That seems low for a Frigate setup with a Coral and suggests something else isn't right. Im running ~20 1080p cameras on two Corals right now. The general rule of thumb is 8-16 cameras per Coral, but it all depends on frequency Frigate is having to pass frames to the detector. Inference time per frame portion passed to the coral is about 10ms (100 detections a second), which is fast enough to cover a good number of cameras.

Worth noting most of the time the Corals sit idle in many setups, as Frigate only wakes them up if it detects motion with simpler algorithms on the CPU first. You gain capacity for a further 100 detections/sec for every Coral you add essentially. The corals are not sitting watching every single frame from every camera, which I think is a common misconception about Frigate.

It's worthwhile to spend some time with the docs - the mistake I always see made is folks passing a full fat 4k stream for detection at some silly FPS, which generally doesn't make the detection work any better and greatly increases processing costs.

If your six cameras really are generating enough events (100 a second) to saturate a coral, I'd be looking at what else I screwed up!
