What Is UniFi NVR API Usage and How to Leverage It

Imagine you’ve just set up your dream home security system. You’ve spent hours mounting cameras, running cables, and configuring your UniFi NVR (Network Video Recorder). Everything works perfectly—until you realize that you want to do more than just view footage. Maybe you want to trigger alerts when someone enters your yard, integrate your cameras with smart lights, or pull analytics on foot traffic. That’s where the UniFi NVR API comes in.

The UniFi NVR API is like a secret backdoor to your security system, letting you interact with your cameras and NVR in ways the standard web interface doesn’t allow. It’s not just for tech wizards—once you understand the basics, you can automate tasks, create custom alerts, and even build your own dashboard. Whether you’re a homeowner, a small business owner, or an IT professional managing a multi-site setup, the API opens up a world of possibilities. But like any powerful tool, it comes with its quirks and learning curve. In this guide, I’ll break down what the UniFi NVR API is, how it works, and—most importantly—how you can use it to make your life easier.

Understanding the UniFi NVR API: The Basics

The UniFi NVR API is a set of programming interfaces that lets you send commands to and receive data from your UniFi NVR and connected cameras. Think of it as a language your devices use to talk to each other—or to your custom scripts, apps, or third-party tools. Unlike the user-friendly web interface, the API requires some technical know-how, but the payoff is huge: automation, customization, and integration.

What Can the API Do?

• Retrieve live and recorded video feeds: Pull camera footage on demand or stream it to other platforms.
• Manage camera settings: Adjust resolution, motion detection zones, or recording schedules programmatically.
• Trigger events: Send alerts to your phone, email, or smart home devices when motion is detected.
• Access analytics: Extract data on motion events, camera status, or storage usage.
• Integrate with other tools: Sync with IFTTT, Home Assistant, Node-RED, or even your CRM system.

How the API Works (Without the Jargon)

The UniFi NVR API uses HTTP requests (like visiting a website) to communicate. You send a request (e.g., “Get the last 10 motion events from Camera 3”), and the NVR responds with data, usually in JSON format. It’s similar to ordering food via a delivery app: you send a request, and the kitchen (your NVR) sends back what you asked for.

There are two main types of interactions:

• REST API: Simple, stateless requests (e.g., “Get camera list”).
• WebSocket: Real-time updates (e.g., “Notify me when motion starts”).

For most users, the REST API is the starting point. It’s easier to learn and works well for one-off tasks or scheduled jobs.

Why Use the UniFi NVR API? Real-World Use Cases

The API isn’t just for “because I can” projects. It solves real problems and adds value to your security setup. Here are some practical ways people use it:

1. Automate Alerts and Notifications

Instead of checking your phone every time your camera detects motion, use the API to customize alerts. For example:

• Only notify you during business hours.
• Send a Slack message to your team if a delivery arrives.
• Trigger a smart light to flash when someone approaches your front door.

Example: A small business owner uses the API to send a Discord alert to employees when the backdoor camera detects motion after 6 PM. No more missed deliveries or break-in scares.

2. Build a Custom Dashboard

The default UniFi interface is great, but what if you want a single screen showing all critical info? With the API, you can:

• Display live camera feeds on a wall-mounted tablet.
• Show motion event counts over time (e.g., “12 people entered the warehouse today”).
• Integrate with weather data to correlate motion events with rain (e.g., “More deliveries on rainy days”).

Tip: Use tools like Grafana or Node-RED to visualize API data without writing code from scratch.

3. Sync with Smart Home Systems

Love your UniFi cameras but use Home Assistant for smart lights? The API lets you bridge the gap. For instance:

• Turn on lights when motion is detected.
• Arm your alarm system if a camera loses connection.
• Play a chime on your smart speaker when a delivery arrives.

Pro tip: Use IFTTT’s webhooks to connect the API to Alexa, Google Home, or other platforms.

4. Extract Data for Analytics

Want to know how often your store gets foot traffic? The API can pull motion event logs and export them to Google Sheets or Excel. You could even:

• Identify peak hours.
• Track employee movement (for security, not surveillance!).
• Audit camera uptime.

