Surveillance Detection Routes (SDR)

Surveillance Detection Routes (SDR) constitute a specialized counter-surveillance methodology utilized within executive protection, intelligence, and high-risk physical security operations. An SDR is a meticulously planned and executed sequence of movements—often vehicular, but applicable to pedestrian transit—designed to isolate, identify, and confirm the presence of hostile surveillance without alerting the adversary. This is achieved through strategic maneuvers such as stair-stepping, channelization, utilizing choke points, and executing deliberate timing changes. By forcing a follower into unnatural traffic patterns or exposing them in controlled environments, security professionals can assess threat levels and initiate evasion or tactical response protocols, safeguarding high-net-worth individuals, corporate assets, or sensitive personnel.
