in principle you can create a reverse proxy that routes requests to the webcam. Google it, there are lots of examples, BUT - and it can be a big “but”, not all web cams are easy to do this for....
You may need to experiment to get it working. .
Look up how to create a reverse proxy and then you need a location block something like this....(no guarantee!)
location /cam3/ {
proxy_set_header Host $http_host$request_uri;
proxy_pass http://cam.era.ip.addr:port/;
proxy_read_timeout 120s;
access_log on;
}
