IEC 62676-4:2025

Overview

IEC 62676-4:2025 - Video surveillance systems for use in security applications - Part 4: Application guidelines - provides comprehensive guidance for the lifecycle of video surveillance systems (VSS) used in private and public security applications. The standard covers planning, design, installation, testing, commissioning and maintenance of VSS comprised of image capture device(s), interconnection(s) and image handling device(s). It is intended to help organisations deliver reliable, legally defensible and operationally effective surveillance deployments.

Key topics and technical requirements

The standard addresses practical and technical aspects of VSS design and operation, including:

• Planning & risk assessment: security concept, selecting security grades, operational requirements, site surveys and site plans.
• System design: camera siting, fields of view, object sizing and pixel density, lens and housing selection, illumination and tamper protection.
• Equipment selection: camera types (including PTZ), lenses, housings, IP video equipment and interoperability considerations.
• Transmission & networking: wired and wireless link considerations, IP video performance classes and network-related requirements.
• Image quality & performance: resolution, frame rate, image compression and video performance characteristics.
• Storage & export: storage requirements, metadata (time/date/camera ID), encryption, export formats and replay of exported images.
• Control room configuration: display sizing/positioning, number of operator workstations, backup power and environmental protections.
• Testing & acceptance: development of test plans, factory/user/technical acceptance testing and image quality verification.
• Documentation & maintenance: design specifications, test plans, commissioning records, operating logbooks, preventive and corrective maintenance procedures.

Practical applications

IEC 62676-4 is practical guidance for anyone responsible for specifying, delivering or operating surveillance systems in commercial buildings, transport hubs, utilities, public spaces, retail environments and critical infrastructure. Typical uses include:

• Developing tender/operational requirement documents for VSS projects
• Designing camera coverage to meet identification and evidential needs
• Specifying IP video systems, storage and export workflows for compliance and forensic quality
• Creating commissioning and acceptance test plans to validate system performance
• Establishing maintenance contracts and operating procedures to ensure long-term reliability

Who should use this standard

• Security system designers and integrators
• Facility and security managers
• Project specifiers and procurement teams
• Installers, testers and commissioning engineers
• Regulators and stakeholders overseeing public-space surveillance
