If you could buy a home security sticker without the actual security sysem would you?

If I were a home invader, seeing a sticker on the outside would probably make me think twice about going any further. So if these stickers were widely available the criminal wouldn’t know if there was really a security system there or not. While having the actual security system guarantees some things, just having the sticker would stop a criminal 9 times out of 10, so would you pay $20 for just the sticker?
