Security Management and Safeguard of properties have become a necessity in any establishment and requires a measure to deny access to unauthorized personnel from accessing a facility. Some of these measures come at a cost as security is inevitable. The objective of this project was to design and implement an affordable, effective and reliable wireless intruder detection system and to minimize false triggering and enhance detection using Dual Infrared Technology. The idea was to employ distance infrared proximity sensor (SHARP 0A41SK) which generated an interrupted signal when any obstacle is in front of IR sensor. The interrupted signal was fed to an IC (NE 555) timer arrangement to produce a flip-flop audible sound to alert people of intruder presence. The designed and constructed dual infrared intruder detection system subjected to testing produced an accurate security zone that spreads out uniformly to enhance protection for properties, homes and offices. The system could be adapted to monitor other alarm conditions such as fire, heat smoke, flood, etc. The design could be recommended for use of GSM applications as the alarm system that could be programmed to call Police distress line directly and relay a pre-programmed message with the address of the intrusion scene for better response rescue by the police.
