Physical Security Technology Glossary: 50 Terms Every Commercial Buyer Should Know

Physical security technology has developed a specialized vocabulary that vendors use fluently and buyers encounter without definition. This glossary covers the 50 terms most relevant to commercial security buyers — defined accurately, without marketing inflation, and with the operational context that makes each term meaningful.

---

A–D

• Active monitoring: Security system monitoring where trained operators watch live feeds in real time and respond to alerts — as opposed to passive recording that is reviewed only after incidents are reported

• AI analytics / AI video analytics: Software that applies machine learning to camera feeds in real time to classify events (people, vehicles, behaviors) and filter genuine security events from false positives. Quality systems achieve 70–90% false alarm reduction.

• Alarm monitoring center: A facility that receives alarm signals and calls a pre-defined contact list — without visual information. Distinct from an RSOC, which monitors live video feeds.

• Autonomous patrol: Robotic or drone patrol that executes programmed routes without continuous human direction — the operator monitors feeds and responds to alerts but does not guide each movement

• BVLOS (Beyond Visual Line of Sight): Drone operations where the aircraft flies beyond the operator's direct visual range. Requires FAA waiver authorization in the United States.

• COPE framework: Construction, Occupancy, Protection, Exposure — the standard commercial insurance underwriting framework for assessing property risk. The Protection component scores security measures.

• DFR (Drone-as-First-Responder): Configuration where a security drone automatically launches to an alert location when any security system triggers — reaching any point on a 10-acre site in under 90 seconds

• Deterrence: Security measures that reduce the probability of incidents by making the property a less attractive target. Distinguished from documentation (recording what happened) and response (addressing incidents in progress).

E–L

• False alarm rate: The percentage of security alerts that do not correspond to genuine security events. Traditional motion detection systems have 94–98% false alarm rates; AI analytics systems achieve 10–30% false alarm rates.

• FAA Part 107: Federal Aviation Administration regulations governing commercial drone operations in the United States. Requires operator certification, aircraft registration, and compliance with operating rules.

• Full-Spectrum Automated Security: DSP's term for the integration of all five technology layers — fixed detection, aerial drone patrol, ground robotic systems, acoustic detection, and 24/7 RSOC — into a unified security architecture.

• Geofencing: Virtual geographic boundaries around a defined area that trigger automatic security alerts when GPS-tracked assets cross them

• IDLH (Immediately Dangerous to Life or Health): Environments where hazardous conditions create immediate life safety risk — relevant to security because robotic systems can inspect these areas without human exposure

• LPR (License Plate Recognition): Camera and software system that automatically reads and logs vehicle license plates. Used for vehicle inventory logging, ORC detection, and incident documentation.

M–R

• Mobile security unit: Self-contained, towable security infrastructure — typically a surveillance trailer — that deploys without electrical infrastructure or permits within hours

• Negligent security: Premises liability theory holding property owners responsible for criminal harm when failure to provide reasonable security measures was a proximate cause

• ORC (Organized Retail Crime): Coordinated theft operations involving multiple individuals with specific roles — distinct from opportunistic shoplifting. ORC targets retail properties with parking lot pre-theft surveillance.

• PIDS (Perimeter Intrusion Detection System): Physical sensors on perimeter barriers that detect contact or proximity — fence vibration sensors, laser tripwires, buried cable sensors

• PSaaS (Physical Security as a Service): Subscription delivery model for comprehensive physical security — hardware deployment, monitoring, maintenance, and technology refresh as a monthly service

• PSIM (Physical Security Information Management): Software platform aggregating data from multiple security systems into a unified operational interface for integrated monitoring and response

• Quadruped robot: Four-legged robotic patrol platform — Boston Dynamics Spot is the leading commercial example — capable of navigating stairs and uneven terrain that wheeled robots cannot access

• Racetrack patrol: Programmed drone patrol route that orbits a property at altitude in a defined oval pattern — providing systematic aerial coverage of the full site on each circuit

• RSOC (Remote Security Operations Center): Centralized monitoring facility where trained operators watch live feeds from cameras, drones, robots, and sensors across multiple client sites simultaneously — the human intelligence layer of automated security

S–Z

• SECaaS (Security as a Service): Subscription delivery model for security capabilities — applied to cybersecurity (cloud-based security services) and physical security (PSaaS)

• SLA (Service Level Agreement): Contractual definition of measurable performance standards with defined consequences for non-compliance

• Surveillance trailer: Self-contained mobile security unit on a trailer chassis with cameras, solar power, cellular connectivity, and two-way audio — deployable without infrastructure

• Thermal camera / Infrared camera: Camera that detects heat signatures rather than visible light — enabling detection in complete darkness and through light concealment

• Two-way audio: Security system capability enabling RSOC operators to both hear ambient sound from a monitored location and speak directly to individuals there through deployed speakers

• Uptime SLA: Contractual specification of minimum system availability — typically 99%+ for commercial security systems, with defined consequences for failures

• Verified response: Law enforcement policy requiring visual confirmation of criminal activity before dispatch — increasingly common in jurisdictions with high false alarm rates

• Video verification: Process of using live camera footage to confirm whether an alarm represents a genuine threat before law enforcement dispatch

• Virtual guard: RSOC operator who performs monitoring, assessment, verbal deterrence, and escalation remotely — serving the surveillance and deterrence functions of an on-site guard at lower cost

• VLOS (Visual Line of Sight): Standard FAA Part 107 requirement that drone operators maintain direct visual contact with the aircraft. BVLOS operations go beyond this range with FAA authorization.

FAQ: Security Glossary

What is the most important distinction in security technology vocabulary?

The most operationally significant distinction is between active monitoring and passive recording. Passive recording documents incidents after they occur. Active monitoring — 24/7 RSOC with live feeds, alert assessment, verbal deterrence, and law enforcement coordination — prevents incidents. Most commercial security programs have passive recording; comprehensive security programs have active monitoring.
