Similar to my question. I don't understand how these things are on the internet - what does that mean? I haven't been able to find technical details.
If I have a basic home firewall (e.g. Netgear) - with uPNP disabled - are these things on the "internet?" Are these devices found via portscan?
I went through this when looking at baby monitors. I only want to use them in my house - on the local WiFi. Are these things tunneling out to "the cloud" and are accessible through another channel? Can they be blocked at the perimeter of the house network - using basic equipment?
In the baby monitor case I decided to go with a proprietary model without "internet" features.
