Seoul police say they filmed 1,600 motel guests in the past year in various states of undress and having sex. They did so with tiny wireless spy cameras set up in 42 motel rooms at 30 motels across South Korea, in 10 cities. The devices were hidden inside TVs, hair dryer holsters and electrical outlets. The voyeur gang raked in $6,200 for the feeds from 97 paid users of an undisclosed website; in all, there were 803 videos.
