Part 4: Application guidelines

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.
IEC 62676-4 has been prepared by IEC technical committee 79: Alarm and electronic security
systems. It is an International Standard.
This second edition cancels and replaces the first edition published in 2014. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
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);
IEC 62676-4:2025 © IEC 2025
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:

1 Scope
This part of IEC 62676 describes the planning, design, installation, testing, commissioning, and
maintaining 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 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.

3.1.3
at-site visual check
activity to determine and assess the feasibility of implementing the safety concept per camera
location to be monitored as well as checks of visible disturbances and defects at site on the
monitoring tasks of a VSS that are not evaluated operationally and whether there are deviations
from the function of the VSS required in the safety concept
Note 1 to entry: In particular for influences occurring outside of VSS system parts.
Note 2 to entry: The at-site visual check is the responsibility of the operator, who can, however, hand over the
inspection to a competent person VSS or to a competent system engineer VSS.
3.1.4
camera housing
enclosure to provide both physical and environmental protection of the camera, lens and
ancillary equipment
3.1.5
camera sensitivity
image capturing device capability to produce an image in certain light conditions
3.1.6
characterise
defined functional purpose of a VSS camera to enable characterisation of a target, e.g. person
(type of person, gait and action can be characterised) and vehicles (vehicle brand can be
characterised) with a pixel density of > 250 pixels/meter
3.1.7
competent person VSS
person who has been instructed by a competent system engineer VSS about the assigned tasks
within the scope of the on-site check and the possible dangers and consequences of improper
behaviour
Note 1 to entry: This includes the necessary knowledge for the assessment of the object requirements, with regard
to the type of danger and the required function of the VSS, the influence of the use as well as the limits of use and
the instruction about the security concept of the video surveillance system, about existing requirements as well as
legal requirements or requirements of the operator from safety aspects as personal and property protection measures
or to avoid personal injury.
Note 2 to entry: The task requires competences for independent planning and processing of the requirements from
the at-site visual check as well as in-depth general knowledge and specialist theoretical knowledge in order to be
able to assess to what extent environmental or object changes can influence the effectiveness of a video surveillance
system. The recognition of possible interactions from other requirements as well as the development of alternative
actions is necessary. Detected deviations shall be securely justified, responsibly communicated and, if necessary,
retracted if no other problem solutions can be found.
