Hotel photos don't turn on the lights

Hotels are very important for people who go out, especially for tourists, because staying outside for a few days is very important for comfort and safety.

I believe everyone has heard the tour guide say that when entering a hotel room, you should do this with your mobile phone camera first, and then turn on the light. Through this step, you can find the hidden camera.

So how to operate specifically?

We continue to look down.

First of all, when we enter the room, we should close all the curtains, close the door and don't turn on the light, so that the room will be in a dark state.

Then, take out our mobile phones, turn on the camera, and aim the camera at every corner of the room, especially at the bedside and the position facing the bed, such as routers and televisions. , should focus on scanning.

If there is no red dot on the screen, then this room is relatively safe, and there is a high probability that there will be no hidden camera.

Because this camera takes pictures by infrared rays, it will be displayed on the screen.

When there is no problem after inspection, we will turn on the light again, and then everything will be fine.

However, although this inspection has a certain effect.

But with the progress of technology, cameras will continue to improve. At present, there are pinhole cameras that don't need infrared rays, so we still can't take it lightly.

You can choose a more formal hotel, don't go to that kind of small hotel for cheap, it's the easiest to go wrong.

I don't know if there is any other way besides what I said.
