Most people think of Ubiquiti as a networking company — and they are — but their UniFi Protect and UniFi Access products have quietly become one of the best value propositions in physical security. Enterprise-grade IP camera management, smart AI detection, and NFC door access control, all managed through the same polished interface as the rest of your UniFi infrastructure.
I run UniFi Protect on a UDM-Pro (Dream Machine Pro) with a mix of UniFi G4 Dome cameras, a G4 Doorbell, and two G5 Bullet cameras covering the exterior. UniFi Access manages two controlled entry points using UA-Lite readers and UniFi Access Hub hardware. This writeup covers the practical setup, smart detection configuration, and how these systems integrate with the broader UniFi ecosystem.
UniFi Protect Overview
UniFi Protect is a video surveillance platform that runs locally on UniFi hardware — no cloud dependency, no per-camera subscription, no monthly fees. Recording happens on-device (UDM-Pro internal drive or attached UNVR), and the footage stays on your hardware. This is a fundamental difference from consumer cameras like Ring or Nest that require cloud subscriptions for local recording and history.
Key hardware:
- UNVR — Dedicated 4-bay NVR appliance supporting up to 50 cameras and 4 hard drives. The enterprise choice for larger deployments.
- UDM-Pro / UDM-SE — All-in-one gateway with built-in Protect support. The UDM-SE adds a 3.5-inch drive bay and 8 PoE+ ports; the UDM-Pro uses M.2 storage (limited) but can connect to an external UNVR.
- Cameras — G4 Dome (indoor/outdoor), G4 Bullet (long-range outdoor), G4 Pro (4K), G5 series (upgraded sensors), AI Theta (360 degree), AI Pro (advanced detection).
Setting Up UniFi Protect
Protect is accessed from the UniFi OS portal on your gateway at https://<gateway-ip>. After adopting the application, cameras are discovered automatically if they are on the same L2 network or can be manually added by IP.
Initial configuration per camera:
- Recording mode — Choose from Continuous (records 24/7), Motion Only (records only when motion is detected), or Smart Detect (records on AI-detected events: person, vehicle, animal, package).
- Video quality — Set resolution and frame rate based on your storage constraints. I run primary streams at 1080p/15fps for most cameras, with the G5 Bullets running 2K/15fps for exterior coverage.
- Motion sensitivity — Tunable per camera. Lower sensitivity reduces false positives from trees and small animals; Smart Detect handles this more intelligently for G4/G5 cameras.
- Privacy zones — Draw masked regions on the camera view that are excluded from recording. Essential for neighbor privacy compliance.
Smart Detect: AI-Powered Events
Smart Detect is the standout feature of newer UniFi cameras. The AI runs entirely on the camera hardware — no cloud processing. Supported detection classes depend on the camera model:
| Detection Class | Cameras Supporting It |
|---|---|
| Person | G4 and G5 series, AI Pro, AI Theta |
| Vehicle | G4 Bullet, G5 Bullet, AI Pro |
| Animal | G4 series and above |
| Package | G4 Doorbell, G4 Pro |
| License Plate (LPR) | AI Pro, AI 360 |
Smart Detect dramatically reduces notification fatigue. Rather than triggering on every movement, you only get alerts when a person enters your driveway or a vehicle approaches your garage. The detection accuracy on the G5 cameras is impressive — false positives from shadows and lighting changes are rare compared to standard motion-based systems.
Storage Planning
Storage requirements depend on camera count, resolution, and recording mode. A useful estimate:
- 1080p continuous at 15fps — approximately 50–80 GB per camera per day
- 1080p motion-only — approximately 5–15 GB per camera per day (highly variable)
- Smart Detect only — minimal storage, events only
For a 7-camera setup running Smart Detect with a 30-day retention goal, a single 4 TB drive in the UNVR is more than sufficient. I use a 4 TB WD Purple (surveillance-rated) which has been running continuously for over a year without issues.
UniFi Access: Door Control
UniFi Access is Ubiquiti's access control platform. It integrates directly with UniFi OS and Protect, allowing you to associate camera views with door access events — when a door is unlocked, you see a clip of who used it.
The hardware stack for UniFi Access:
- UA Hub — The core controller for Access. Manages up to 10 doors, connects to UniFi OS via PoE. Required for each Access installation.
- UA-Lite / UA-Pro — Door readers. UA-Lite supports NFC (UniFi Access card or mobile NFC). UA-Pro adds a fingerprint scanner and PIN pad for multi-factor entry.
- UA-Lock — Smart lock for doors without traditional electric strikes. Battery-powered, communicates via Bluetooth/NFC.
- UA-Intercom — Video intercom station with 2-way audio and camera, integrated with UniFi Protect.
Configuring Access Points and Schedules
Under Access > Doors, you define each controlled entry point and assign readers to it. For each door you configure:
- Access groups — which users or NFC cards can open this door
- Schedule — when the door auto-unlocks (e.g., 8am–6pm weekdays) or is strictly card-only
- Entry delay — how long the strike stays energized after a valid credential
- Hold-open alarm — alert if the door is held open longer than a defined threshold
User credentials are managed under Access > Users. Each user can have multiple credentials: a physical NFC card, a mobile wallet credential (iOS/Android), or a PIN. You can revoke any credential instantly without physical key collection — a significant operational advantage over traditional locks.
Protect + Access Integration
The integration between Protect and Access is where the platform becomes greater than the sum of its parts. In the Protect timeline, access events appear as markers — you can jump directly to the camera view associated with a door unlock event. This creates an automatic audit trail: every badge access links to video evidence of who physically used that credential.
Practical use cases in my setup:
- Front door Access reader + G4 Doorbell camera — every entry attempt has associated video
- Server room Access reader + interior G4 Dome — physical access to critical infrastructure is logged with video
- Motion alerts from cameras automatically correlate with concurrent access events on the timeline
Privacy and Data Sovereignty
One of the most important aspects of UniFi Protect is that all data stays local. Footage is stored on your hardware, in your home or facility. There is no mandatory cloud upload, no subscription required for full-resolution local recording, and no third party with access to your camera feeds.
Ubiquiti does offer optional cloud access for remote viewing through the UniFi mobile app, but this is opt-in and routes traffic through Ubiquiti's relay servers rather than storing footage. For home use, I configure direct DDNS access to my UDM-Pro via a VPN connection for remote viewing, completely bypassing any cloud dependency.
Getting Started
For someone new to physical security systems, the UniFi ecosystem is the most accessible professional-grade entry point available. Start with a UDM-Pro or UDM-SE, add two or three G4 cameras for exterior coverage, and you have a functional surveillance system with 30-day retention in an afternoon. Add UniFi Access hardware when you are ready to extend into access control. The incremental hardware investment and the unified management experience make scaling this system straightforward in a way that mixing vendors never is.
