What kind of mirror do you see when staying in a hotel?

When staying in a strange environment such as a hotel, you must be vigilant, especially for girls! In fact, besides avoiding going in and out alone, we should pay special attention to the mirror on the wall. Why do you say that?

Because there have been double-sided camera shots in hotels, guesthouses and other places! !

does it sound complicated? What the hell is that double mirror?

The double-sided mirror was originally used as an indoor floor-to-ceiling window or glass curtain wall to protect privacy (the mirror faces outwards, so the room can't be seen outside), but it was used by criminals. Simply put, criminals can see the inside of the mirror through a double mirror.

how to identify a double mirror?

1 finger judgment method

One finger can try! It's simple. See if there is a distance between your finger and your finger in the mirror. Normal mirror, with a certain distance; Double mirrors, fingertips are seamlessly connected.

principle: because the common mirror is a glass with a reflective layer in front, and the reflective layer is generally plated on the back surface, it is separated by the thickness of a piece of glass.

Leak: If a layer of glass is placed in front of the double mirror, or the coating is a "sandwich" in the middle of the glass, this method will not work.

2 method for judging brightness

A double mirror uses about 5%~7% reflective layer, so it is darker than ordinary mirrors. Take out the cosmetic mirror you carry with you and compare it together to see if there is a big difference in brightness.

Disadvantages: This method is easy to misjudge, and there may be color difference between mirrors.

3 "the enemy is clear and I am dark" method

A double mirror has a special feature, that is, it can see the bright side from the dark side. Therefore, if you turn off the lights on your side, you will see the opposite scene (provided that there is a certain brightness on the opposite side).

what if the peeping Tom is hiding in the dark?

Hold your hands against the mirror to form a "telescope", cover all the light sources, and keep your eyes close to the "telescope". As long as there is a little brightness on the opposite side, you can see it.

When you encounter a suspicious mirror, I believe you can have a correct judgment by combining the above three methods.

In addition, for the convenience of observation, the back of the double-sided mirror used for peeping is usually empty. So, you can also tap the mirror and listen to the sound. If the cavity echoes slightly, be careful.

In the future, I will stay in a hotel and make a floor, instead of taking a shower, I will use my own toothbrush cup and not change clothes. When I sleep, I will turn on the air conditioner and wrap myself in a quilt. Afraid!
