Door access control is a security system designed to permit authorized personnel to enter a building or restricted area while locking unauthorized individuals out. These doors are equipped with electronic access control system that requires users to present a valid credential, such as a key card or a code, to unlock the door. Moreover, it can track who enters and exits the premises, providing valuable security data.
Door access control system is widely used in various settings, from office buildings and schools to residential complexes and gated communities. It delivers a higher level of security compared to traditional locks and keys, helping to deter crime and unauthorized entry. When combined with other security methods, such as CCTV and alarms, door access control systems can significantly enhance the security of any environment.
Types of Door Access Control Systems
Mandatory Access Control (MAC)
Mandatory Access Control (MAC) is one of the best secure types of access control. It is commonly used by the military and other government agencies. In a MAC system, users cannot change their permissions to permit or deny access to specific areas. Instead, a system administrator configures the settings, deciding which users have access to which doors.
Role-Based Access Control (RBAC)
Role-Based Access Control (RBAC) is a security model that provides permissions to users based on their roles within an organization. This model restricts access to systems, applications, and data according to each user’s role. RBAC is typically established using a combination of software and hardware controls, ensuring that only authorized users can access specific systems and applications.
Discretionary Access Control (DAC)
Discretionary Access Control (DAC) is a popular choice for many businesses. DAC allows business owners to control which employees have access to certain areas within a facility. Any entry point has an Access Control List (ACL) that specifies which groups or individual employees are allowed to enter.
Rule-Based Access Control
Rule-Based Access Control is a type of DAC that incorporates elements of RBAC. In this method, each user is granted a set of roles, and each role is permitted to perform particular actions. For example, a user in the HR department might have both “employee” and “manager” roles. The “employee” role would allow access to general employee areas, while the “manager” role would grant access to both employee and manager areas.
Benefits and Drawbacks of Discretionary Access Control
Benefits of DAC
- Flexibility: Businesses can easily reorganize or remove users from groups and adjust which groups have access to specific areas, making it adaptable to changing needs.
- Simplicity: DAC is often simpler to implement compared to other access control methods like RBAC.
Drawbacks of DAC
- Management Complexity: In large or complex organizations, it can be challenging to manage access for numerous groups and areas.
- Lack of Separation of Duties (SoD): DAC does not inherently enforce SoD, which can result in users having too much control over sensitive data.
Mechatronic Access Control
Mechatronic access control involves using electronic or electromechanical gadgets to authorize access to a facility or private area. This type of control system is gaining popularity due to its reliability and flexibility. A mechatronic access control system typically includes a controller, readers, and locks. The controller manages access requests and communicates with other system components. Readers identify authorized users and grant access, while locks physically prevent unauthorized entry.
Mechatronic access control systems can be installed in various applications, including residential, commercial, and industrial settings. In residential areas, these systems are often found in home security setups and gated communities.
Biometric Door Access Control System
Biometric door access control system uses biological characteristics or behavioral characteristics to identify authorized users. Common biometric traits include fingerprints, iris patterns, and hand geometry.
Biometric systems are more dependable than traditional access control methods because they are harder to bypass. Additionally, they provide a higher level of accountability by tracking who accessed a secured area and when.
Conclusion
Door access control system is essential for maintaining security in various environments, from residential homes to large government facilities. Understanding the different types of access control—MAC, RBAC, DAC, and mechatronic and biometric systems—can help you choose the best solution for your needs.
Each type has its benefits and drawbacks, but all aim to ensure that only authorized individuals can access specific areas, thereby enhancing overall security. Whether you need a simple system for a small business or a robust setup for a high-security facility, there is an access control system that can meet your requirements.

FAQs
Do I Require Special Expertise to Install Access Control?
Yes, installing an access control system requires specialized knowledge of low-voltage wiring, networking, electrical codes, and physical security best practices. It is advisable to hire experienced access control technicians to ensure proper deployment and avoid ineffective security measures.
What Tools Should I Have on Hand For Access Installation?
Essential tools for installing access control systems include levels, measuring tape, screwdrivers, wire strippers, crimpers, zip ties, and a cable tester. Depending on the specific control panels or door hardware, additional specialized tools may also be required.
How Disruptive is Installing Access Control?
Professional installers strive to minimize disruption by working cleanly and controlling dust and debris. However, running wiring inside walls or above drop ceilings may necessitate temporarily moving furniture and making minor drywall or masonry repairs afterward.
How Long Does a Typical Access Control Installation Take?
The duration of an access control installation varies based on the system’s scale and site-specific challenges. Generally, installations take 1-2 weeks. Larger projects with custom wiring can take over a month. Evaluating the complexity beforehand helps in setting realistic expectations.
