Floodlights not coming on with motion

I have Ring Floodlight security camera and having an issue in floodlights turning on with motion. The lights are coming only when motion is few feet (4 to 5) away. Any motion further doesn't turn light on. I know there is motion setting and that is already set to max. The camera angle is also good. Is anyone else experienced this kind of issue? This is my replacement camera. In my previous camera light motion sensor was working absolutely fine and detecting motion even 5 meters away. But that camera had pink picture issue so I got replacement from ring but now this new camera has light motion issue. This is really frustrating that since I have Ring camera there is one or other issues.
