General discussion • Can Raspberry Pi 5 Handle Four USB Cameras for 1080p 30FPS ?

Hi Masters,

I recently started an autonomous driving project that requires using four USB cameras for image recognition. The resolution is 1920x1080 at 30FPS (the cameras output AHD, which is converted to USB via an AHD-to-USB capture card).

I would like to know if this can be achieved on the Raspberry Pi 5. Previously, I tried using two USB cameras on a Raspberry Pi 4 CM4 kit, but I could never open more than one camera simultaneously. I am unsure if this is due to hardware limitations or bandwidth constraints.

Is it because all four USB ports on the Raspberry Pi are handled by a single hub, so when one of them is USB 2.0, all the devices have to operate under USB 2.0 speeds, leading to insufficient bandwidth?

SO.
Can I use a 4-port USB 3.0 hub (with four USB 2.0 cameras connected to the hub) to connect to the Pi’s USB 3.0 port in order to maximize the bandwidth?

I am looking for an AI edge computing board that can handle simultaneous camera capture and image recognition. Any suggestions or insights would be greatly appreciated.

Best regards, and thanks in advance!
