Intrusion Detection for Smart Home Alarm Security System

Smart home security is increasingly essential in today’s world due to rising concernsover unauthorized access and property intrusion. Leveraging the capabilities of Raspberry Pi, a lowcost and efficient home security system is developed that combines motion detection, real-timeimage capture, SMS and email alerts, and automated door locking. The system uses OpenCV formotion tracking, a GSM module for text notifications, and a buzzer for local alarms, all integratedthrough Python scripts. A voltage regulator and backup battery ensure uninterrupted functionalityduring power outages. Testing showed over 90% accuracy in intrusion detection and prompt alertdelivery within seconds. The solution is both scalable and affordable, bridging the gap betweenhigh-cost commercial systems and the growing need for smart, userfriendly home protection. Futureimprovements include AIbased facial recognition, cloud storage, mobile app integration, andsupport for multiple surveillance nodes.
