Floodlight will not adjust properly

I got a wyze floodlight and am extremely disappointed. It turns on whenever a vehicle goes by approx 30 ft away. It will not turn on when I drive up about 20 ft away. I have to walk in the dark until I get 12 ft away at a certain angle. I’ve adjusted the settings over a period of five months and it seems to be arbitrary. My previous 25 year old floodlight worked perfectly.
