Security window films are installed like window tint, but are designed to keep your window intact even after being shattered by impact. They can add significant effort for a thief attempting to break in to your car, potentially causing them to give up. An important consideration before installing, is that it could hinder your ability to escape if your vehicle was submerged or in a similar situation where escape through a window is required. However, most cars now have laminated windows in the front and would already be difficult to escape from. This is why you see many thieves breaking in from rear windows, as they are tempered glass, which is harder but shatters into tiny pieces when broken.
