Ring Outdoor Siren?

How is it possible that a company that specializes in alarm systems, doesn't have a product that is central to the effectiveness of alarm systems; a loud outdoor siren? It seems like pretty low-hanging fruit to develop such a product so I'm wondering why Ring has chosen not to do so. I live in the the Catskills (upstate NY) and my neighbors aren't close enough that they would hear the internal siren. While I appreciate every other aspect of the ring system, I'm considering moving to another brand that has outdoor sirens.
