Use Sony's Xperia E2 as webcam for PC preferably by USB cable

I know that there are several options. I tried IP Webcam on Sony's Xperia E2104 - and on the Win10 desktop, IP Camera. I was able to find the phone's IP address from Settings etc; and was lead to believe that I could enter any port between 1024 & 49151 - so chose 8080. I don't know the correct port number and whether the phone should have camera open or IP Webcam. Would appreciate any guidance to inch me along to a solution.
