@sdetweil Where can i find 2 way security glass?

@sdetweil Inside smartglass opens on inside of guest bathroom and looks into the hallway trough the two way. Still looking into the smartglass premade vs film. Obviously i do not want people to see trough the two way into the guest bathroom.

Not sure if this is the right forum, but I have the following plan I am trying to realize.
I have a guest bathroom in the entrance hallway in my house.
My plan is to put a full length 2 way mirror(roughly 30x72) towards the hallway, and then have a smartglass on the inside of the guest bathroom. Put a “do not touch” button on the inside of the guest bathroom, that once pressed, opens the smartglass so you can see straight into the hallway.
Has anybody done something similar, and can give me some tips?
I was thinking of building a 2X4 frame to insert in the wall. Paint it black on the inside and glue the smarglass and 2 way mirror into this frame before I attach some crowning around it. both will be recessed to flush inside the frame.
Any thoughts?
