go2rtc as "proxy" - this made a huge difference and improvement (Istarted using RTSP streams directly into frigate, and the recorded videos lagged and was sometimes broken).
The Lowres RTSP stream (sub) for the Detect role as generally recommended, as frigate only uses a 300x300 pixel image for object detection.
The highres RTSP stream (main) for the Recording Role as generally recommended.
input_args: preset-rtsp-restream as recommedded for Reolink
Recording event on object detection
Take snapshots on event
The tracking of persons and cars
The use of a Coral stick for Object processing - instead of the CPU
