Double Sided Window Decal Sticker Security Stickers are one sure fire deterrent that work! Law enforcement and security professionals will tell you that criminals are opportunists looking for an easy target. Sometimes the simplest of ideas, such as warning decals or lighting, can deter a crime. Our security decals are two-sided, so they can be installed on the inside or outside of your doors or windows and are easily readable from both sides.
