Hi,
You may hit bandwidth constraint if you use USB2 cameras. Please refer to
connected more than two usb cameras problem on deepstream-app (Jetson Nano Dev Kit) - #12 by DaneLLL
Suggest try USB3 cameras and have external power supply.

Hi,
The case does not work on default devkit. Suggest you check other carrier board from our partners:
