* Reduce framerate before downscaling It is cheaper to drop frames and downscale those that remain than it is to downscale all frames and then drop some of them. This is achieved with the filter chain `-cv fps=FPS,scale=W:H`, and perhaps was the original intention. The plain `-r` and `-s` flags do not execute in order though - they each put themselves at the *end* of the filterchain, so `-r FPS -s WxH` actually applies the scale filter first, and then the rate filter. This fix can halve the CPU used by the detect ffmpeg process. * Bring back hard rate limits
Frigate - NVR With Realtime Object Detection for IP Cameras
A complete and local NVR designed for Home Assistant with AI object detection. Uses OpenCV and Tensorflow to perform realtime object detection locally for IP cameras.
Use of a Google Coral Accelerator is optional, but highly recommended. The Coral will outperform even the best CPUs and can process 100+ FPS with very little overhead.
- Tight integration with Home Assistant via a custom component
- Designed to minimize resource use and maximize performance by only looking for objects when and where it is necessary
- Leverages multiprocessing heavily with an emphasis on realtime over processing every frame
- Uses a very low overhead motion detection to determine where to run object detection
- Object detection with TensorFlow runs in separate processes for maximum FPS
- Communicates over MQTT for easy integration into other systems
- Records video with retention settings based on detected objects
- 24/7 recording
- Re-streaming via RTSP to reduce the number of connections to your camera
- WebRTC & MSE support for low-latency live view