Getting Started: How to Access and Use the API

Now that you’re sold on the API’s potential, let’s get your hands dirty. Here’s how to start using it, step by step.

Step 1: Find Your NVR’s API Endpoint

Every UniFi NVR has a unique API endpoint (a web address). To find it:

1. Log into your NVR’s web interface.
2. Go to Settings > System > Advanced.
3. Look for the “API” or “Local API” section. The endpoint is usually https://[your-nvr-ip]:7443/api.

Note: If you’re using the UniFi Cloud, the endpoint might differ. Check the official docs.

Step 2: Authenticate (Log In)

To use the API, you need to “log in” programmatically. This involves:

1. Sending a POST request to /api/login with your NVR username/password.
2. Storing the returned session cookie for future requests.

Example (using cURL):

curl -X POST "https://192.168.1.100:7443/api/login" \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"your_password"}'

Tip: Use tools like Postman or Insomnia to test API calls without coding.

Step 3: Explore Available Endpoints

The UniFi NVR API has endpoints for:

• Cameras: /api/cameras (list all cameras).
• Events: /api/events (get motion events).
• Recordings: /api/recordings (download clips).
• Settings: /api/settings (adjust camera settings).

Example: To get a list of cameras, send a GET request to /api/cameras. You’ll get a JSON response with camera names, IDs, and status.

Step 4: Handle Rate Limits and Errors

The API has rate limits (usually 10 requests/second). If you exceed them, you’ll get a 429 error. Always:

• Add delays between requests (e.g., 0.1 seconds).
• Check the response status code (200 = success, 401 = login error).
• Use try-catch blocks in your code to handle errors gracefully.

Tools and Libraries to Simplify API Usage

You don’t need to build everything from scratch. Here are some tools and libraries that make working with the UniFi NVR API easier:

1. UniFi-Protect API (Official and Unofficial)

Ubiquiti’s newer “UniFi Protect” system has a more robust API than older NVRs. Even if you’re on an older NVR, check if your firmware supports Protect features. Key tools:

• Official UniFi Protect API: Requires a subscription but offers better docs and stability.
• unifi-protect (GitHub): A community-maintained Python library for interacting with the API. Great for beginners.

Example: Using unifi-protect, you can write a Python script to save motion-triggered clips to Google Drive.

2. Node-RED (For Non-Coders)

Node-RED is a visual programming tool that lets you create API workflows without writing code. For instance:

• Drag a “HTTP request” node to pull camera data.
• Use a “function” node to filter motion events.
• Send alerts via email or Telegram.

Tip: Install the node-red-contrib-unifi package for pre-built UniFi nodes.

3. Home Assistant Integration

If you use Home Assistant, the built-in UniFi integration can:

• Expose camera feeds as entities.
• Trigger automations based on motion events.
• Show camera status on your dashboard.

Pro tip: Enable the “motion detection” sensor in Home Assistant to create custom alerts.

4. IFTTT (For Simple Automations)

IFTTT’s “webhooks” let you connect the API to 700+ services. For example:

• “If motion is detected, send a WhatsApp message.”
• “If a camera goes offline, log it in Google Sheets.”

Common Challenges and How to Overcome Them

The UniFi NVR API is powerful, but it’s not perfect. Here are common hurdles and how to tackle them:

1. Authentication Issues

• Problem: Sessions expire quickly (usually 1 hour).
• Solution: Automatically re-login when you get a 401 error. Or, use the “remember me” option in your login request.

2. Inconsistent Documentation

• Problem: Official docs are sparse; you’ll rely on community forums.
• Solution: Join the Ubiquiti Community. Search for “API” + your NVR model. Bookmark this unofficial API reference.

3. Security Concerns

• Problem: The API sends data over HTTPS, but credentials are visible in code.
• Solution: Use environment variables to store passwords. Never hardcode them in scripts.

4. Camera Compatibility

• Problem: Older cameras (e.g., G3) have limited API support.
• Solution: Check the compatibility list. Upgrade to G4/G5 models for better features.

5. Performance Bottlenecks

• Problem: Too many API calls can slow down your NVR.
• Solution: Cache data (e.g., store camera lists in a file). Use webhooks for real-time updates instead of polling.
