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

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC

edition:
a) implementing request for define a security concept (instead of just a risk analysis) (4.2);
b) selection of security grades (4.2.3);
c) complete redefinition of pixel densities (6.7) including new test charts (Annex C):
– upgrade of previous MDORII system with 6 pixel densities (12,5 pixels/meter; 25
pixels/meter; 62,5 pixels/meter ; 125 pixels/meter; 250 pixels/meter; 1 000 pixels/meter)
into new O2DCPVS system with 7 pixel densities (20 pixels/meter; 40 pixels/meter; 80
pixels/meter; 125 pixels/meter; 250 pixels/meter; 500 pixels/meter; 1 500 pixels/meter
d) operation of VSS (Clause 17);
e) security grading by size view (Annex D, Table D.2);
f) security grading by application (Annex D, Table D.3);
g) security grading by critical infrastructure (Annex D, Table D.4);
h) tables for number of frames depending on object speed (Annex D, Table D.5 and Table D.6);
i) general updates of tables in entire document.

INTRODUCTION
The IEC Technical Committee 79 in charge of alarm and electronic security systems together
with many governmental organisations, test houses and equipment manufacturers has 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
Each part offers its own clauses for the scope, normative references, definitions and
requirements.
The purpose of this part of IEC 62676 is to provide guidance on how to ensure that video
surveillance systems (VSS), thus far referred to as closed circuit television (CCTV), meet their
functional and performance requirements.
This part of IEC 62676 will prove useful to those responsible for establishing operational
requirements, writing specifications, selecting, installing, commissioning, using and maintaining
a VSS.
VSS, in its simplest form, is a means of providing images from security cameras and recorders
for viewing on a display via a transmission system. There is no theoretical limit to the number
of cameras and displays which may be used in a VSS installation but in practice will be limited
by the efficient combination of control and display equipment and the operator's ability to
manage the system.
The successful operation of a VSS requires the active co-operation of the user in carrying out
the recommended procedures.
Due to the wide range of VSS applications, for example security, safety, public safety,
transportation, etc. only the minimum requirements are covered in this part of IEC 62676.
1 Scope
This part of IEC 62676 gives recommendations and requirements for the selection, describes
the planning, design, installation, testing, commissioning, and maintaining and testing of video
surveillance systems (VSS) comprising image capture device(s), interconnection(s) and image
handling device(s), for use in security applications within private or public spaces.
The objectives of this document are to:
a) provide a framework to assist customers, installers and users all interested parties in
establishing their requirements,
b) assist specifiers and users in determining the appropriate equipment required for a given
application,
c) provide means of evaluating objectively the performance of the VSS.

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

b) selection of security grades (4.2.3);
c) complete redefinition of pixel densities (6.7) including new test charts (Annex C):
– upgrade of previous MDORII system with 6 pixel densities (12,5 pixels/meter; 25
pixels/meter; 62,5 pixels/meter ; 125 pixels/meter; 250 pixels/meter; 1 000 pixels/meter)
into new O2DCPVS system with 7 pixel densities (20 pixels/meter; 40 pixels/meter; 80
pixels/meter; 125 pixels/meter; 250 pixels/meter; 500 pixels/meter; 1 500 pixels/meter
d) operation of VSS (Clause 17);
e) security grading by size view (Annex D, Table D.2);
f) security grading by application (Annex D, Table D.3);
g) security grading by critical infrastructure (Annex D, Table D.4);
h) tables for number of frames depending on object speed (Annex D, Table D.5 and Table D.6);
i) general updates of tables in entire document.
The text of this International Standard is based on the following documents:
