Why should you wait until someone breaks the window of your home? Your
Vigilant Window can scare the heck out of burglars, so they'll never
know what hit them, and probably never think of coming back!
If you've been thinking of getting a security system, or you have one that
doesn't provide you with enough security... you should know about what is
coming down the pike. A large German innovator and manufacturer, Fraunhofer-Gesellschaft, has invented a way to turn any window or
glass door into a motion detector.
The company created a fluorescent coating that contains nanoparticles that
convert light into fluorescent radiation. Once this coating is placed on the
window, an invisible light is directed at the window. This light is directed to the edges of the
window, where it is illuminated. The software for the Vigilant Windows system
has been refined to differentiate the invisible UV light from passing car
lights and street and property lights.

The light frame created at the edges of the window acts as a light
barrier. If anything steps in front of it, there will be less light in
that area and the sensors can determine its approximate size, the direction it
is moving, and how fast it is moving. You may not know who it is, as the
Vigilant Window system images are more like an x-ray than a photo, but you will
know whether your intruder is a person or a bird or raccoon. And you can set
your alarm threshold so that small animals will not trigger the alarm.
The research team at Fraunhofer-Gesellschaft is doing the final tweaking of its
invention, getting ready to produce and market it. You will be able to spray
the fluorescent coat on your windows or cover them with a thin florescent film.
It will be interesting if the Vigilant Window makes a good dent in
the industrial and home security market; there hasn't been much innovation in
this area for awhile.
