Your example of camera in the living room
(1) Event is captured by someone leaving the living room but no recording of that person entering the living room.
(2) Both Amazon cam and Blink cam records both, But the Wyze does not.
Guessing here: when the Amazon & Blink cams are fighting for air time to record the same event, the Wyze cam loses out. You could try putting Amazon & Blink to sleep awhile and try again.
As for the contact, motion etc. There is a lot going on there, too difficult for my pea sized brain to diagnose. Might you also have a WiFi sniffer to map the traffic?
