Access Control Systems

Access control systems are technological security systems used to control and secure the entry and exit of individuals to a physical location, preventing unauthorized entry or access. The locations where access control systems can be implemented are quite diverse. For example, these types of security applications are commonly used in public institutions such as airports, courts, police stations, ministries, offices, hotels and resorts, hospitals, and banks. In short, an access control system facilitates the entry and exit of authorized individuals, prevents unauthorized persons from passing, and increases the security level of a space or area.

Access control systems aim to control entries and exits to a space or area:

Access Control: Access control systems allow only authorized persons to enter protected areas. For example, it provides unlimited access to all employees of a company for a designated area or limited access to a specific group or department. This prevents the entry of unauthorized persons and ensures security.

Identity Verification: Access control systems use various recognition methods to authenticate individuals. Through methods such as fingerprint, face, iris, or card recognition, the identity of the person passing through is verified, allowing or preventing access.

Record Keeping and Monitoring: Access control systems keep records of individuals passing through and allow monitoring. This enables accessible and reviewable information such as “who passed through when and from where.” Event records can be used for security reviews, time management, or employee tracking purposes.

Increasing Security Level: Access control systems enhance security by preventing unauthorized access. Unauthorized entry attempts can be detected and trigger an alarm when desired, providing high-level protection against theft, attacks, or other security breaches.

Time and Resource Management: Access control systems can be used to track employees’ working hours and ensure efficient use of resources. For example, access to a specific area may only be granted at certain hours, or specific resources may be allocated to certain departments or users.

In summary, access control systems ensure security, control access, and support the efficient use of resources in many sectors.

The access control systems detailed below provide security and prevent unauthorized access. Each recognition method has different advantages and can be preferred singly or in combination depending on usage scenarios.

Fingerprint Recognition: Fingerprint recognition allows identity verification by using individuals’ fingerprints. Fingerprints are unique and have unique patterns. Fingerprint scanners capture the fingerprint using optical or capacitive sensors and analyze this data to perform identity verification. Fingerprint recognition provides high accuracy in terms of security and minimizes the risk of fraud.

Card Access: Card access control systems provide access through individually assigned cards or smart cards. Cards use data storage methods such as magnetic stripes, barcodes, or radio frequency technology (RFID). The user performs identity verification by touching or approaching the card to a reader at the access point. Card access systems provide a practical and fast access method, making it easy for many users to use the same system.

Face Recognition: Face recognition technology verifies identity by using individuals’ facial features. Face recognition systems use cameras and special algorithms to analyze the geometric, textureless, and unique features of the face. Based on patterns, lines, and ratios of the face, identity verification is performed. Face recognition provides quick and effective identity verification, requires no physical contact from the user, and can be used on a large scale.

Iris Recognition: Iris recognition allows identity verification by using individuals’ eye irises. The iris is the colored part of the eye and has unique patterns. Iris recognition systems scan eye irises using special cameras and analyze these patterns. Identity verification is performed using the vein structure, patterns, and combinations of colors of the iris. Iris recognition provides high-security levels and is not affected by glasses, lenses, or changes in lighting.

QR Code Reading: QR Door Access Systems are advanced technologies that perform passage and control operations using the QR code recognition application, one of the contemporary technologies. This system provides secure access and monitoring solutions for institutions, offices, facilities, or other locations. The QR Door Access System operates with a QR code scanner placed next to the door. This scanner reads the QR code owned by the user to initiate the verification process. The QR code can be on the user’s smartphone or on a card. The user obtains passage permission by showing or scanning the QR code to the scanner.

After the scanner reads the QR code, it compares it with the authorization database stored in the system. This database may contain information such as the user’s access permissions, passage times, or access control to specific areas. When the validity and authorization of the QR code are confirmed, the door automatically opens, granting passage permission to the user. This system provides a user-friendly experience and can be easily integrated. Additionally, the quick scanning of the QR code enables fast passages and reduces unnecessary waiting times. QR Door Access Systems eliminate the use of physical keys or cards, reducing the risk of security vulnerabilities and enhancing security.

However, QR Door Access Systems also have additional functions such as keeping and monitoring passage records. Data related to scanned QR codes at access points is recorded, and this data can be used for security reviews, employee tracking, time management, and reporting purposes.

Access control systems are used to control entries to a space or area and prevent unauthorized access, increasing the level of security. Each recognition method provides a unique identity verification feature and minimizes the risk of fraud.

These systems also provide users with quick and easy access. Methods such as fingerprint recognition, card access, face recognition, iris recognition, or QR code recognition allow users to use their biometric data (fingerprint, face, iris) or QR codes instead of carrying physical keys or cards. This enables users to pass more conveniently and quickly.

Access control systems keep records of individuals passing through and offer monitoring capabilities. These records include information such as passage logs, authentication dates, and times. With monitoring and reporting features, functions such as security reviews, employee tracking, time management, and reporting can be performed.

Access control systems provide flexibility and scalability for different spaces and organizations. These systems can be implemented in various sizes, from small offices to large businesses or complex facilities. Moreover, systems are often modular and can be expanded to meet current requirements and growth needs.

A access control system also assists in time management and effective use of resources. For example, it can restrict access hours to specific areas or allow access to certain resources only for authorized users. This serves as a valuable tool to track employee movements, optimize business processes, and control resource usage.
