front bumper sensor

I think I posted this before but can't find it. My front proximity sensor works but beeps seem only happen when it is yellow zone and front, but not the front corners until red, is this normal? The rear seems to be beeping as soon as they turn yellow.

Should beep on yellow. Could be a sensitivity thing with those sensors.
