Direct answer • Security planning
How should security cameras and networks be protected from surges?
Use a layered strategy: facility-level protection, correctly grounded electrical service, point-of-use protection, UPS backup and protection for exposed copper data or PoE lines. Fiber can reduce conductive pathways between buildings, but equipment power and terminations still require planning.

A surge can enter through utility power, outdoor copper, gates, poles, inter-building links or grounding differences. Protection must follow the actual pathways.
What a UPS does
A UPS provides short-term runtime and cleaner shutdown or ride-through. It does not replace grounding, bonding or surge protection.
Coastal inspection matters
Protection devices are sacrificial. After significant events, systems should be inspected and failed protection replaced rather than assumed functional.
