Night vision means that the film is dual reflective.
During the day reflective window films look like a mirror as the sunlight bounces off of the glass surface.
One way mirror film can be installed on your windows to create maximum privacy during the day and prevents the fish bowl effect of the window film reversing the reflectivity back into your house at night.
However that s not the case at night.
And while many products offer plenty of privacy and enhanced security by day we recommend installing privacy window film designed to work at night too.

The outside surface is reflective to keep out the heat and the inside is not so you can clearly see out day or night.
