This document provides information on patrolling for security services. It discusses the objectives of patrolling, the different types of patrols (external, internal, route, general), how to organize and conduct patrols, preparation for patrols, what to observe and record during patrols, use of the senses, and expectations for patrol performance. Practical guidance is given for organizing patrols, conducting checks and duties, and preparing patrol reports. External patrols cover the facility perimeter and surroundings, while internal patrols ensure security inside buildings and machinery. General patrolling is done at the start and end of shifts and periodically to monitor security staff duties. Effective preparation, communication, observation, and documentation are emphasized for successful patrolling.
