Ring should have an outdoor alarm siren that lights up . Because it’s alright having an alarm inside but if a burglar doesn’t know there is an alarm system inside . they will break either window or door .so then you have to buy a new window or new door . Where as in if the ring system has an outdoor siren that lights up .it warns burglars that there is an alarm system so burglars are less likely to break in the house . There’s plenty of z wave outdoor sirens about but if ring had there own it would also advertise ring aswell .
