Frigate NVR RTSP Stream Optimization & Coral TPU Guide
Optimize dual-stream RTSP setups in Frigate NVR to achieve 100+ FPS object detection with minimal CPU load.
Need an active live RTSP stream to test this integration?
Generate a free 20-minute authenticated live H.264 video feed with frame counters to test in VLC, OpenCV, or NVR software.
#1Separating Detect and Record Streams
In Frigate config.yml, always bind the low-resolution sub-stream (e.g. 640x360) for AI detection and the full 4K main-stream for recording. You can generate separate main and sub-stream URLs with our IP Camera RTSP URL Builder:
