PI GUARD ENHANCED DOOR SECURITY WITH RASPBERRY PI

Abstract—There has been a rapid rise in cases of theft; this requires urgent security measures against these crimes. Thieves should be apprehended early and effectively. Here comes a door security system proposed based on Raspberry Pi to handle such matters. It comprises a keypad to provide password authentication, the Pi Camera to take snaps in case of three failures, and a buzzer that is used for sound warnings. In the case of three wrong password attempts, the system captures an intruder’s picture and delivers them via email to the resident along with the nearest police station with the help of SMTP. The buzzer rings out with every incorrect attempt. A solenoid or stepper motor acts as a lock for physical security. This system combines affordability, scalability, and efficiency in enhancing responsiveness and deterrence during unauthorized access at- tempts, providing a practical and modern solution for residential security.
