When going on a business trip or traveling, most people will need to rent a motel or hotel room to rest. Many people have the habit of checking in and immediately resting, not paying attention to their surroundings. However, this is a mistake. After checking in, you should check to see if there is anything unusual in the room.
Two-way mirror
Mirrors in hotel rooms are usually one-way mirrors. However, you should still check all mirrors carefully to avoid encountering two-way mirror problems. Two-way mirrors allow people to observe the image in the room from the other end or install a video camera behind them without our knowledge.
A two-way mirror will have different image reflections than a one-way mirror. With two-way type, the person standing in front of the mirror can see their reflection just like using a normal mirror, but the other side can observe us easily.
