Hi,
You would need to use USB3 cameras. Please refer to

connected more than two usb cameras problem on deepstream-app (Jetson Nano Dev Kit)

Hi, With further investigation, we found bandwidth limitation is hit in using USB2(High-Speed) cameras. High-Speed limit is 480Mbps. In the test, two E-Con See3CAM_CU135 are USB3(Super-Speed) cameras. Please use USB3 cameras to get 5Gbps bandwidth.
