External our Outdoor Siren for Ring Alarm

When are Ring bringing out an external siren box for the alarm system? Having an obvious and clearly visible siren box on the outside of a property is a big deterrent to any potential burglar, and deterring a break in is the primary reason for having any sort of security system. Using sirens to scare off burglars, and cameras to identify an assailants is great, but preventing the initial break in is far more important.
