Doorbell stops detecting

kpb

Hi.

Ok I think I found quite a disturbing issue with the doorbell person detection, I would like to share with the audience here to verify or keep an eye on it.

It seems that the person detection suddenly stops after a certain period of time. I experienced this 4 times now as I could double check with a 510A on the same location. The doorbell was not able to detect a postman walking right up in front of it between 0-7 meters, full sensibility. After a restart,.the detection worked again.
The doorbell itself still works, shows a live picture and all. But all person detection stops.

Please report if you have experienced something similar or if it is an individual problem.
