How to avoid image distortion due to the ponding water on the ClearSight dome cover

Last update: March, 2021

This article describes how to avoid image distortion due to the ponding water on the ClearSight dome cover.

Issue 

The multi-sensor cameras have poor visibility at the bottom in the rain.

 

Cause

Water is ponding at the bottom of the dome. This is caused by ClearSight coating.

 

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

 

Difference in vision without ponding water

Difference between Tilt angle 0 deg and 10 deg
