At ZA Support, we have spent the last three years supporting businesses integrating UniFi networks into their physical security infrastructure. This is not theoretical. We have worked directly with property managers, tech teams, and business owners to move from legacy systems to cloud-managed access control. That experience has taught us what actually works in a Johannesburg context—and what creates problems.
This guide covers UniFi Access door control from a practical angle: what the system does, why businesses choose it, how integration works in our environment, and what support looks like when things go wrong.
What UniFi Access Actually Does
UniFi Access is Ubiquiti's cloud-managed door control system. Unlike older magnetic locks or card readers, it uses networked controllers, readers, and cloud management to centralise access policies across multiple doors and buildings.
In practice: a staff member taps their phone or credential card at a reader. The reader communicates with a local UniFi Dream Machine or controller. That controller validates the credential against cloud-based access policies. The door unlocks (or remains locked). Everything is logged.
The system integrates with UniFi Network—the same infrastructure managing your WiFi and switches. This matters. Businesses often have separate contractors managing WiFi, CCTV, and access control. UniFi Access runs on the same network backbone, meaning one team can manage it all.
For Johannesburg businesses, this integration simplifies network design. You are not running separate cabling for access control. Everything sits on Ethernet.
Why UniFi Access Makes Sense for Johannesburg Businesses
Security concerns in Johannesburg are real. Load shedding is real. Unreliable internet is a genuine problem in some areas. UniFi Access was designed with these constraints in mind.
Local failover: If cloud connectivity drops, readers continue to authenticate credentials locally using cached policies. Your doors do not lock permanently when Eskom cuts power or when your ISP hiccups. We have tested this during Stage 6 load shedding at client sites in Fourways and Bryanston. The system held.
Scalability: Whether you manage one office building or five properties across different suburbs, UniFi Access centralises policy. You add new buildings, new doors, new users—all from one dashboard. No separate systems to manage.
Integration with existing UniFi networks: If your business already runs UniFi WiFi and switching, access control becomes a natural extension. We have observed that businesses with existing UniFi infrastructure adopt access control faster because the network foundation is already proven.
Audit trails: Every door opening is logged with timestamp, user, and method (card, PIN, phone). This matters for POPIA compliance and for internal audits. If something goes wrong, you have the data.
The cost starts from around R599 for an assessment and initial scoping. Full installation for a small office (3–5 doors) typically sits between R8,000 and R15,000 depending on door hardware, wiring, and controller placement. Larger deployments cost more, but the per-door cost actually decreases.
Integration and Installation in the Hyde Park Context
UniFi Access requires three components: readers (door-mounted), controllers (local processing), and internet connectivity for cloud management.
The reader placement matters. In our Hyde Park workshop, we have worked with installers on reader height, angle, and weather protection. A reader in an external environment needs IP65 or IP67 rating. Johannesburg's summer heat and occasional flooding mean you cannot cut corners on weatherproofing.
Controllers sit in your network cabinet or server room. Most businesses run this on a UniFi Dream Machine—a combined gateway, controller, and security appliance. If your network is distributed across multiple buildings, you might run secondary controllers locally and sync policies via cloud.
Wiring is straightforward Ethernet. Readers connect to PoE (Power over Ethernet) switches. The controller connects to your internet gateway. This is standard Ubiquiti infrastructure—nothing exotic.
What complicates things: integration with existing door hardware. If you have expensive electronic locks already installed, you need to verify compatibility before committing. Some locks require dry-contact relays. Others use 12V pulse signals. We have seen projects delayed because the door hardware and UniFi readers were not compatible.
This is where external advice helps. Contact ZA Support for a pre-installation audit—we assess your existing doors, locks, and network, then provide a realistic scope and timeline.
Support, Troubleshooting, and Ongoing Management
UniFi Access fails in predictable ways. Readers lose network connectivity. Cloud policies fail to sync. Credentials stop working. Doors lock unexpectedly.
From our experience supporting over 12,000 networked devices in the Johannesburg area, access control issues usually stem from network problems, not the access system itself. A reader that cannot communicate with the controller is a network problem. A controller that cannot reach the cloud is an ISP problem. The UniFi system is doing what it should—but the underlying infrastructure is broken.
This is why we recommend a thorough network audit before installing UniFi Access. Is your cabling Cat6 or Cat5e? Are your PoE switches adequate? Is your internet connection stable? These questions matter.
