Military bases too.
Thing is though, I don't consider this really critical. It's not like this devices sit at the core of your network and handle all of your traffic. You don't let them talk to anything out on the internet.
I guess the concern (besides geopolitical posturing) is that if there are lots of them everywhere, someone is going to mess up their network design and let them talk to anyone else on the internet. But this applies to pretty much any simple network device, and all other makes of IP camera. It's guaranteed that anything made by, popular cheap manufacturers will come with a raft of known vulnerabilities that never get patched.
