The innovations demanded by community and problem oriented policing require that departments incorporate a geographic, spatial, or local focus, and emphasize the importance of integrating crime mapping techniques into departmental management, analysis, and enforcement practices. " 2006 What is needed, according to the work of Kehoe is 'standardization' insofar as the technology used in law enforcement and private security so as to enable more integration and coordination between the two entities. The tools which Kehoe includes in the foregoing list are not an exhaustive list whatsoever. The work of Ashley Paul Moore entitled: "First Responder Accreditation: The Pros and the Cons" states that there has been a debate among members of Congress as to whether there is…… SecurityPrivate Security vs. Law Enforcement: Matrix Summary"Private security and public law enforcement share many of the same goals: preventing crime and disorder, identifying criminals, and ensuring the security of people and property," "Private Security and Public Law Enforcement," n. d. There are many more private security officers than public police officers, making tandem projects and collaboration essential "Private Security and Public Law Enforcement," n. d. There may be some overlap between public law enforcement and private security, but generally the latter can be more highly specialized and are therefore useful in situations such as campus security.

Dual Tech motion detectors use two different technologies in the same unit: passive infrared and microwave. These devices are designed to avoid false alarms since both technologies must detect motion before setting off the alarm. Photoelectric Sensors: These sensors project a beam of light across a hall or doorway to detect motion and are triggered when a person passing through interrupts the beam. Glass Break Detectors: Usually mounted near windows to detect the specific high frequency sound of glass being shattered. They are usually installed on a wall opposite or adjacent to the protected glass and are effective within about 15′ to 25′. Smoke and Heat Detectors: Detect smoke and heat. 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.