We offer support plans starting from R599 per quarter, which includes remote troubleshooting, policy updates, credential management, and escalation to Ubiquiti if hardware fails. We also provide on-site support for installation and integration—useful if you are moving your access system from legacy hardware to UniFi.
Warranty typically covers three years on hardware and one year on labour. If a reader fails, you receive a replacement. If integration takes longer than quoted, we honour the original timeline within reason.
Long-term Reliability and Load Shedding Resilience
Johannesburg's load shedding creates unique challenges for access control. A system that depends entirely on cloud connectivity will fail during internet outages.
UniFi Access handles this through local caching and failover. Your controller stores access policies locally. If the cloud connection drops, readers continue operating using cached credentials. This is critical during load shedding—you do not want your entire access system going offline because Eskom is managing demand.
We recommend UPS (uninterruptible power supply) protection for your controller and core PoE switches. This costs roughly R2,500–R5,000 depending on load, but it ensures your access system survives extended power cuts. Given Stage 6 and Stage 8 rolling cuts, this is a worthwhile investment.
Battery-backed readers are also available. They add cost but give you additional resilience if your PoE power fails.
Getting Started with UniFi Access
The first step is a proper site assessment. We visit your premises, audit your existing doors and locks, test your network connectivity, and provide a detailed quote. This assessment costs R599 and typically takes 45 minutes.
From the assessment, we provide a phased installation plan. Phase 1 might be your main entry door and reception area. Phase 2 could be internal office doors. Phase 3 might be the server room or secure storage. This approach spreads cost and lets you validate the system before full rollout.
Book online at zasupport.com/book to schedule an assessment, or WhatsApp us on 064 529 5863 for a quick chat about your specific security needs.
If your business is already running UniFi infrastructure, mention that during booking—it often means faster installation and lower integration costs.
Maintenance and Credential Management
Once UniFi Access is live, ongoing management is straightforward but essential. User credentials expire. Staff members leave. New team members need access to specific doors.
We manage credentials through the UniFi cloud dashboard. Add a new staff member: create a credential (card, PIN, or phone-based), assign door permissions, and activate. Remove someone: disable their credential immediately. All of this happens without visiting the door hardware.
The system logs every access attempt. Compliance audits become simpler—you have proof of who accessed what, when, and from where. For POPIA purposes, access logs help demonstrate that you are controlling who can reach personal data.
We also recommend quarterly policy reviews: which doors do current staff need access to? Are there stale credentials that should be deactivated? Has your office layout changed? A 20-minute quarterly check prevents security drift.
If you are considering other network infrastructure upgrades—new WiFi, additional switches, or CCTV integration—mention that during your assessment. UniFi integrates with all of these, and a cohesive plan is more efficient than piecemeal upgrades.

Frequently Asked Questions
Q: Does UniFi Access work without internet?
Yes, partially. If cloud connectivity drops, your controller continues to authenticate credentials locally using cached policies. Doors remain functional. However, you cannot manage credentials or view logs until the connection restores. We recommend testing this during your assessment so you understand the failover behaviour.
Q: Can we use UniFi Access with our existing door locks?
Sometimes. It depends on the lock type and voltage. Most electronic locks work, but some older magnetic locks require custom wiring. We assess this during the R599 site visit and tell you honestly whether your existing hardware is compatible.
Q: What happens if the power goes out during load shedding?
Your PoE-powered readers will stop working unless you have UPS protection. The controller will also go offline. If you have a battery-backed UPS, critical doors remain operational. This is why we recommend UPS for any production access control system.
Q: How much does a full UniFi Access installation cost for a 10-door office?
Typically R25,000–R40,000 depending on door hardware, wiring complexity, and controller setup. This includes readers, cabling, controller, installation, and initial configuration. We provide a detailed quote after the site assessment.
Q: Can we manage UniFi Access remotely from overseas?
Yes. Everything is cloud-managed through the UniFi dashboard. You can activate credentials, disable users, and view access logs from anywhere with internet. This is useful for businesses with international head offices or remote decision-makers.
Q: Does UniFi Access integrate with our existing UniFi WiFi network?
Yes, that is a primary advantage. If you already have UniFi network infrastructure, access control installation is faster and cheaper because the underlying cabling and PoE switching are already in place. We often see integration costs drop by 30–40% for businesses with existing UniFi networks.
