Introduce alerts based on a configurable timer [Time t a person stays in the vision of the camera]

Need a feature where the alert will trigger only if someone is in front of the camera’s vision for a certain amount of time, which could be configurable, say 15 seconds to a minute or so.

I have a Ring doorbell and my door faces the street. Even with the minimum sensitivity settings, all that I get are false alarms with people passing by since all the neighbors share the same front walk. Having time as a way to identify, is someone is lurking in front of your home will eliminate all those false alarms.
