Requesting assistance - Surge and Lightning Protection for Networks

[XL1000]

We have 4 X Buildings, the main building is on one side of a tar road and the other three buildings are on the other side of the road.
ISP is at the 1st building and I bridge to one of the other buildings by Nano 5AC LOCO Unifi

In building 1 we have the fiber ONT, Unifi Security Gateway Pro 4, Unifi 8 Port Gigabit PoE switch running the AP's and LAN (VOX 1000/200 on Vumatel)
Bridge to 2nd Building
In building 2 we have 2 X 8 Port Unifi Gigabit PoE switches, 2 X HP Gen 8 Microservers, 2 X AC AP LR, several PC's connected via LAN.
Bridge to building 3 is via Aerial Ethernet Cable
In building 3 we have 1 X Unifi 8 Port Gigabit PoE Switch to 2 X AC-AP-LR and a few LAN devices like printers and 1 X AC-AP-LR deployed in building 4 via Ethernet from PoE Switch in building 3.

So we are in Helderkruin and our stands are particularly attractive to lightning and we also have the usual load shedding up to three times a day.
Every day I get to work I have to plug in all the hardware and connect the ethernet cables to the switches, servers, and printers (Staff do their own desktop PC's)
This I have to do in three of the buildings because if I don't and we have lightning, we lose almost everything. Today I am having to install three new alarm panels and various PIR and beams that have neen damaged by lightning. Insurance no longer wants to cover us.

This open and close every day is driving me nuts. Is there a feasible way to protect the equipment without having to disconnect every day?
Any advice would be greatly appreciated.

You do get rj45 type lightning / surge protectors. Ubiquiti makes 1 which I’m about to order for myself.

However, a direct lightning hit is very unpredictable. Sometimes even the protectors are not enough to keep equipment safe so for our stormy months, it’s safer to disconnect.

Regarding the power lines, there are surge protectors that for into the DB thst can be used. Again though, a direct lightning hit to the building changes things a bit.

You install a lightning rod in the tallest building for the lightning. Battery backup inverter for the load shedding and power surge.

How are all your buildings connected?
If via copper, then that is a major problem.
You should rather look at fibre between the buildings.

Lightning rods with proper gounds on all buildings is also a requirement.

You need to get the copper out of the group, well for your network at least.
