ABSTRACT:
A security window has a non-transparent bullet resistant screen between the people on either side of the window. Because this screen cannot be seen through, an arrangement of mirrors (two on each side of the screen) is provided to reflect images from each side across to the other side. The customer and cashier each look into mirrors set at eye level on their respective sides of the screen and reflected images are directed to a point above the screen where two mirrors are arranged in a cavity. This cavity tends to act as a sounding box and permits sound to travel from one side of the screen to the other. The eye-level mirror on the cashier's side can be moved to a position where it merely reflects back the image reflected from the other side, in the event of an attack.
