You know, like in the interrogation rooms in detective shows. How do they work?

One type uses a very thin layer of aluminium which combined with the glass refelects one way and transmits the other way. 

Another type has tiny holes in the reflective surface which is only reflective on one side.  Looking one way you see though the holes.  They other way you are 'blinded' by the reflection and don't see through.


Both require suitable lighting conditions on both sides.   

I suppose such mirrors are more expensive than cameras these days.
