Ring 2 detection range

Hi Marley. I purchased one of the Chime Pros after talking to tech support and my RSSI is 43-45 now. They said the camera appeared fine. I’m still having problems with motion detection. It will not detect a person walking up my sidewalk until they are around 3 feet from the camera. It will sometimes detect a cat out around 14 feet. Has no problems detecting cars 40-50 ft out

I’ve attached a photo of the curent view. I’ve experimented with the sensitivity settings using the street and no street but nothing seems to really effect it. The green plant on he left is 14 ft away from the camera and it will not pick up person there even if they are walking at a 90 degree angle to the camera. I’ve seen lots of videos with these cameras mounted in similar conditions that work fine. I’m really at wits end. Any thoughts would be greatly appreciated. Thanks
