How to Choose the Right Access Control System for Your Building
Selecting the right access control system is an important decision for building managers, business owners, and strata professionals. A suitable system not only keeps occupants and valuable assets safe but also supports efficient day-to-day operations.
With a range of systems available—from biometric readers to mobile-enabled access—understanding the strengths of each option helps you choose the best fit for your needs. This guide covers system types, key features, budget considerations, compliance, and how to choose a reliable provider—helping you make a long-term, informed decision.
Understanding the Different Types of Access Control Systems
Here’s a breakdown of common access control types and where they work best:
Discretionary Access Control (DAC)
DAC systems allow data owners or administrators to control who can access specific areas or resources. These are common in coworking spaces and small offices where users need flexible control. However, they’re not ideal for high-security environments, as permissions can be changed or bypassed easily.
Mandatory Access Control (MAC)
MAC systems operate under strict classifications, typically used in government or high-security sectors. Permissions are assigned based on security clearance, and users cannot change their own access rights. While highly secure, MAC systems are usually too rigid for commercial environments that require flexibility.
Role-Based Access Control (RBAC)
RBAC assigns access based on roles within an organisation—such as manager, staff, or contractor. This structure streamlines onboarding, simplifies permission changes, and enhances security in places like corporate offices, hospitals, and universities.
Biometric Access Control
Biometric systems use identifiers like fingerprints, facial recognition, or voice. They eliminate issues with lost cards and provide a high level of security. While widely used in data centres and labs, they’re becoming more common in commercial and residential buildings due to their ease of use and accuracy.
Key Card, FOB, and Mobile Access
These RFID-based systems are cost-effective, easy to manage, and popular for businesses of all sizes. They also integrate well with CCTV and alarms for enhanced control and centralised monitoring.
Factors to Consider When Choosing an Access Control System
Building Layout and User Volume
Your building’s function determines the ideal setup. Commercial offices may need flexible access times and remote management, while residential complexes prioritise ease of use. Larger sites benefit from cloud-based systems that scale easily.
Number of Users and Entry Points
A building with high foot traffic and multiple access points requires a system that allows user grouping, time-based access, and detailed reporting. Scalable systems make it easier to adapt as the building or user base grows.
Integration with Existing Systems
The access control system should integrate with current CCTV, alarms, and fire safety systems. Integration improves overall security, centralises monitoring, and streamlines incident response.
Industry Regulations and Compliance
Ensure your system supports features like audit trails, user logs, and data encryption. Compliance with data privacy and safety codes protects your business legally and builds trust with stakeholders.
Environmental & Operational Conditions
Outdoor systems need weather-resistant hardware. In high-traffic or public areas, choose vandal-resistant devices. Consider 24/7 access needs and emergency egress to ensure the system remains reliable under all circumstances.
Why User Needs and Convenience Matter in Access Control Systems
User-friendly systems increase compliance, reduce operational disruptions, and improve overall security effectiveness.
Balancing Security with Ease of Use
Complex systems can frustrate users and lead to workarounds. An intuitive interface with reliable performance promotes consistent usage and better security outcomes.
Streamlining Access for Regular Users
Sites with frequent staff, tenants, or visitors benefit from features like scheduled access, mobile control, and auto-unlocking doors. These reduce manual intervention and improve efficiency.
Emergency Accessibility
Administrators should be able to override locks when needed. Ensure your system includes backup power, fail-safes, and remote override options for emergencies.
What Security Features Should You Look For?
Audit Trails and User Logs
Complete records of who entered and exited provide transparency, accountability, and support for investigations.
Multi-Factor Authentication (MFA)
Combining PINs, swipe cards, and biometrics adds layers of protection—ideal for environments handling sensitive data or assets.
Remote Access and Real-Time Alerts
Web-based dashboards and mobile apps allow off-site management, including modifying user permissions and receiving alerts.
End-to-End Encryption
Protect data with encrypted communication between devices and management platforms, reducing vulnerability to cyberattacks.

How to Assess the Scalability of Access Control Systems
Growth-Friendly Infrastructure
Your system should scale with your organisation—accommodating new locations, users, and access rules without costly overhauls.
Multi-Site Management
A centralised platform allows control over multiple locations, maintaining consistency and simplifying administration.
Software Updates and Compatibility
Make sure the provider is providing timely software updates to improve functionality and close security gaps. The system should also integrate with future technologies like AI-based analytics, license plate recognition, or IoT sensors.
Understanding the Cost of Access Control Systems
Initial Investment
This includes hardware (card readers, controllers, locks) and installation costs, which vary by building complexity.
Recurring Costs
Cloud-based systems may require monthly fees for storage or software licensing. These should be factored into your long-term budget.
Maintenance and Support
Choose a provider with clear service packages that cover updates, inspections, and troubleshooting.
Cost vs Value
Cheaper systems may save money upfront but often cost more long term through inefficiency, failures, or lack of scalability.
How to Choose the Right Provider for Your Access Control System
Experience and Licensing
Work with providers who have proven experience and licensed technicians who understand Australian security standards.
Local Knowledge
A provider familiar with your area understands local regulations and common security challenges.
Ongoing Support & Training
Ensure your provider offers 24/7 support, system documentation, and staff training.
Transparent Pricing
Choose companies that offer detailed, upfront pricing. Transparency builds trust and helps with accurate budgeting.
Future-Proofing Your System: How to Choose an Adaptable System
Embrace Technology
Select systems that support smart features, cloud integrations, and AI-powered analytics to stay ahead of evolving security needs.
Vendor Support
Ongoing vendor updates and upgrade paths help maintain performance and adaptability.
Modular Design
Modular systems allow you to upgrade or replace individual parts without overhauling the entire setup.
