Is there any electrical engineer out there? Ask about the indoor exit outdoor wiring system issues.

Just I want to install a Hikvision ball camera on the rooftop of my self-built house, and the nearest power outlet is in the third floor's electrical box, because it's an outdoor line and also on the rooftop, so I'm particularly concerned about the safety of the ordinary lines inside the electrical box in the third floor. I think maybe I should install a surge protector or other electric components that can ensure that if the outside cable breaks, it won't affect the safety of the indoor ordinary cables.
