In the tumultuous times of 2021, you can never be too careful about your personal safety. Big cities are constantly under threat of attack, but you could be vulnerable in your everyday life as well. In the past years, more and more people have found themselves the victim of a two way mirror.

Two-way mirrors are designed to be undetectable and used for police/detective work. Unfortunately, criminals have taken these well-intended devices and used them to their advantage. How do you know if you’re one of these unsuspecting victims?

Thankfully there are a few ways to tell. Read on below to stay safe!

How to Identify a Two Way Mirror

The Finger Test

The way regular mirrors are constructed is different than a two-way mirror. With a household mirror, the silver is painted/applied behind the glass at the back of the frame.

With a two-way mirror, it’s the opposite. Two way mirrors are essentially very tinted windows.

The construction differences allow you to identify which mirror is which. When you’re suspicious about a mirror’s integrity, place your finger onto the glass in a pointing position. If there appears to be a gap between your fingertip and the glass, it’s a one-way mirror and you’re safe.

If the reflection of your fingertip touches the real finger, it’s likely a two way mirror and you need to perform another test to make sure.

Location Location Location

Like in real estate, the location of a potential double mirror determines it’s “value” to criminals. Think about where the mirror is in relation to the rest of the house/building.

For example, a mirror in your hotel room bathroom on a wall that faces the interior of the room doesn’t have space for a viewing area.

On the other hand, public dressing rooms that have mirrored walls and an unknown architectural structure would be worth checking. For a double way mirror to work, there needs to be space enough behind it for people to watch.

Tap Test

Since there needs to be a space at the back of the mirror for criminals or peeping toms, double mirrors will sound hollow.

If you suspect you’re being watched, tap on the glass and listen to the sound. If you can hear a hollow reverberating sound, there’s a chance it’s a two-way mirror.

Lighting

The way two-way mirrors work requires the light on the reflective side to be much brighter than a normal room. This is because two-way mirrors work much like tinted windows.

For example, if a house has its lights on and it’s dark outside, it’s easier to see in vs when the lights are off.

What to do if You Suspect Foul Play

If you’ve performed the tests above and you think you’re dealing with a two-way mirror, leave as soon as possible. Get out of the mirror’s view and make sure to note its exact location. Call or visit the police and let them know your suspicions.

Tell them the tests you completed and the mirror’s exact location. They’ll handle it from there.
