The principle that surveillance and intervention should be no more intrusive than necessary to achieve a legitimate security purpose, balancing risk against individual rights.

Related: Duty of Care, Privacy Masking
Code of Conduct

A written set of behavioral and ethical standards governing operator actions, including confidentiality, non-discrimination, honesty in reporting, and proper use of authority.

Related: Duty of Care, Confidentiality
Confidentiality

The duty to keep surveillance data, incident details, and personal information secret from unauthorized persons, sharing only on a legitimate need-to-know basis.

Related: Data Protection, Code of Conduct
Privacy Masking

A software function that blanks out selected areas of a camera image, such as neighboring windows or public footpaths, so they are not recorded or displayed.

Related: Proportionality, Field of View
Field of View

The area a camera can see at any moment, determined by lens focal length, sensor size, and camera position and orientation.

Related: Focal Length, Pan-Tilt-Zoom
Focal Length

The distance between a lens optical center and the sensor; shorter lengths give wide views, longer lengths magnify distant subjects at the cost of coverage.

Related: Field of View, Varifocal Lens
Varifocal Lens

A lens whose focal length can be adjusted manually during installation, allowing the installer to fine-tune coverage and magnification for a specific scene.

Related: Focal Length, Pan-Tilt-Zoom
Pan-Tilt-Zoom

A motorized camera mount that rotates horizontally, tilts vertically, and changes magnification, letting an operator track activity across a wide area.

Related: Preset Position, Field of View
Preset Position

A stored combination of pan, tilt, and zoom values that returns a camera instantly to a chosen view, often triggered by an alarm or patrol tour.

Related: Pan-Tilt-Zoom, Camera Patrol
Resolution

The amount of detail a camera can capture, usually expressed in pixels or lines; higher resolution supports identification but increases storage and bandwidth demand.

Related: Bit Rate, Evidence Quality
Bit Rate

The volume of data a video stream produces per second, affecting image quality, network load, and how long recordings fit on available storage.

Related: Resolution, Retention Period
Frame Rate

The number of images a camera captures per second; higher rates show smoother motion, which matters when reviewing fast-moving incidents.

Related: Resolution, Evidence Quality
Ergonomic Workstation

A control room desk setup adjusted for screen height, viewing distance, seating support, and reach, reducing strain during long monitoring shifts.

Related: Fatigue Management, Screen Fatigue
Fatigue Management

Planned practices such as shift rotation, scheduled breaks, lighting control, and workload limits that reduce operator tiredness and attention lapses.

Related: Vigilance Decrement, Ergonomic Workstation
Vigilance Decrement

The natural decline in detection performance during long, monotonous monitoring tasks, managed through breaks, task rotation, and active patrol routines.

Related: Fatigue Management, Camera Patrol
Screen Fatigue

Eye strain, headache, and blurred vision caused by prolonged close viewing of monitors, eased by correct viewing distance, breaks, and lighting control.

Related: Ergonomic Workstation, Fatigue Management
Camera Patrol

A programmed sequence in which cameras move through preset views or an operator systematically scans all views to detect anomalies.

Related: Preset Position, Target Observation
Target Observation

Sustained, discreet monitoring of a specific person, vehicle, or area, recording movements and descriptions without alerting the subject.

Related: Camera Patrol, Handover Log
Alarm Verification

The process of confirming whether an alarm reflects a genuine incident by checking video, sensors, or field staff before escalating the response.

Related: False Alarm, Alarm Response
False Alarm

An alarm triggered without a real security incident, caused by equipment faults, environmental conditions, animals, or user error.

Related: Alarm Verification, Intrusion Detection
Alarm Response

The documented sequence of actions after an alarm, including verification, assessment, notification, dispatch, and logging of the outcome.

Related: Alarm Verification, Incident Log
Radio Discipline

Structured communication rules covering call signs, clear speech, brevity, channel sharing, and priority traffic, keeping the radio net usable in emergencies.

Related: Call Sign, Handover Log
Call Sign

A short, unique identifier assigned to an operator, patrol, or post, used on radio instead of names for speed, clarity, and confidentiality.

Related: Radio Discipline, Escalation
Escalation

The process of passing an incident up through defined levels of authority or to emergency services when it exceeds the operator's remit or severity threshold.

Related: Alarm Response, Call Sign
Chain of Custody

A documented, unbroken record of who handled evidence, when, where, and for what purpose, from seizure through storage to presentation in court.

Related: Evidence Integrity, Evidence Export
Evidence Integrity

The assurance that recorded material is complete, unaltered, and authentic, supported by hashing, access controls, and audit trails.

Related: Chain of Custody, Evidence Export
Evidence Export

The controlled process of copying selected footage and metadata to a sealed, labeled medium for investigation or court, with the original preserved.

Related: Evidence Integrity, Chain of Custody
Retention Period

The defined length of time recordings are kept before automatic overwrite or deletion, set by policy, law, and storage capacity.

Related: Data Protection, Bit Rate
Data Protection

Legal and procedural rules governing collection, storage, access, and disposal of personal data such as images of identifiable individuals.

Related: Confidentiality, Retention Period
Access Control

Systems and procedures that limit entry to premises or data to authorized persons, using credentials, readers, PINs, or operator permissions.

Related: Intrusion Detection, Need-to-Know
Intrusion Detection

Sensors and analytics that detect unauthorized entry into a protected area, such as door contacts, motion detectors, beams, and fence sensors.

Related: Access Control, Alarm Verification
Integrated Security System

A platform linking video, alarms, access control, and fire systems so events can be cross-checked and managed from one operator interface.

Related: Intrusion Detection, Alarm Verification
Incident Log

A chronological, factual record of events, actions, times, and decisions made in the control room, used for review and legal purposes.

Related: Handover Log, Alarm Response
