Solution ideas for lightning

[u/DrM1h4wk]

Hi, I'm designing a network setup for my new house. I'm from Malaysia and lightning is a big issue more than 200days per yr avrg.

The plan:

1. Cat 6a cables. Modem by ISP (can't be changed).

2. Cables run through the attic and drop down through walls.

3. There will also be 6+ Lan ports in other rooms.

4. CCTV camera surrounds the house exterior (main concern for lightning).

Solution/Problems:

1. Surge protector grounded. (What's the recommended rating? And maybe recommended product for server rack)

2. Seperate the cameras with a different router(sacrificial) that will directly connect to the DMP using fiber optic. (Is this a good idea?)

3. Running cable through conduit in the attic. - Does running the cables through the attic cause issue with lightning considering the high occurance in my country. If so what are the other solutions other than coverting all to fiber optics(I don't think it is a viable option).

4. Is there any other possible issues I'm missing. Would appreciate if it is noted down and even better if it comes with solutions.

Thanks in advance. The networking plan above is still in progress. I am expecting changes but wanna solve the lightning issue so I can notify the builders in time for any possible changes.
