Motion sensor setting off short alarm (3 secs) every time someone walks through the front door, regardless of the setting

Our ring base keeps blaring for 2-3 seconds everytime motion is detected on the motion sensor. So everytime someone goes in or out of the house, regardless of the setting - Home, Disarmed, etc - it goes off.It is really annoying and we can't figure out why it's doing it. Can someone please help?
