Personnel Protection in stationary objects is about surrounding protected personnel with Protection Rings.
Security Personnel protects 24h/day, preventing access to Protected Personnel, securing from attacks.
Everything is to be planned & orders have to be precisely, meticulously executed according to the Plan.
Stationary Object has to be described precisely, for Security to be planned well enough.
i think but am no expert - that computers, cameras & other electromechanical equipment can be useful in forming Security Rings, that can be layered & combined with Protections offered by Security Team(s), perhaps. i think that Protected People's opinion is important in whether to allow these tools at all & to what extent.
(to be elaborated if/as i can).
