Abstract
A coated article is provided for use in a surveillance window or the like. The coated article is a second surface one-way mirror that allows an observer(s) on an observer side to be able to see an object(s)/subject(s) on the opposite side of the coated article, but a viewer on the opposite side cannot reasonably see through the coated article to view things on the observer side of the coated article. The second surface mirror is designed to have a high glass side visible reflectance (RY), and an extremely low film side visible reflectance (RY), so that visible transmission (Tor TY) of the coated article is lower than the glass side visible reflectance but higher than the film side visible reflectance.
