Multiple RING Alarms, single property

Hi, I have an existing RING alarm and siren on a detached garage conversion at my property. The main house alarm is old and having experienced RING for the garage would like to also have a matching RING system and siren for the main house property. It looks like RING can cope with multiple locations - I saw an article that suggested this isn't possible however what are the issues of just buying another RING Alarm, base station etc. as if my neighbour bought one? Would I need to subscribe to several RING protect plans? Is there an issue with the Z Wave network or whatever it uses where over closer distances (same property) the two ALARM base stations and sensors would clash? I can't imagine so otherwise someone with a small property would not be able to have a neighbour who bought one?! Any advice on this would be much appreciated. Regards, Paul
