This guide draws from our Hyde Park workshop experience and explains what UniFi Access actually does, how it works in Johannesburg's environment, and what you need to know before installing one.
What Is UniFi Access and Why Johannesburg Businesses Need It
UniFi Access is Ubiquiti's enterprise-grade door control system. It manages who enters which doors, when, and creates an audit trail of every access event. Unlike traditional magnetic locks or keypads, UniFi Access integrates with your existing UniFi network—your WiFi, switches, and controllers—into one platform.
In Johannesburg, where load shedding affects almost every business, this matters. A poorly designed access control system fails when the power drops. UniFi Access uses Power over Ethernet (PoE), which means your network switch powers the door hardware directly. If your UPS backs up your network core properly, your doors stay secure and functional even during rolling blackouts. We've seen clients in Sandton, Midrand, and the northern suburbs avoid complete access failures by planning their PoE infrastructure correctly from the start.
The system works through your UniFi controller—the same device managing your WiFi and network cameras. You add users, assign access permissions per door, set time-based rules (e.g., unlock lobby doors only 8 am to 6 pm weekdays), and monitor every entry in real time. It's particularly valuable for office parks, medical practices, and retail chains where different staff need access to different areas.
UniFi Access Installation and Setup in Johannesburg
Installation isn't a weekend DIY project, even if you're technically confident. The UniFi Access ecosystem includes several components: the access reader (mounted on your door frame), the electronic strike or lock, a backup power module, network cabling, and integration with your UniFi controller. Each component must be sized for your specific door type, traffic volume, and building infrastructure.
Start with an assessment from a qualified technician. We charge from R599 for a comprehensive audit of your premises—this covers door types, existing wiring, network capability, power supply resilience, and integration with your current systems. This assessment prevents expensive mistakes later. Many clients in Johannesburg have found that their existing network infrastructure wasn't sufficient; running new Cat6A cabling through older office buildings or residential complexes often requires structural planning, especially in areas like Parkhurst or Illovo where older buildings lack cable routing.
The installation itself typically takes 2–5 working days depending on the number of doors and any structural work needed. Our team installs the hardware, configures the UniFi controller, sets up user roles and access schedules, and tests failover scenarios (like what happens when the controller loses connectivity). We also configure local access rules so doors remain functional even if your internet drops—critical in Johannesburg's unpredictable network environment.
One of the trickier aspects is power management. Every reader and lock draws power; if you're securing 8 doors, that's significant load on your PoE switches. We often recommend adding a UPS specifically for your network cabinet, separate from your general building power backup. During load shedding, your doors work; during an internet outage, they still work locally. That redundancy costs extra upfront but has saved countless clients from access chaos.
Common UniFi Access Issues We Fix in Hyde Park
We've resolved over 22,000 access control issues across our South Africa service area, including many UniFi-specific problems.
Reader connectivity loss: Readers drop offline when network cables are damaged (surprisingly common in high-traffic areas where furniture moves) or when PoE power delivery fails. We test every connection with a network meter and replace damaged cabling immediately.
Controller failure or network outages: If your UniFi controller goes down or your internet drops, what happens? This depends on how your system was configured. Poor setup means doors lock and nobody can enter. Good setup means doors remain accessible locally until the controller recovers. We review and upgrade configurations to ensure this doesn't catch you by surprise.
User synchronisation delays: Adding or revoking access sometimes takes a few seconds to propagate. In a high-security environment—a medical practice handling sensitive data, for instance—this lag can be a problem. We optimise the controller settings and network topology to minimise sync delay.
Physical damage and wear: Door hardware gets heavy use. Readers get bumped, locks stick, or cables get partially cut by vacuum cleaners. Our preventative maintenance visits catch these early.

Warranty, Support, and Long-Term Maintenance
We back all UniFi Access installations with up to a 3-year warranty covering hardware replacement, controller configuration, and onsite support. This means if a reader fails, we replace it. If your controller becomes corrupted, we restore it. If an access rule breaks after an update, we fix it—no call-out fees.
Beyond warranty, we offer annual maintenance contracts. For most Johannesburg businesses, this includes quarterly site visits, firmware updates, user audit reviews, and 24/7 phone support. Many clients in Randburg and Fourways prefer this peace of mind, especially businesses that rely on secure access (law firms, fintech offices, medical centres).
If you're also running Apple devices in your office—MacBooks on your network, iPads for staff—we can advise on integration. UniFi Access doesn't directly interface with Apple devices, but a well-designed network supports both seamlessly. We've helped over 15,000 businesses integrate their Apple ecosystems with business-grade infrastructure. If you have questions about compatibility, our contact page has direct technician chat.
For deeper technical documentation, Ubiquiti's official UniFi Access support page covers configuration in detail.
Cost and ROI in the Johannesburg Market
A single-door UniFi Access installation typically costs between R4,500 and R8,500 (hardware, installation, configuration). A four-door system runs R16,000–R28,000. Businesses often recover this cost within 18–24 months through reduced security incidents, eliminated lost keys and cards, and streamlined staff access management.
We've also seen businesses reduce insurance premiums by up to 15% after installing proper access control—insurers view detailed audit trails as a risk reduction.
If cost is a concern, start with one critical entry point (main office door, server room, client meeting area) and expand later. The UniFi controller scales; adding a fifth or tenth door is incremental.
Getting Started: Next Steps
Whether you manage a three-person office in Parkhurst or a 50-person practice in Sandton, UniFi Access is worth serious consideration. Load shedding and Johannesburg's network variability make a properly designed system essential—not optional.

Frequently Asked Questions
Q: Does UniFi Access work if the internet goes down?
Yes, with proper configuration. Readers use local authentication if the controller is temporarily unreachable. However, you cannot update permissions or add new users without controller connectivity. We always configure your system to stay functional during outages; this is part of the standard installation.
Q: Can I integrate UniFi Access with my existing CCTV cameras?
UniFi Access and UniFi Protect (the camera system) share the same controller, so yes. When someone accesses a door, the camera timestamp syncs, and you can review video of that exact moment. This is one of UniFi's strongest features for security auditing. We set this up as part of the full installation.
Q: How many users can I add to UniFi Access?
Theoretically unlimited, but practically most controllers handle 500–1000 active users smoothly. If you're managing a large office park with thousands of staff, you may use multiple controllers or a cloud-based setup. We assess your user base during the R599 audit.
Q: What's the difference between a UniFi Access reader and a standard electronic lock?
A UniFi reader is a networked device that communicates with your controller. A standard lock is dumb—it either locks or unlocks, with no audit trail or time-based rules. UniFi readers give you granular control, history, and integration with your network ecosystem. They're more sophisticated and more secure.
Q: Can I add UniFi Access to a rental office space?
Yes, but you'll need landlord permission and careful planning to avoid damage. We use non-destructive installation methods wherever possible—surface-mounted readers, adhesive backing, wireless readers (though we usually recommend wired for reliability). Discuss with your landlord and we'll advise on the best approach during your assessment.
Q: How often do I need to update UniFi Access firmware?
Ubiquiti releases updates every 4–8 weeks. We recommend updating every quarter as part of standard maintenance. We handle all updates remotely; no disruption to your access control during the process.
