What is this thing in the hotel?

This should be a TV box. The TV box is an external device. Its advantage is that it can not occupy IRQ (mid-range), open the host and plug in&; PLAY (plug and play), without installing a driver, now many TV boxes have the function of collecting programs. At present, TV boxes can be divided into three categories, one is dedicated to shopping, the other is aimed at young people, and the other is specially designed for parents [1]. The effect of TV programs is directly related to its chip tuner, and the price is moderate. Its functions also include video recording, time shifting, video acquisition and compression, and listening to radio. Not only that, users can also post-edit the video shot by the TV card through the computer and burn it into a CD for storage.

So don't worry about the camera, it's not that stupid to install such a big device for you to find. Enjoy your stay.
