Frigate: Real-Time Local Object Detection for Your IP Cameras

Ever wanted to add a smart brain to your security cameras without shipping all your video data to the cloud? Most DIY solutions are either privacy nightmares or too simplistic. What if you could run real-time object detection locally, identifying people, cars, and pets, while keeping everything on your own hardware?

That's exactly what Frigate does. It's an open-source NVR (Network Video Recorder) that uses OpenCV and TensorFlow to perform object detection on video feeds from IP cameras. It processes the video locally on your server, sends alerts for the objects you care about, and integrates seamlessly with home automation platforms.

What It Does

Frigate is a self-hosted video surveillance application. You point it at your RTSP streams from IP cameras, and it continuously analyzes the video using a local TensorFlow Lite model. It can identify and label objects like people, cars, dogs, and bicycles in real time. Instead of just recording motion, it records specific events—like a person entering your driveway—and makes those clips easily searchable.

Why It's Cool

The local processing is the killer feature. No monthly fees, no lag sending footage to a third-party server, and total control over your data. It's privacy-focused by design.

Technically, it's clever about performance. It uses OpenCV for hardware-accelerated video decoding (think Intel Quick Sync or Raspberry Pi GPU) to keep CPU usage manageable. You can run it on modest hardware, from a Raspberry Pi 4 to a dedicated home server with a Coral AI Accelerator for blazing-fast detection.

The Home Assistant integration is top-notch. You can create automations based on what Frigate sees: get a notification when a package is delivered, turn on lights when a person is detected after dark, or ignore events triggered just by your dog.

How to Try It

The easiest way to get started is with Docker. If you have Docker and Docker Compose installed, you can be up and running with a sample configuration in minutes.

1. Clone the repository to check out the docs and example files:

   git clone https://github.com/blakeblackshear/frigate.git
   

2. The project provides a detailed docker-compose.yml example and a config.yml template. You'll need to adjust the config file with your camera's RTSP stream URLs.
3. Run docker-compose up and navigate to the web UI (by default at http://localhost:5000).

Final Thoughts

Frigate is one of those projects that turns a complex problem into something approachable. It respects your privacy, avoids vendor lock-in, and leverages modern machine learning in a practical way. As a developer, it's a fantastic base to build on—whether you're tweaking detection models, crafting custom automations, or just want a reliable, local surveillance system. It demonstrates how open-source tools can create solutions that are often better than commercial offerings.
