Since our camera supports the UPnP protocol ( port will be opened at the public network exit to directly reach the camera),
At the same time, your home has a public network ip, there are a large number of hackers on the Internet that do all port scans for the public IP. As long as the hacker scans the port, the router will warn you.
But opening the port does not mean that it will be invaded. Netvue uses a private protocol, hackers do not know the content of our protocol or the key.
You could choose to turn off the UPnP function of your router if you are worried about it.
