Fedex delivery - ring stops recording within 20ft

Everytime a fedex delivery guy comes about 20ft near the home the ring video stops

Why is this happening

I tried motion detect only i tried smart alerts

No problems
Capturing my neighbors and the children playing but as soon as FedEx arrives and the young man approaches 20ft before my door all video stops and resumes when the truck is driving off

Here is the attached video you can see for yourself. Its always fedex for me

Here is the fedex truck leaving
