Abstract

With the fast innovation and transformation that happen in our lives, security systems play an essential role in guaranteeing our safety and have become important part of protecting assets, houses, and campuses. The potential for theft and intrusions is increasing every day, making efficient access control for visitors coming in and out of facilities more critical. This paper focuses on developing an accurate access control system for special campus entrance doors with sensitive missions. The proposed system controls the entry of individuals to the campus by permitting authorized persons to enter while denying unauthenticated persons and notifying security guards via the GSM network.The system mainly consists of two Arduino microcontrollers connected to sensors that control security. Network facilities (GSM and Wi-Fi) as well as Internet services (website and Telegram bot) are integrated into the system to exchange information and save visitor information within the system. Arduino boards serve as activity centers to receive visitors' input (fingerprint codes, photos from cameras, position data from ultrasonic sensors), which are then analyzed and processed to accept or reject visitors. Finally, the system sends output to connected servers (Telegram bot, MySQL database, webserver). After testing the proposed system many times, results indicate that better authentication performance can be achieved with average time of only 8 seconds. The multi-channel communication used by this system makes it far more capable than others do while also improving security through two-factor authentication to verify a visitor's identity. However, one of the aforementioned channels requires 24/7 Internet services.
