Full title and description

Video surveillance systems for use in security applications - Part 1-2: System requirements - Performance requirements for video transmission. This IEC international standard defines general requirements for the transmission of video used in security and surveillance applications, covering performance, security and conformance to basic IP connectivity based on established international protocols and best practices.

Abstract

IEC 62676-1-2:2013 provides minimum performance and reliability requirements for video transmission in IP-based security systems. It addresses timing, quality and availability requirements for surveillance video streams, gives guidance on network architectures to meet those requirements and specifies requirements for IP-based video transmission devices used in security applications.

Scope

This part of IEC 62676 specifies general requirements for video transmission in security applications, including minimum performance requirements for image transmission over IP networks (timing, quality, availability), security requirements for video transport, conformance to basic IP connectivity and guidance on network architectures and device requirements to meet security-surveillance performance objectives. Certain clauses define specific minimum performance values and the expectations for transmission devices used in surveillance systems.

Key topics and requirements

• Performance metrics for video transmission (latency, jitter, frame rate, packet loss tolerances and availability targets).
• Quality requirements for delivered video to satisfy security/surveillance use cases.
• Security considerations for video transport (integrity, confidentiality and access control expectations for IP networks).
• Conformance to basic IP connectivity and use of standard network protocols to enable interoperability.
• Guidance on network architectures and redundancy to meet timing and availability demands of surveillance systems.
• Requirements and expectations for video transmission devices (network interfaces, stream handling and event signalling in IP-based equipment).

The list above summarizes the principal technical areas addressed by IEC 62676-1-2:2013; the standard provides detail on minimum values, recommended practices and normative references used to achieve interoperable, secure and predictable video transmission for security applications.

Typical use and users

Used by surveillance system designers and integrators, network and security engineers, product manufacturers (camera, encoder, VMS and network-device vendors), standards writers, procurement teams and independent test laboratories to define, evaluate or verify video-transmission performance and interoperability in security applications. The document supports specification writing, acceptance testing and design of resilient IP network architectures for CCTV/video surveillance.

Related standards

IEC 62676 is a multipart series. Related parts include (but are not limited to): Part 1-1 (system requirements — general), Part 2-1 (video transmission protocols — general requirements) and other parts addressing video interfaces and application guidelines. This Part 1-2 is published alongside other IEC 62676 parts that together address system-level, protocol and interface interoperability for video surveillance. Regional adoptions have been issued (for example EN 62676-1-2:2014 and associated corrigenda).
