Person Detected versus Motion Detected

Hello. I have a Indoor Ring Camera. There is no-one in the room, however the Ring Camera notifies me of a "person detected". What is the difference between Motion detected and Person Detected?I also get a lot of "Motion Detected" during the day in the 2 darker rooms of my house - false alarms. I have tried different sensitity levels, night color vision on/off, infrared on/off, zones, etc.. but still get occasional triggers. It may be due to external sun light changing (e.g. clouds) - but what settings do i need to change to mitigate this problem?Help. Thanks!
