I have used the Video Stream function to view internet cameras. However, the IP address of your network provider is constantly changing. So can we update that public IP address automatically?
Use a service like NoIP.com
You get a free unique url which you use in place of your public IP address. You then need to run an updater client somewhere on your network that keeps the NoIP service updated with your current public IP address. Many routers have an update client built in to them, that you can configure with your NoIP url and credentials.

Zerotier can also be used. Then no need for public IP.
