FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62676-1-2 has been prepared by IEC technical committee 79:

Alarm and electronic security systems.
The text of this standard is based on the following documents:

INTRODUCTION

The IEC Technical Committee 79 in charge of alarm and electronic security systems together

with many governmental organisations, test houses and equipment manufacturers have

defined a common framework for video surveillance transmission in order to achieve

interoperability between products.

The IEC 62676 series of standards on video surveillance system is divided into 4 independent

parts:
Part 1: System requirements
Part 2: Video transmission protocols
Part 3: Analog and digital video interfaces
Part 4: Application guidelines (to be published)

Each part has its own clauses on scope, references, definitions and requirements.

This IEC 62676-1 series consists of 2 subparts, numbered parts 1-1 and 1-2 respectively:

IEC 62676-1-1, System requirements – General

IEC 62676-1-2, System requirements – Performance requirements for video transmission

The second subpart of this IEC 62676-1 series applies to video transmission. The purpose of

the transmission system in a Video Surveillance System (VSS) installation is to provide

reliable transmission of video signals between the different types of VSS equipment in

security, safety and monitoring applications.

Today VSS reside in security networks using IT infrastructure, equipment and connections

within the protected site itself.

VIDEO SURVEILLANCE SYSTEMS
FOR USE IN SECURITY APPLICATIONS –
Part 1-2: System requirements –
Performance requirements for video transmission
1 Scope

This part of IEC 62676 introduces general requirements on video transmission. This standard

covers the general requirements for video transmissions on performance, security and

conformance to basic IP connectivity, based on available, well-known, international standards.

Clauses 4 and 5 of this standard define the minimum performance requirements on video

transmission for security applications in IP networks. In surveillance applications the

requirements on timing, quality and availability are strict and defined in the last section of this

standard. Guidelines for network architecture are given, how these requirements can be

fulfilled.

Clause 6 and the next clauses of this standard define requirements on basic IP connectivity of

video transmission devices to be used in security applications. If a video transmission device

is used in security, certain basic requirements apply. First of all a basic understanding of IP

connectivity needs to be introduced which requests the device to be compliant to fundamental

network protocols. These could be requirements which may be applied to all IP security

devices even beyond IP video. For this reason requirements are introduced in a second step

for compliance to basic streaming protocols, used in this standard for video streaming and

stream control. Since security applications need high availability and reliability, general

means for the transmission of the video status and health check events have to be covered.

These are defined in general requirements on eventing and network device management. In

security proper maintenance and setup is essential for the functioning of the video

transmission device. Locating streaming devices and their capabilities is a basic requirement

and covered in ´device discovery and description´.
