I just purchased a Tapo C425 Smart Camera (HW Version 1.6) and have updated firmware to the latest (1.2.13).

it is installed and running.  I have turned on motion detection and set the detection zone so that it does not include the street.  

In the photo you can see a screenshot of the passing golf cart that triggered motion detection. Below that is another screenshot that shows the motion detection zone that is in effect. As you can see, the golf cart is well outside the detection zone!
 

I am on a busy street, and every passing vehicle is creating a motion event!.  Is there a fix for this problem?  I am hoping that something can resolve this because the device will not meet my needs if the detection zones are nonfun
