SIST EN ISO 22311:2015 PDF

Overview

EN ISO 22311:2014 (ISO 22311:2012) - "Societal security - Video‑surveillance - Export interoperability" defines a common output file format and minimum technical requirements for exporting digital video‑surveillance content. The standard is intended primarily for societal security use (forensics, crime prevention, crisis management) and ensures that video, audio and associated metadata exported from CCTV systems (stand‑alone or large‑scale) can be exchanged via removable media or networks and reliably processed by end‑users.

Key elements:

• A common export package format (audio, video, encapsulation/packaging).
• A metadata dictionary (Annex A) and presentation/usability guidance (Annex B).
• Requirements for data security, integrity and privacy measures.

Key Topics and Requirements

• Export interoperability profile: Specifies an exchange format that combines selected technical standards to achieve interoperability across different vendors and systems.
• Media components: Covers video, audio and image encoding options and how they are packaged for export.
• Metadata: Defines descriptive (location, camera ID) and dynamic (time, PTZ, identification results) metadata required for processing and forensic use. Geo‑location and scene location concepts are included.
• Encapsulation/Packaging: Defines logical structure and packaging rules so exported files can be read by replay/analysis systems.
• Data security & integrity: Requirements for protecting exported data during transfer and storage to maintain evidential value.
• Privacy provisions: Measures to protect individuals’ rights when recordings include citizens (redaction, access controls, retention and disposal considerations).
• Usability guidance: Informative annex outlining how data presentation aids user processing and forensic workflows.

Applications and Who Uses It

EN ISO 22311 is practical for organizations and professionals involved in acquisition, exchange and analysis of CCTV data:

• Law enforcement, forensic analysts and public safety authorities needing interoperable evidence exports.
• CCTV manufacturers and video management system (VMS) providers implementing export interfaces.
• Systems integrators and IT teams responsible for secure transfer and playback of surveillance exports.
• Policy makers and standards bodies aligning procurement or procurement specifications with societal security needs.

Related Standards

EN ISO 22311 references and relies on existing technical standards rather than prescribing new codecs or methods. Notable referenced documents include:

• MPEG/ISO AVC and MP4 family (ISO/IEC 14496 series: AVC, ISO base media format, MP4)
• JPEG / JPEG 2000 (ISO/IEC 10918, ISO/IEC 15444)
• IEC 62676 series (video‑surveillance systems)
• SMPTE metadata standards, ITU G.711 (audio), and other MPEG/JPEG family standards

Using EN ISO 22311 helps ensure CCTV exports are interoperable, forensically sound and privacy‑aware-critical for cross‑agency sharing and long‑term evidential use.
