Hello everyone, i just went over my detection speed and such and was wondering if anyone tried the different coral ai core speeds that you can trigger vie the libedgetpu1- max or - std.
Hoping to get any expereinces with the usb coral from someone who used different speeds yet.
Some info also here Coral Edge Standard vs Edge Maximum | by Elven Kim | Nov, 2023 | Medium
frigate controls this speed and it is already set to max
Oh ok, thx alot for the quick answer. So i have to tinker to find why my inference is ~40 ms with the coral on 4 cams with 5 fps detection framerate
Is this usb or pcie model?
I don’t think 40ms is bad speed for usb version but I forget. Do you see missing detections in logs?
What version frigate are you using?
What is hardware?
What’s is camera resolution for detect?
Is 40ms normal, average or worst seen?
10 ms is typical for USB coral on the default model.
important to note that camera resolution, number of cameras, etc. will not affect the corals inference time
5 cams
Detect: width: 1280, 720
5 fps
Should i go lower on resolution?

like I said, detect resolution will not affect coral inference speeds. The issue will be in the hardware interface, potentially the USB shares a BUS with other things and is overloaded or you’re using USB 2
