If they are doing this in Chinastan they can be doing it anywhere. You might find yourself a free camera.

A massive operation offers access to hacked camera feeds in bedrooms and at hotels.

Stolen videos captured by tens of thousands of security cameras at private properties throughout China are now for sale across social media, marketed as sex tapes.
That’s according to the South China Morning Post, which reported that the cost of each “tape” varies, depending on how salacious the material is — nudity and sex acts can fetch around $8 a piece, while just watching someone in a hotel room might just run around $3, the paper said.

The seller explained that besides hacking into vulnerable home-security cameras, there are groups of people installing cameras in random places across the country.
“I have a dozen people traveling around the country and install [sic] cameras wherever they go,” the seller bragged to his customers, the Post said. “Even if the hotel finds out, what we will lose is just a camera which is a few hundred yuan. We cut a couple of clips to sell online and we will cover that loss.”
