I have motion detection enabled for people and for cars and have separate zones setup for each. I am constantly getting alerts for people but when I look at the video it's nearly always a car and is always way outside the detection zone.

I've made the zones smaller and smaller to try and stop this but it doesn't make any difference, I've set the sensitivity down to 2 and it's still the same, frankly if this is how the device works then it's essentially useless, I had a Ring in the same place and almost never got false motion alerts. I'm on the latest available firmware.

Here's a example of a person being detected

and here's the zone I've setup.

Really appreciate any advice as the next step is to bin this and find an alternative which is an expensive mistake to have made.
