Hi, I should be getting a new internet connection in the next month or so and I'm not sure if I need to spend the extra on a static ip address?... about $10/month My setup is all Dahua cameras with a Dahua NVR without built in POE. The goal is to be able to view the cameras remotely via a VPN Server setup on a router. So, the question is will a static ip make this easier? Is it essential?
