There is probably a hole cut into the wall there.
If you want an innocent explanation, then it’s entirely possible that there used to be a medicine-cabinet-style mirror there. It looks like it’s about that size and would fit in that location. Those medicine cabinets are recessed into the wall and so they require a hole to be cut in the wall. When they installed the large mirror, they didn’t think it was worth it to repair the hole, since they were covering it up with a mirror.
If the hotel is fairly old, it might have had something like that in the past.
But since there is no way of knowing that for sure, if I was in that room, I’d assume there’s a camera behind there, too.
Some hotels just put a hydrophilic coating on their mirrors. https://fsicti.com/markets/architectural-building/bathroom-mirror-shower-door/
Even so, there is no reason to downvote my comment. It is possible for there to be a hole there. Voting like that just makes you an asshole. And, yes, comment votes are public information.
This will never not be the saddest shit on this website, please go touch grass.
Alternatively, you can go fuck off instead. People who downvote and then reply to the comment as if they want to have a discussion are a fucking cancer.
How can you tell who downvoted you?
One way to tell is https://lemvotes.org/
On the one hand that’s interesting; on the other hand that could drive me nuts…
Votes on Lemmy are public, mods have easy access afaik but there are sites that let anyone see who voted what on any given post or comment.
Sorry it took me 12 days to respond, I was taking a break from Lemmy (you should consider it) but I just wanted to pop back in and say lol downvoted.
These are such a good idea. It works by having a heater behind the mirror which prevents the condensation.
Maybe somebody’s stashing delicious freshly baked goods back there?
There are coatings /sprays for this
I think in this particular case it might be an integrated heating element like this: https://clearmirror.com/products/shower-clearmirror
They’re popular in shower rooms in Japan.

A gee, thanks.
You can also just rub some shaving cream on it and wipe it off.
Or soap
Or rain-x anti-fog or similar coating to achieve the same.
Or a secret room behind the mirror at a warmer temperature
Oh high neighbors! No, no, I’m not shaving the car again! This is so it doesn’t fog!
This reminds me of something I heard on the radio a million years ago:

Here’s Click and Clack from the Car Talk radio show
Putting this show on is so bittersweet. I miss this from my upbringing and these two guys were so great; I was genuinely sad when I heard one of them had passed
I’ll try to get the timestamp for the relevant part, but the title of the episode hopefully gives a hint and it’s worth listening to it in the entirety anyways
Edit: alright, the timestamp is 31:50!
Edit 2: I forgot to include who it is
I just woke up. Is that click and clack the tappet brothers?
Yes!!! I love those guys
I grew up with my family listening to NPR so some of my fondest memories are getting up to my parents or grandparents making breakfast with that on, or any other of their wonderful shows
Would make for a great practical joke.

These are such a good idea. It works by having a mirror behind the heater which prevents the reflection.

Alright, but now the heater is in the way.
Yeah, that’s why it prevents the reflection
Uhh, 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?
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
are you severely low on blood sugar or something?
I 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.
Edit: Turns out this is incorrect; thanks to everyone for educating me!
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
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.
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.
You 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.
༼ ͡ಠ ͜ʖ ͡ಠ ༽
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.
This 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.
Another tip was shining a bright light to illuminate the supposedly dark room on the other side, which again, would be way more expensive than a smoke detector spy camera.
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.
Ahh yes, because that would produce exactly square shaped heat.
It a very big Pi. Might even be a Tau.
Dumbass, tau is round
What about taumoeba?
Then why are people talking about squaring the circle
Why else would it be called the inverse square law?
- Gets rid of fog
- is in shape of a square
Makes sense to me!
Lol, when I cut a hole in the wall I always make it the exact shape of a raspberry pi
Not with that attitude!
well. at least my viewers will know it had a flared base.
it’s all good some people like a hairy dude
Ah yes, 10W of heat :3

Your part of a TV show!
It’s heated.
Just posting to say I was here when everyone replied with “These are such a good idea. It works by having a heater behind the mirror which prevents the condensation.”
Hahaha I just saw this. fedia.io was having a moment and posted my comment several times and everyone else has just run with it. Quality!
This comments section feels like schizophrenia.

Wait until someone finds a screwdriver.
that’s the two-way section
It’s a two-way mirror and there’s a camera on the other side recording you 24/7.
jokes on them, I’m already pornhub famous.
Nice butthole!
Hit me with them links bruh

Not gonna beat it to ya, just curious 😆
Isn’t a two-way mirror just a window? I think you meant “one way mirror.”
No. English is just hella stupid. 🤣
A one-way mirror, also called two-way mirror…
How many ways is a normal mirror, then? Do we call it a “no way mirror”?
wouldn’t a one-way mirror only be used “one way” and a two-way mirror be used in “two ways”?
While a no-way mirror is a mirror owned by a vampire.
Well I mean dictionaries. Kind of like how webster defines literally with
Definition 1: In a literal manner such as …
Definition 2: used in an exaggerated way to emphasize a statement or description that is not literally true or possible.
A one-way mirror is only one-way when the lighting conditions are correct. Otherwise you can see right through it from both sides
Both terms are used
It’s heated.
I had this happen in a hotel, and being curious I removed the mirror, and yes there was a hole in the wall behind it, no there wasn’t a camera there. It was just were they had ran the wiring for the lights on the mirror.
It would make sense that it serves like an access hatch to a terminal block that feeds the whole room. It’s simple, costs nothing, is easy to get to (compared to having it sealed in the wall), protected from splashing and prying guests, and close to where you want most lights and outlets.

protected from […] prying guests,Nothing is protected from those willing to pry hard enough ;)
In the olden days, I personally freed many an alarm clock that were non rotateable and tv remotes with short cords. The worst was on screwed into a swivel on the dresser the TV was on.
