Access Control System : An access control system is a security solution designed to regulate and monitor entry to physical or digital spaces. It ensures that only authorized individuals can access specific areas, devices, or information by using methods such as keycards, biometric scans, PIN codes, or mobile apps. Advanced systems integrate with surveillance and alarm systems for enhanced security. Commonly used in offices, schools, and restricted facilities, access control systems improve safety, streamline entry processes, and provide detailed access logs for monitoring and audits.
