Yeah, that might just be me. What you are describing sounds completely alien to me. I still struggle with comprehending why people insist on bringing the basic stuff online -- my security cameras should not
require Internet access -- but I guess there's a reason I live in an old house on the countryside, and not in the middle of a city. :D
Cameras in each room? It's a privacy nightmare and I frankly don't trust my equipment, my network, nor myself to set that up safely. Especially if the cameras I own are any indication of how the rest work (hard-wired default passwords, security flaws, upload of FTP credentials to some Chinese business' servers, constant attempts at leaking data through DNS lookups when regular traffic is blocked, etc).
Thermostats and humidity sensors make sense if each room has it's own heaters/air conditioners, though.
