The rapid rise in thefts and break-ins across the globe has become a significant concern for homeowners and businesses alike.Traditional security systems often fail to offer real-time surveillance and immediate action, especially when authorities are unable to respond swiftly.As a result, there is an increasing demand for smarter, more responsive security solutions.In this paper, we propose a Smart Door Lock Security System that leverages the capabilities of the Internet of Things (IoT) and Raspberry Pi to enhance the security of residential and commercial properties.This system integrates a motion sensor, webcam, and email alerts to ensure immediate notification and action when a potential security breach occurs.The proposed system is built around the versatile Raspberry Pi, a small, affordable computer that can perform a variety of functions.Raspberry Pi serves as the central hub of the system, controlling the motion sensor, webcam, and email notifications.The main objective is to detect intruders in real-time and notify the property owner about suspicious activity, such as unauthorized entry or tampering with the door lock.Raspberry Pi The heart of the system, responsible for processing inputs from the motion sensor and webcam, and triggering actions such as sending emails.Motion Sensor A passive infrared (PIR) sensor is used to detect motion in the vicinity of the door.When a person This system can be further enhanced by incorporating advanced features such as facial recognition, biometric sensors, and cloud storage for long-term video surveillance.With its low cost, ease of use, and scalability, this system presents a promising alternative to traditional security solutions, ensuring better protection against theft and other security threats.
