While many modern security systems leverage cloud processing for AI-powered analytics, some solutions still offer on-premise or hybrid options. However, cloud-based approaches often introduce latency, privacy risks, and ongoing subscription fees.

Ubiquiti’s UniFi AI Key takes a bold, edge-based approach. It brings AI-powered security processing directly to your local network, eliminating the need for cloud services.

With real-time smart detections, AI-enhanced search, and facial recognition, the AI Key is built for organizations seeking a scalable, private, and cost-effective security solution.

In this blog, we will explore the UniFi AI Key's key features, how its AI-powered smart detections and alerts enhance security, a comparison between the AI Key and AI Port, its hardware specifications and performance, and how to deploy and scale it effectively for maximum efficiency.

Key Features of the UniFi AI Key

AI-Powered Smart Detections & Analysis

Processes up to 1,000 smart detections per hour
Detects people, vehicles, and objects with high accuracy
Enhance camera-based motion detection and event categorization
Optimizes AI-powered alerts for proactive security monitoring

NeXT AI Search – Find Footage Instantly with Natural Language Queries

Rather than manually reviewing footage, users can search video archives with natural language.

Example Queries:

"FedEx truck at the loading dock"
"Person wearing a blue hoodie"
"White SUV parked for over 10 minutes."

Speech-to-Text Transcription for AI Cameras

Converts spoken audio from AI Series cameras into searchable text
It allows security teams to review conversations without audio playback
Only available for AI Series cameras that support speech-smart detections

AI-Enhanced Face & License Plate Recognition

Enhances recognition capabilities for G4/G5 series cameras
Does not provide built-in AI detection—it improves upon the camera's existing recognition abilities
Queue-based processing affects real-time results

AI-Powered Alerts – Proactive Security Notifications

Configure up to five predefined smart detection queries
Set custom confidence thresholds to avoid false positives
Receive alerts when specific objects, people, or vehicles are detected

UniFi AI Key Hardware & Performance

Cutting-Edge AI Processing at the Network Edge

Unlike cloud-based solutions, the AI Key performs all AI computations locally, reducing reliance on external servers.

Hardware Specifications: Built for Speed & Efficiency

Processor: ARM Cortex-A78AE v8.2
Memory: 16GB LPDDR5
Storage: 128GB SSD
Power Consumption: 45W PoE++

Power & Deployment: PoE++ for Seamless Integration

Powered by PoE++, making installation simple and reliable
Compact design allows for easy placement in security setups

AI Key vs. AI Port: Which One is Right for You?

Feature	UniFi AI Key	UniFi AI Port
Processing Capacity	1,000 detections per hour	Real-time per camera
AI Features	Full AI Suite	Basic smart detection
Power Method	PoE++	PoE In/Out
Best For	Multi-camera security setups	Enhancing a single-camera
Price	$679	$199

Key Differences Between AI Key & AI Port

When to Choose the AI Key

If you need AI-powered security across multiple cameras
If you require advanced AI analytics, face recognition, and smart search

When to Choose the AI Port

If you need smart detection for a single-camera
If you want real-time object detection rather than batch processing

Camera Compatibility & Integration

Supported UniFi Cameras (G4, G5, AI Series)

Optimized for UniFi Protect
Supports advanced detection on G4/G5 models

How AI Key Works with Third-Party Cameras via AI Port

AI Key does not process third-party cameras directly
Must be paired with an AI Port for integration with ONVIF-supported cameras

Face & License Plate Recognition Performance

Works best with G4/G5 series cameras
Queue-based processing—first-in, first-out priority

Deployment & Scaling: How to Optimize AI Key in Your Security Setup

Setting Up the AI Key – Step-by-Step Guide

1. Connect via PoE++ power

2. Adopt the device into UniFi Protect

3. Check for and install the latest firmware updates

4. Navigate to UniFi Devices > AI Key > Settings

5. Select the following AI features:

Computer Vision Enhancement (NeXT AI Search, AI Alerts, NeXT AI Summary)
Speech to Text (AI Series cameras only)
License Plate Recognition (G4/G5 series cameras)
Face Recognition (G4/G5 series cameras)
Face Enhancement

Scaling AI Key for Large Surveillance Networks

Queue Limit: 200 events – Excess detections are discarded
Full queue processing may take up to 15 minutes
Supports multiple AI Keys per console for increased processing capacity
Performance depends on network bandwidth and system resources

Limitations of the UniFi AI Key

Requires a UniFi Protect ecosystem – Not compatible with third-party surveillance platforms
Queue-based processing for face/license plate recognition – Real-time results may be delayed in high-traffic environments
Potential learning curve – Advanced AI features require proper setup and configuration

Is the UniFi AI Key Right for You?

1. Who Benefits the Most from AI Key?

Businesses needing AI-powered security
Organizations requiring private, local processing
Security teams managing large surveillance setups

2. When the AI Port Might Be a Better Choice

If you only have one or two cameras
If you do not require advanced AI search and recognition

3. ROI & Cost Savings – No Cloud Fees, No Licensing Costs

One-time purchase, no subscriptions
Lower long-term costs compared to cloud-based AI solutions

The Bottom Line – Future-Proof Your Security with AI Key

With edge AI-powered security, real-time detections, and intelligent alerts, the UniFi AI Key delivers unmatched surveillance capabilities without cloud reliance.
