I wonder if the product will deter burglary. If you look at it closely, it won't take long to see it as a decent looking fake. At a certain distance, it might be useful to fool random vandals. Its size is rather smaller than expected. The decal came with the product was all crumpled, cheaply made with sticky side on the back, forcing me to put a masking tape to display inside the window. I am still wondering if I am going to use it outside or indoors easily visible from outside.
