This project consists of an intelligent access control system using a Raspberry Pi and a camera that automatically detects the presence of a person. When a person is detected in front of the camera using an AI powered camera system, the system prompts the user to enter a PIN code via a keyboard. The user has 10 seconds to input the correct access code. If the code is valid, access is granted; otherwise, the system triggers an alarm, such as a buzzer or LED light, and sends a message via MQTT indicating unauthorized access.
From a sustainability perspective, this project contributes to both sustainability and security by promoting energy-efficient and intelligent access control solutions. By only activating the system when a person is detected, it reduces unnecessary power consumption and avoids continuous monitoring or manual intervention. Additionally, it enhances home and facility security through an automated verification process, minimizing the risk of unauthorized access.
