Countermeasure
Change the tilt angle to avoid affect by the ponding water.
[Case of multi-sensor camera]
WV-X8570N: tilt 10 degree (2 notches), WV-S8530N: tilt 15 degree (3 notches)
WV-X8571N:tilt 10 degree (4 notches), WV-S8531N:tilt 15 degree (6 notches)

Difference in vision with ponding water
Difference between Tilt angle 0 deg and 10 deg
