Do hotels generally have cameras?

It is a small probability event that cameras are found in hotel rooms. Some are installed by people staying in the hotel, but some are installed in cooperation with the hotel, and the hotel pretends not to know about it.

In mid-2019, a couple visiting Zhengzhou, Henan from out of town discovered a pinhole camera in a socket in their hotel room. On the night of the incident, the police conducted random checks on four other rooms in the hotel involved and also found pinhole cameras. The person in charge of the hotel said that the camera was too hidden and they didn't notice it, saying that this happened in 80% of hotels in Zhengzhou. As soon as this statement came out, it caused a sensation on the Internet. As a result, many self-media denounced the hotel and published many tutorials on checking the cameras.

That’s why there are a large number of 80% hotels equipped with cameras on the Internet, but in fact this is only a very small probability.

Notes:

1. Pinhole cameras are most likely to be installed in these locations: roof (good line of sight), lamp holders, power panels, smoke detectors, fire sprinklers , empty books on the bookshelf, folders, TVs, behind the sound network of the stereo, under the edges of tables and chairs, electrical appliances hung on the wall, such as clocks, air conditioners, ventilation fans, alarm clocks, decorations on the bedside table, etc.

2. At night, turn off the lights in the room. Make sure that no other electrical equipment is powered on, then it is a strict dark room. At this moment, turn on the camera of the mobile phone, then use the lens to focus on the key parts, keep your eyes on the screen of the mobile phone, and scan around in this way. If there is an infrared light, then in There will be bright spots on the screen of the mobile phone. After discovering the bright spot, you are 100% sure that it is the location of the pinhole camera.
