What is Frigate NVR?

Frigate is a free, open-source Network Video Recorder (NVR) software that uses artificial intelligence to detect objects in your security camera feeds. Unlike traditional NVRs that simply record 24/7, Frigate only records when it detects something important — like a person, car, package, or animal.

It was originally built to work seamlessly with Home Assistant, but it can also be used as a standalone NVR. Because of its excellent AI performance and low resource usage, Frigate has become one of the most popular choices for people looking for a free AI security camera system in 2025 and 2026.

Key Features of Frigate NVR

Frigate stands out from other NVR software because of its strong focus on AI object detection. Here are its main features:

Advanced AI Object Detection — Uses machine learning models to identify people, vehicles, packages, animals, and more with high accuracy.
Event-Based Recording — Only records when relevant activity is detected, saving massive amounts of storage space.
Low Latency Live View — Uses WebRTC for smooth, real-time camera viewing.
Coral TPU Support — Works extremely fast when paired with a Google Coral USB Accelerator.
Home Assistant Integration — One of the best NVRs for Home Assistant users.
Multi-Camera Support — Can handle dozens of cameras without performance issues.
Zone & Mask Configuration — Create custom detection zones and ignore areas (like roads or trees).
Mobile App & Notifications — Get instant alerts with snapshots through Home Assistant or other platforms.
Open Source & Free — Completely free with no subscriptions or hidden fees.

How Does Frigate NVR Work?

Frigate works differently from traditional security camera software:

Your IP cameras send video streams (RTSP) to Frigate.
Frigate analyzes every frame using AI to detect objects.
When an object is detected in a defined zone, it creates an event.
The event is recorded and saved with a snapshot.
You can review events easily through the clean web interface.

This smart approach means you’re not scrolling through hours of empty footage. You only see the important moments.

Who Should Use Frigate NVR?

Frigate is an excellent choice if you fall into any of these categories:

You want a free AI-powered NVR with no monthly fees
You already use or plan to use Home Assistant
You have multiple IP cameras and want smart detection
You’re technically comfortable or willing to learn
