safety alarms for elderly Chapter II:Our Home Alarm SystemOur Home Alarm System:Our project’s main concern was to build a Home Alarm System using a PIC microcontroller. We started off our project by coding the Keypad, then LCD and the final touch was the sensor. We also added two types of buzzers: one to sound the alarm and the other as a key tone buzzer. The final result turned out to be the following:Figure3. Our Home Alarm SystemMaterials Used: Cost:PIC16F877A 7$4X4 Keypad 2$JHD 162A LCD 6$6V Alarm Buzzer 0. 5$Key tone Buzzer 0.

Such dynamics has seen the rise of private security in the U. S. And globally Lyon, 2005. Perhaps, the increase in terror threats has made many governments and individual to procure the services of private security firms because of the in surveillance and undercover operations. This study has focused on St. Moritz Security Services based in Pittsburg, Securitas Security Services based in Chicago, and Allied Barton Security Services based in Pennsylvania.
