The camera was found in the hotel room. This is a small probability event. Some were installed by people living in hotels, but some were installed in cooperation with hotels. The hotel pretended not to know about it.

In the middle of 2065438+2009, a couple who came from other places to Zhengzhou, Henan Province, found a pinhole camera on the socket of a hotel room where they stayed. On the night of the incident, the police conducted a spot check on the other four rooms of 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 find it, saying that 80% of hotels in Zhengzhou had this situation. When this statement came out, it caused a sensation on the Internet. As a result, there are a lot of self-media denunciations about hotels, and there are also many tutorials for checking cameras.

This is why a large number of 80% hotels on the Internet have installed cameras, but in fact this is only a small probability.

Precautions:

1. Pinhole cameras are most likely to be installed in these locations: roofs (with good sight), lamp holders, power boards, smoke detectors, fire sprinklers, books hollowed out on bookshelves, folders, televisions, the back of stereo networks, the lower edges of tables and chairs, and electrical appliances hanging on walls, such as clocks, air conditioners, ventilators, alarm clocks on nightstands, decorations, etc.

Turn off the lights in the room at night. It is a strict darkroom when no other electrical equipment is electrified. Now turn on the camera of the mobile phone, then aim the camera at the key parts, and keep your eyes on the screen of the mobile phone, so that if there is infrared light, there will be bright spots on the screen of the mobile phone. After finding the bright spot, 100% determine where the pinhole camera is.
