During the first month, you might get some. scOS is learning your property: who comes and goes, what's normal, what isn't. It asks questions when it's uncertain.
After that learning period, the goal is zero false alerts. Not low. Zero.
Most security systems drown you in notifications until you start ignoring them. That defeats the entire purpose. When you get an alert from scOS, it should mean something. Otherwise, what's the point?
