The Protecting AR App allows you to observe various types of shutters projected in real time through the rear camera of your smartphone directly on the screen, so you can check which type of shutter is most suitable for your windows. Just allow access to the rear camera of your device to be able to use the App which, through augmented reality, will show the shutter on the screen in real time just as if it were in front of your eyes. We recommend that you always update the application when required, we are providing for the insertion of new shutters and of course the resolution of any bugs.
