WhatsHerBucketThis section of mirror doesn't fog
half_built_pyramidsUhh, because of the heat of the raspberry pi & camera behind there
Suppose you were in this situation and suspected something. I’d imagine the space behind it would be totally dark, so what would be a safe way to check if there’s a gap in between without breaking the glass?
GuyFawkesI read a long time ago that putting something flat against the mirror will show you. I think if the mirror is legit you’ll see the reflection directly on the surface, if it’s two way the reflection will look like it’s inside the glass.
But I’ve never had the chance to actually test that, so take it with a grain of salt.
Dr. WeskerYou want there to appear a “space” between your fingertip and the mirror, if touching it directly. If there’s no space, then say cheese.
If you’re touching, someone’s watching.
Then I’m touching hard and often
Then I’m watching intently and always.

Surely you could just put another sheet of clear glass on your one-way to avoid this though? Wouldn’t want someone to accidentally scratch the coating and reveal the whole thing anyway
If they’re going through that much trouble, they deserve to see me whackin it.
TeamAssimilationThis is ancient advice for two-way mirrors, IIRC nowadays even legit mirrors can reflect directly from the front instead of the back. In this age of spy cameras this is mostly irrelevant.
Yes, darkening your room and then pushing a bright light up against the one-way, taking care to not have it leak into your room, should make the other room brighter so you can see it.
Not that this is a one-way mirror anyway.
It would be the other way around, if at all.
"First-surface" mirrors where the reflective layer is on the front of the glass are quite fragile, so wouldn't typically used for residential applications (you'd remove the reflective coating by cleaning it).
A regular mirror has the reflective surface on the back of the glass (which is then is further coated with a protective paint), leading to the effect you describe.
I don't however know enough to say one way or the other whether a surveillance mirror would becessarily be a first-surface mirror.
Just checked my bathroom mirror and it looks to be a first-surface mirror

scientific use mirrors are front mirrors, the metal is deposited on the outer surface. They are delicate and difficult to clean.
Every household mirror is rear coated, and then painted to protect the metal from oxidation.
there are no “one-way” mirrors. You just need to make your side darker than the other side (there’s a reason the observation side of a two-way mirror is never brightly lit, but the interrogation room is)
Tldr: put your face right up against it and use your hands to block out as much light as you can

15 upvotes? Really? Mirrors are painted on the back with opaque paint.
Are we cross posting this to a flat earth science forum?
but a one-way mirror (also known as a two-way mirror) is one that you can see through in one direction
