Marina Internet run

We have a Marina that needs Internet for security cameras. The main walkway is 1,200'. The ramp from land, Internet source, is 100'.
I think I should run a cable infrastructure, as opposed to wireless, since wireless has too much loss when repeating.
I think I want to use fiber patch cables (no termination hassle) up to 300'-500' since we have frequent lightening. I'm told copper and lightening are bad. Only the first 100' will be on land, the rest will be over water...maybe that can be copper but Fiber seems inexpensive.
I suspect I need to run the cables in Conduit, under the wooden walkway. But I wonder if I can get away with using outdoor/direct bury cabling.
Out of the 1,200' there will be maybe 8-10 cameras. Plan to use a Nema box at each camera. they will be mounted higher so no chance of water.
What are your thoughts on the materials I should use/avoid? Schedule 80 solid or flexible water tight?
The Marina walkway does go underwater a few times a year. There is electric under it too. I might be able to run the conduit higher so it never goes under, but then would be visible.

I’d run DB fiber and strap under dock or whatever it is and hurt to where it needs to come up than pvc conduit. Than media converter over to copper and POE cameras
 
Fiber would be the best, but Ubiquity makes enterprise class wireless that easily can go that distance without repeaters. They have one model that has a range of ten miles, line of sight.
 
What is DB Fiber? Direct Bury? So you are saying DB under the Dock to a central point (Hub). Then Conduit to the Cameras with Copper Ethernet cable. The most central ramp is about 100 meter from one end, 200 meter from the other (over the limit of copper ethernet).
As I research, the conduit (Schedule 80 was recommended) but is the most expensive part. I like DB.
Why not DB fiber to all the Cameras from the Hub as well, it is not nearly as expensive as Conduit. Do a Media converter at each camera? Can I do serial (daisy chain)? The last leg could be copper. Cheapo but at Amazon this comes in around $600, depending upon the number of cameras. much better, Sched 80 is almost $2k alone.
As for Ubiquity, I could do the same to the Hub on the Marina. Problem is, it is not line of site to both ends of the walkway, it is curved. So then we have hops. I guess I could DB to the point I can see the end, about 300 feet, the wireless. So a hybrid. hmmm

Yes DB I meant as direct burial. Only problem with taking fiber directly to the camera you will have to have power there for the media converter from fiber to copper won’t you?
 
There is a fiberoptic cable that also has a pair of wires in it for -48V, not sure i have seen any camera's the use it yet.
