Access control systems are essential technologies for managing and regulating access to physical and digital resources. With the goal of ensuring that only authorized individuals have access to resources, these systems use user credentials, such as passwords, smart cards, or biometric data, to verify the identity of users and grant or deny access. But what exactly are access control systems, who created them, and how do they work? This article will explore the basics of access control systems, including their history, functionality, and safety.

History of Access Control Systems

Access control systems have a rich history, dating back to ancient times when locks and keys were used to control access to buildings and rooms. However, it was not until the development of modern electronic means of authentication that the concept of access control systems as we know it today was born. Today, numerous individuals and organizations continue to improve and refine access control systems.

How Access Control Systems Work

Access control systems work by verifying the identity of individuals and granting or denying access to resources based on predefined rules. The process includes four main steps: identification, authentication, authorization, and access granting or denial. The system identifies the user by verifying their credentials, such as a password or ID card. Once the user’s identity is verified, the system checks if they are authorized to access the resource in question. If so, the user is granted access. If not, access is denied and the system may provide a reason for the denial. Access control systems also monitor and log all access attempts, including the outcome, date and time, and identity of the user.

Leading Companies in Access Control Systems

There are many companies that create access control systems, including HID Global, Bosch Security Systems, Assa Abloy, and Johnson Controls, among others. These companies offer a wide range of access control solutions, serving industries such as commercial, industrial, healthcare, education, and government.

Installing Access Control Systems

Access control systems can be installed by professionals with specialized knowledge and experience in the field, including security systems integrators, locksmiths, electricians, and IT technicians. For complex or large-scale systems, it is recommended to use the services of a professional systems integrator. The manufacturer or supplier of the access control system may also offer installation services. It is important to choose a qualified and experienced professional for installation to ensure the system is properly installed and configured.

Are Access Control Systems Safe?

Access control systems are generally considered safe, as they are designed to enhance security and protect against unauthorized access. However, they can be vulnerable to certain risks and threats, such as hacking, tampering, or technical failures. To ensure the safety and reliability of an access control system, it is important to follow best practices for design, installation, and maintenance, including using secure authentication methods, regularly updating software and firmware, and implementing physical security measures. Regular security assessments and addressing vulnerabilities can also help ensure the system’s safety and reliability.

Risks Involved with Access Control Systems

Access control systems are not immune to risks and threats. Some of the common risks involved include hacking, technical failures, and unauthorized access. It is important to stay informed and proactive in addressing potential risks and to follow best practices for design, installation, and maintenance to ensure the safety and reliability of the system.


Access control systems are essential technologies for managing and regulating access to physical and digital resources. With a rich history and continued advancements, these systems offer a high level of security and safety when properly designed, installed, and maintained.
