Short for Virtual Private Network, a VPN allows you to access your home network securely using an encrypted tunnel from anywhere. In order to view the cameras remotely, it is recommend to setup a VPN rather than expose the StreamShuttle (or any service for that matter) directly to the internet. This allows you to access your cameras at no charge from anywhere. StreamShuttle comes with a built in WireGuard configuration wizard, allowing you to setup a secure VPN in just a couple of clicks.
