Can anyone recommend a camera that is up to the task of being on the water with salt air?

Clients want cameras installed, 2 facing the ocean, the other 2 facing the front of the house which is not in direct contact of the salt breeze.

To give you an idea, we installed 6 deftech outdoor speakers last summer and we are replacing them in a few weeks since the salt "ate" them.

Obviously it is just a harsh environment and will probably need to be replaced every other year anyway. Also ive pre-wired it for both IP cams and analog!

TIA
