The project aims in designing a “Face Recognition Door Lock System Using Raspberry-Pi” Smart Receptionist with smart lock system is mainly designed and developed for security systems. This smart security system is used to see a visitor when the main door of the office or Home is closed. Today we face security issues in each angle. So we attempt to determine these issues by utilizing refreshed innovation. During this task, we are utilizing the Face acknowledgment module to catch human pictures and saving in a data base. Assuming it Image matches with the data base then door will be opened by an electromagnetic lock with help of lock. The use of face recognition system that's accurately detect all unauthorized users from highly secured areas and aids in minimizing human error. Face recognition system is one of the highest security system when compared with finger print locking system and also password based security system. The time and accuracy factor is taken into account about the main problem which specifies the performance of automatic face recognition in real-time environments. If you're within the middle of a meeting in a conference room and there's a visitor at the door, this technique will send a notification to your smartphone with a photograph of the visitor as email. Security is one of the most critical concerns in both residential and commercial spaces. Traditional security systems, such as manual locks and password-based systems, pose risks due to unauthorized access and password leaks. The Smart Door Receptionist with Smart Lock System integrates face recognition, IoT, and Raspberry Pi-based automation to enhance security and streamline access control. The system employs a Pi camera, Raspberry Pi 4, solenoid lock, and relay module to authenticate visitors using facial recognition. If the visitor is recognized, the door unlocks automatically; otherwise, an alert is sent to the homeowner's smartphone for manual approval.
