Commercial Door Access Control Systems: Cloud‑Based vs On‑Premise Solutions

 As businesses modernise their physical security infrastructure, commercial door access control systems have become essential for protecting people, property, and sensitive areas. But one of the biggest decisions organisations face is choosing between cloud‑based and on‑premise access control solutions. Each approach has advantages and trade‑offs, and the right choice depends on your organisation’s size, IT strategy, security requirements, and budget.

This guide explains both models and helps you make an informed decision.


What Are Commercial Door Access Control Systems?

Commercial door access control systems regulate who can enter specific parts of a building using electronic credentials instead of traditional keys. These credentials can include:

  • Keycards or fobs

  • PIN codes

  • Biometrics

  • Mobile credentials stored on smartphones

Leading security technology providers such as HID Global and Bosch Security Systems offer hardware and software components for modern access control solutions.


Cloud‑Based Access Control Solutions

Cloud‑based systems rely on remote servers hosted by the access control provider or a cloud platform such as Microsoft Azure. Administrators and security teams access the system via web portals or mobile apps.

Key Benefits

1. Remote Management

Administrators can manage access permissions, monitor activity logs, and issue credentials from anywhere—ideal for multi‑site enterprises and distributed teams.

2. Scalability

Cloud systems handle growth smoothly. Adding new doors or users usually requires minimal additional infrastructure.

3. Automatic Updates

Software updates and security patches are handled by the provider, ensuring you always have the latest features and protections.

4. Lower Upfront Costs

Cloud access control often operates on a subscription model, reducing upfront hardware and licensing expenses.

5. Mobile‑First Capability

Cloud platforms typically integrate seamlessly with mobile credentials, allowing users to unlock doors with smartphones—improving convenience and contactless access.

Potential Drawbacks

  • Ongoing Subscription Fees: While upfront costs are lower, you’ll pay recurring fees over time.

  • Internet Dependency: Reliable connectivity is essential. Outages can affect remote access monitoring.

  • Data Residency Concerns: Some businesses may need data to reside within specific jurisdictions for compliance.


On‑Premise Access Control Solutions

On‑premise systems host the access control software on local servers within your own facility or data centre. Your IT team installs, manages, and updates the system internally.

Key Benefits

1. Full Data Control

Your organisation maintains complete control over access logs and credentials, which some industries prefer for compliance or privacy reasons.

2. Offline Reliability

On‑premise solutions can continue working even if internet connectivity is interrupted, as long as local networks remain operational.

3. Customisation

IT teams can tailor the software to specific needs or integrate with local systems without relying on external cloud configurations.

Potential Drawbacks

  • Higher Upfront Costs: Local servers, licensing, and infrastructure can require significant capital investment.

  • Maintenance Burden: Your internal team must handle updates, backups, and security patches.

  • Scalability Limitations: Expanding to additional buildings or sites can be more complex and require additional infrastructure.

When to Choose Cloud‑Based Systems

Cloud solutions are ideal if:

  • You have multiple sites or remote offices

  • You need real‑time access monitoring from anywhere

  • You plan to use mobile credentials or smart device integration

  • You want automatic updates without IT overhead

  • You prefer subscription pricing over large capital investments

Cloud‑based access control is especially popular among organisations adopting hybrid work models and flexible office setups.


When to Choose On‑Premise Systems

On‑premise solutions are often preferred if:

  • You have strict data residency or compliance requirements

  • You have a strong internal IT team capable of managing infrastructure

  • You prioritise offline reliability during internet outages

  • You require deep customisation beyond standard cloud configurations

Industries with heightened privacy or regulatory demands, such as government facilities or critical infrastructure, might lean toward on‑premise models.


Integration Considerations

Both cloud‑based and on‑premise systems should support integration with other security tools, including:

  • CCTV and video surveillance

  • Visitor management systems

  • Time and attendance platforms

  • Intrusion detection systems

Integration enhances security visibility and improves operational workflows.

Additionally, many modern deployments support access control with mobile credentials, allowing employees to use their smartphones for authentication and contactless entry.


Maintenance and Support

Regular maintenance ensures long‑term reliability and performance for both types of systems:

For Cloud‑Based Systems

  • Provider — responsible for updates, backups, and infrastructure security

  • IT team — handles internal user management and API integrations

For On‑Premise Systems

  • Internal IT team — responsible for updates, troubleshooting, and backups

  • Vendor support — may deliver patch updates or advanced technical assistance

Clear service level agreements (SLAs) are essential, regardless of deployment model.


Security and Compliance

Security is a top priority for commercial door access control systems. Both cloud and on‑premise solutions should offer:

  • Encrypted communication between devices and servers

  • Role‑based access controls

  • Detailed audit logs

  • Compliance with regulations such as GDPR

Evaluate vendors on their security track record, data handling practices, and support for secure authentication standards.


Final Thoughts

Choosing between cloud‑based and on‑premise commercial door access control systems depends on your organisation’s priorities, resources, and long‑term strategy. Cloud systems offer flexibility, scalability, and remote management, making them attractive for today’s hybrid and distributed workplaces. On‑premise solutions appeal to organisations seeking complete data control and offline reliability.
