What camera hardware do you have, and what do you hope to accomplish with it?
Your question is ambiguous.
Do you have an official Raspberry Pi camera module ( https://www.raspberrypi.org/products/camera-module-v2/
) that you want to use with an RPi Zero to implement an 'IP' cam?
Or do you have a commercial IP web cam that you hope to access and view from an RPiZero?
Or some other possiblity that I haven't thought of?
