First, find the weak points in the perimeter. Study patrol logs, note the times the cameras are blind, and map a corridor that stays out of sight. Use a small, silent device to jam the nearest camera for a minute, then move before the cycle restarts. Plan each step on a 15‑minute cadence, with a backup exit that follows the same logic. For the cover, dress as a maintenance technician, carry a toolbox with a pre‑written log entry that explains the “repair” you’re doing. Have a pre‑written note for the security guard that explains a scheduled power outage; that way the guard has a reason to look at you, not the other way around. The key is to keep the story short, believable, and rehearsed until it feels natural.
