Delay for actual motion yet so many false alerts

Bought the Video doorbell 2 ( the $ 200 one ), worked horrible despite my router being only 25-30 feet away. Bought the chime pro- now get RSSI of -44 on average.Lately getting ton of false alerts both at night and day- no wind, cars, nothing !When there is motion in the set zones, it takes too long to detect and the image typically starts of cloudy or distorted. Example- delivery man last night- sidewalk leading straight up to front door is about 15 feet and then porch another 10 feet- did not pick him up until he was actually bending down at front door to drop package. No he was not that fast, in fact, he was taking him time so much that he didnt exit the camera view until around 22 seconds into video ! Had he jogged or even walked fast he could have easily gotten to front door without any detection at all so what is point of this camera ? 200 for doorbell was too much, then another 50 just so it would work half way- criminal !Pic 1 below - camera shows Zero seconds into video. Pic two was 22 seconds in. RING should include a yard sign with its products asking criminals to please walk very slowly so the ineffective cameras can attempt to capture their movement and image.
