The IP65-rated OAK-D Pro W PoE camera is designed to withstand harsh environments, including dust and water jets from any direction. However, it's not rated for immersion in water or exposure to corrosive substances like seawater or harsh cleaning solutions.
The IP code of a device tells you whether it's dustproof and/or waterproof. An IP65 rating means the device is dust-tight and protected against water projected from a nozzle. It does not guarantee protection against immersion or corrosive substances.
If you need a camera that can withstand immersion in water, you might want to consider the IP67-rated PoE devices like the OAK-D-POE and OAK-1-POE. An IP67 rating means the device is dust-tight and can withstand water immersion between 15 centimeters and 1 meter in depth.
However, please note that even with an IP67 rating, the device may not be fully protected against corrosive substances like seawater or harsh cleaning solutions.
Also, when installing the camera, make sure that the GORE vent isn't blocked, as it can lead to moisture fogging up in front of the cameras (on the inside of the front cover).
TLDR: The only way to know is to actually test it out which is what we'd recommend that you try doing and we'd love to hear feedback on how well it holds up.
