact that it is required to scan the columns for the pressed key and then scan the rows and the results will be decoded in a decoder telling us which button of the keypad was pressed. The main functionality of the keypad as mentioned earlier is to set the code. The alarm can be armed and disarmed with a standard four digit user code in our case.

Surveillance devices are often hidden in walls or ceilings, so look for any spots that appear to be spackled or recently concealed. However, with the decreasing size of surveillance equipment, illegal surveillance can be concealed virtually anywhere. Household objects such as pens, clocks, lamps and even watches may contain devices to see and hear what you are doing. Closely examine your home's windows, as the exterior of windows are excellent places for installing illegal surveillance devices since no one has to break into your home to install them. Conduct “sweeps” of your home on a regular basis. Keep an eye out for any signs of a break in as well as any strangers that come inside or even near your home. A phony meter reader or telephone repairmen is an old trick, but that doesn’t mean an estranged spouse or business partner wouldn't also try to insert illegal surveillance in your home. Also, securing the perimeter of your home prevents someone from installing surveillance equipment at the outset. Consider purchasing a home security system to prevent break ins, deter unsavory characters from your property and monitor the whereabouts of individuals you do allow into your private space. Private security is a business that isn’t limited to just providing armed security personnel it also includes selling security devices for homes and offices. The private security business also installs complete home security automation, conducts private investigations, screens prospective employees, and provides security consultation to corporations.
