Two Way Mirror Tricks

Move up to the mirror and place your fingertip or nail against it. If the reflection of your finger directly touches your finger, it is a two-way mirror. If there is about 1 centimeter of distance between your finger and the reflection, it is not.
Another way is turn the lights off in the room, then place a bright flashlight against the mirror surface. If there is a hidden chamber behind the mirror, the flashlight will illuminate it, and since you are in a darkened room, you will see the hidden room. Of course, any mirror hung in front of a wall will be a mirror and pane of glass installed into the wall, like any other window, will have window framing.


The recommended lighting ratio for surveillance purposes is 10:1, with the subject side being ten times brighter than the observer side.
