I think consumer/customer is the right term in this situation. Even though I could build an isolated network with ethernet cables and security camera's, we're usually left with the other people, myself included, that wouldn't always be able to do research and come up with the best solution. That's why I want to outsource that by purchasing something. Which is why we're left with this freemarket of vulnerable devices and practises. People setting up security camera's usually do a good job. Consumers do not.
