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.

Clearly, the private security industry, and all security, was impacted by the September 11 terrorist attacks in New York, Washington D. C. And Pennsylvania. Airport and border securities were tightened, and many Americans turned to private security firms to ensure their own personal safety. Millions of businesses also turned to private security to shore up their business defenses. Studies indicate that some forms of private security services are booming, but overall, the security industry has actually declined between 1999 and 2004. The nation's private security industry has certainly changed since the September 11 terrorist attacks, but how much it has changed really depends on specific areas of security.
