When a tourist checks into a hotel, the tour guide will say to turn on the mobile phone first when entering the room. What's the use?

When a tourist checks into a hotel, the tour guide will tell the reason why he turned on his mobile phone before entering the room: besides health and safety, the most important thing is personal privacy when choosing a hotel. After all, some hotels have installed pinhole cameras now, and they are still in a position that is difficult to find, so it is very annoying to spy on the privacy of guests.

After entering the room, if you don't turn on the light, you can quickly turn on your mobile phone, which can effectively avoid privacy leakage and make some people with bad hearts have no chance. Many people will have questions about how to check whether a camera is installed in a room with a mobile phone. If the method is wrong, you can't find it even with your mobile phone.

First of all, we need to understand the working principle of the camera. Although the camera is installed in a hidden place, it can't work without power. Secondly, the memory also has a certain amount of storage, which can't be kept all the time. Guests can't start work until they enter the room and insert the room card.

The correct inspection method is to insert the room card after entering the room and make the room electrified. This is where the camera starts to work. Close the curtains and turn off all the lights in the room. At this time, take out your mobile phone and scan it with the shooting function. Once found? Red dot? There may be a camera installed in this place. The next step must be carefully checked. Although you may not encounter this situation when you go out, you should be more careful and have a good sleep before moving in.

For the hotel, if such an incident is exposed, it may only be a temporary impact. The reasons why these shady hotels are repeatedly banned are very complicated, which is also a very difficult problem in hotel management and restriction. However, there is no good way to control the hotel at present. So, you're on your own. For most people nowadays, people have no habit of checking cameras. Pay close attention and check carefully when staying in a hotel.
