Doorbell Extra Motion sensitivity settings - object size

Extra Motion sensitivity settings - object size. My doorbell faces a London street with my small front garden. It’s impossible to use zones effectively as the area is complicated, and positioning the control points is needlessly restrictive (you can’t get them close together). So lowest sensitivity is the only setting I can realistically use, but it still picks up a small speck of a person over the road. The latest doorbell wired doesn’t have lidar I know but it’s simple geometry that someone needs to be quite big to be close to my door. Allowing removal of small objects (rather than just sensitivity) would help a lot I think.
