Setting up network-based access control for a shared office

A shared office needs to give the right people convenient entry without turning security into a daily obstacle. Members may arrive early, work after hours, host visitors, or move between meeting rooms and private work areas. A network-based access control system connects doors, credentials, cameras, alarms and management software so these activities can be governed from one place.

The most effective setup begins with the office’s operating model rather than with a particular lock or app. A small coworking site in Brisbane may need a simple front-door reader and several smart locks, while a multi-floor workplace in Sydney or Melbourne may require separate zones, reception controls and integration with a booking platform. The system should match the building, workforce and level of risk.

Australian privacy and workplace requirements also deserve attention from the first planning meeting. Access records, photographs, facial templates and visitor details can be personal information under the Privacy Act 1988 and the Australian Privacy Principles. A clear purpose, limited retention period and transparent staff notice help create a system that is secure, practical and trusted.

Define the site and access policy

Start by mapping every entry point and deciding what each area protects. Include the street entrance, reception, lift lobby, shared desks, meeting rooms, storage areas, server cupboards, staff kitchens and emergency exits. Record whether each door is internal or external, how it is currently locked, whether it must allow free exit, and what happens during a power or network failure.

Next, create access groups instead of assigning permissions one person at a time. Typical groups include members, staff, cleaners, building management, contractors and visitors. A member might enter the main office from 7 am to 9 pm, while a cleaner receives access only to specified areas between scheduled hours. Temporary credentials should automatically expire rather than relying on someone to remember to revoke them.

The policy should cover lost phones, forgotten PINs, former employees, tailgating, deliveries and after-hours incidents. Decide who can approve access, who can view logs and how quickly a credential must be disabled. In Australia, workplaces may also need to coordinate these rules with building management, workplace health and safety procedures and fire evacuation requirements. An electronic lock must never compromise an approved emergency egress arrangement.

Select credentials and system architecture

Most shared offices use a combination of mobile credentials, access cards, PINs and intercom verification. Smartphone access is convenient for members who already use their phones for bookings and payments, but a card or fob remains useful for visitors, staff without compatible devices and situations where a phone battery is flat. Avoid making one credential type the only way to enter unless there is a robust fallback.

Biometric options, including fingerprint or facial recognition, can reduce credential sharing, yet they require particularly careful privacy management. Collect only what is necessary, explain how the information will be used and consider whether a less intrusive option can provide the same protection. A facial image used for identity verification may create greater compliance and trust obligations than an ordinary access card.

Choose between a cloud-managed, on-premises or hybrid platform. Cloud management makes it easier for an operator to add members from a reception desk or another location, and it can support several offices across Australia. An on-premises controller may suit a site with strict internal data requirements. A hybrid model can keep door decisions running locally while synchronising events with a central dashboard.

Check interoperability before buying hardware. The controller, readers, electric strikes, magnetic locks, intercom, video system, visitor management software and coworking booking platform should work together through supported standards or documented APIs. A low-cost reader that cannot export events or integrate with the membership database can create expensive manual work later.

Build a secure network foundation

Treat door controllers as connected business devices, not as ordinary office equipment. Place them on a separate network segment or VLAN with tightly limited communication to management servers and approved services. Keep staff laptops, guest Wi-Fi, printers, cameras and access hardware separated according to their risk and function.

A secure network is especially important when the office depends on a standard NBN connection, shared building internet or a wireless bridge between floors. Guidance about the risks of unsecured Wi-Fi is relevant here: weak passwords, outdated firmware and poorly configured routers can expose more than browsing activity. Change default administrator credentials, enable strong encryption, restrict remote administration and maintain current firmware.

Use wired Ethernet and Power over Ethernet where possible for fixed readers and controllers. This reduces battery maintenance and gives the installer a more predictable connection. For doors in difficult locations, use business-grade wireless equipment with a dedicated network rather than placing controllers on the same network as member devices.

