There is a very ingenious product called RING, which is a very distinctive doorbell, that calls your cell phone & allows you to see who's there & communicate with them. The commercial shows a would be burglar ringing the bell & the homeowner from the beach has a conversation with the burglar that sends the burglar looking for an empty house.
Now in a perfect world, burglars would not watch TV & would be thwarted by this product. In the real world, burglars watch TV & are probably very alert to anything that pertains to their profession. A burglar that had seen this commercial would simply knock on the door to confirm that the house was empty, thereby making this product sort of useless.
I'm reminded of another product that was made useless by advertising it. Galco several years ago came up with this very distinctive fanny pack that you could carry your handgun in without attracting anyone's attention. They then put full page ads in Guns & Ammo. This magazine is viewed by normal citizens & bad guys & police. So anyone that has an interest in guns would notice the fanny pack & know you were carrying thus defeating the whole purpose.
