I guess I'm not clear on how things are supposed to work. It sounded to me as if the camera was uploading videos into their cloud and if someone wanted to view it they would access the cloud and not the camera directly. > > The system is Fedora 27, usually updated each day, and I depend on firewalld, > selinux, and the dd-wrt router firewall to provide security which seems to me to > make it a Fedora related question. I apologize if that is too broad an interpretation. Right, your system is F27 but I didn't see where your system was interacting with the camera. And, if things worked as I thought they would in that videos are getting uploaded to the cloud and someone external to your LAN was also just connecting to the cloud then there would seem little chance of a problem. The problem could be if one accessed the camera itself from outside of your LAN. It just seemed to me that wasn't going to be the case. > > I know that there are a number of those systems for remote viewing with "internet > cameras" being offered and typically the information provided to the user is > favorable.

So, potentially, someone could spy on you. I've not heard of an attack where someone gains control of an IP camera and then launches an attack on other devices like your F27 system. -- A motto of mine is: When in doubt, try it out
