Hi guys,
I am looking for a Machine Vision camera that can capture 60 fps @ 4K resolution with USB3.0.
Is there anything out there in terms of on-camera-compression or something comparable?
I know I could probably switch interfaces to CoaX, but since the setup is designed for USB3.0 at this point, I would love to go with that.
Best regards
Peter

USB3 Vision does not currently support any sort of compressed video formats. Even at 8-bit Mono format, 3840x2160x60fps is almost 4GB/s, well above existing USB3 Vision cameras (~450MB/s) and even future ones that could use USB 3.2's dual-lane, Gen2 10Gbit mode (~2GB/s). Is this color data that you are acquiring?
What are you intending to do with the video? I suspect that will drive a lot of your decisions.

I am not sure that this is much of help but 5GigE can give you those speed.

But that is a lot of data to process like the previous post said. Those cameras are new in the market. So I am not sure how will IMAQdx work with them. You can ask NI.

Those are still only 5Gbit (roughly 500MB/s), so almost an order of magnitude slower than the 4GB/s needed for uncompressed 4K video at 60fps.

Hi peterboi,
as users stated previously, you won't be able to achieve it with this serial bus. I checked the configurator of Edmund and Basler and 4k camera can achieve roughly 42-47 FPS.
Best,

Thank you very much for your help!
I found this 4K camera from Basler [1], which seems to be a great fit for my application. It does not deliver 60 fps @ 4K, but 42 fps, which may be also fine. I need to test 🙂

Oops, somehow my math was off by 10 on my previous calculation. Unfortunately USB3 cameras with a Gen1 (5Gbit) interface will not be able to quite get to 60fps at 4k. I suppose you could potentially crop the image slightly if you wanted to maximize speed and didn't need the whole 4k.
