4k camera in jetson nano

could you please suggest as a 4k camera support on jetson nano. also, I want to know how can I get CCTV camera feed into jetson nano.

Hi,
About your first question, what frame rate do you need for 4K camera ? If you want 4K-30fps, it needs 4 lane mipi. The official nano carrier board can not support. You have to find other carrier board supplier. If you need the supplier info. Please let me know. We have 4K cameras(but it needs 4 lane MIPI interface). If you are interested of it. You can find them via below link.
