Ikelite Underwater camera housing with Hydro-Wiper
Just one example of a custom Hydro-Wiper design- This one for an Ikelite housing.

Underwater cam?  Hydro-Wipers help capture better images underwater for longer:

Beneath the waves, there is a whole new world to view… don’t let your vision be obscured by bio-fouling.

Increasingly, researchers are turning to the use of underwater cameras to record changes and observe habitats underwater. Zebra-Tech is often asked about antifouling solutions for underwater camera housings. The same rugged technology we use to keep sensors clear can also be applied to a wide range of underwater camera housings.

Recent designs include versions to fit GoPro housings such as the Scout and the I Pix. Another, the Ikelite housing features a longer arm to wipe the larger housing. Please talk to our design team if you have a camera housing in mind and we can check to see if it will suit a custom Hydro-Wiper.

Hydro-Wipers are either self-contained units with their own battery and controller, or units which can be externally controlled – for more information please check our Hydro-Wiper page.

Fittings and clamps, extended deployment housings, unusual wipe angles…. Zebra-Tech’s in house machining facilities and design teams are constantly challenged to innovate. Providing solutions to data collection beneath the waves.