Plan resilience before installation. Consider an uninterruptible power supply for the network rack, a backup internet connection for cloud services and local door rules that continue during a temporary outage. Decide whether each door should remain locked or unlocked during a failure, taking into account security, evacuation and the practical needs of the building.

Install hardware and configure permissions

Hardware installation should be completed by suitably qualified professionals who understand both access control and the existing door hardware. Reader height, weather protection, cable routing and lock alignment affect daily reliability. External doors in coastal areas such as Perth, Adelaide or parts of Queensland may need equipment rated for heat, dust, moisture or salt exposure.

Install readers where users can present a card or phone without blocking a corridor. Keep request-to-exit devices and emergency release mechanisms clearly identifiable. A door position sensor is valuable because it can report a door held open, forced entry or a lock that failed to close. For a reception area, an intercom or video verification device can allow staff to manage deliveries and guests without issuing permanent credentials.

Create a permission matrix before entering rules into the management console. For every group, specify doors, days, time windows and approval authority. Apply the principle of least privilege: a member who rents a desk does not automatically need access to a private office, equipment room or another tenant’s meeting space.

Connect the access platform to the membership or booking system only after defining the data flow. A cancelled membership should trigger a reliable deactivation process, but an integration error should not silently grant access. Use unique administrator accounts, multi-factor authentication and separate roles for installers, reception staff and system owners. Record configuration changes so an unexpected permission can be traced.

Test security, privacy and daily operation

Run structured tests before opening the system to members. Verify valid and expired cards, mobile credentials, temporary visitor passes, denied access, multiple users at once, door-held-open alerts and after-hours rules. Test every relevant failure condition, including loss of internet, power interruption, controller restart and a disconnected reader.

Check that emergency release arrangements operate as required and that people can leave safely. Walk through the site at busy periods to identify tailgating, queues and awkward reader positions. A secure door that encourages members to hold it open for the next person may perform poorly in real use, so combine technology with clear signage and staff procedures.

Audit logs should show who used which credential, at what time and at which door. Keep event data only for a defined business or safety purpose, restrict viewing rights and protect exports. If cameras or biometric functions are included, provide an appropriate privacy notice and assess whether collection, storage and disclosure align with Australian privacy obligations. Establish a process for handling access-data requests and potential breaches.

Alert thresholds require sensible interpretation. An unusual burst of denied entries may indicate a stolen credential, a faulty reader or a member who has forgotten a new PIN. When analysing occupancy or event patterns, raw figures need context; the distinction between a running count and a true count explanation offers a useful reminder that a number can be misleading when the underlying sample or conditions change.

Operate, maintain and review the system

Assign ongoing ownership to a named person or team. Daily tasks may include checking forced-door alerts, approving visitor access and responding to failed credentials. Weekly or monthly tasks can include reviewing inactive accounts, testing selected readers, checking battery levels and confirming that new starters and departures are reflected in the system.

Create a joiner, mover and leaver process with the office manager or human resources contact. New members should receive the minimum access needed for their booking or membership tier. A person changing from a day desk to a private suite may need a new access group, while a departing employee or contractor should be disabled promptly across every connected system.

Keep an asset register containing door locations, controller serial numbers, firmware versions, network addresses, warranty details and installer contacts. Schedule maintenance for locks, closers, batteries and backup power. Arrange software updates during low-use periods and retain a tested recovery procedure rather than assuming that a cloud dashboard alone is a backup.

Review the system after incidents, building changes and tenancy changes. A new entrance, renovated meeting room or additional coworking floor can create gaps in permissions and network design. For a regional operator supporting sites across New South Wales, Victoria or Queensland, central monitoring and documented standards can provide consistency while allowing each location to reflect its building and local operating needs.

NSC can help shared-office operators assess connectivity, select suitable devices, configure secure networks and integrate access control with broader ICT services. Arrange a practical site assessment to turn the office layout, membership model and security requirements into a reliable access plan.
