PSARA: The Private Security Agencies (Regulation) Act, 2005 — India's law requiring security agencies to hold a state licence, verify and train guards, and follow deployment standards. Always ask an agency for its PSARA licence number.
Controlling Authority: The officer or body each state designates to issue and enforce PSARA licences — handling applications, renewals, inspections and cancellations.
PSO (Personal Security Officer): A trained close-protection professional assigned to an individual — covering threat assessment, route planning, travel security and emergency extraction. Distinct from a site guard.
Bouncer: Entry and floor-control personnel for clubs, parties and events — handling ID checks, capacity discipline, de-escalation and safe dispersal.
HHMD / DFMD: Hand-Held and Door-Frame Metal Detectors — frisking equipment operated by trained guards at managed entry lanes for events, venues and facilities.
SOP (Standard Operating Procedure): The written post orders governing a deployment: duties, shift timings, patrol beats, escalation contacts and reporting formats.
Armed vs Unarmed Guard: Unarmed guards handle access, patrol and deterrence with training and supervision. Armed guards carry licensed weapons for high-risk sites — deployable only within licence terms after threat assessment.
Beat / Patrol Beat: The fixed route and schedule a guard walks during a shift, logged hourly. Beats convert wandering presence into verifiable coverage.
Reliever: The backup guard who covers a post during leave or absence so no position goes unmanned — deployed same-shift from the zone hub.
RWA: Resident Welfare Association — the elected body managing a housing society, typically the contracting party for society security deployments.
Access Control: Systems and procedures governing who enters where: badges, biometrics, visitor enrolment, material passes and after-hours permissions — operated with guard support.
Incident Report: The written record of any security event: what happened, when, who responded and what followed. The backbone of accountability and insurance claims.
